This document is the 5th of 12 Parts of the official triennial compilation and publication of the adoptions, amendments and repeal of administrative regulations to California Code of Regulations, Title 24, also referred to as the California Building Standards Code. Part 5 is known as the California Plumbing Code and incorporates, by adoption, the 2009 edition of the Uniform Plumbing Code of the International Association of Plumbing and Mechanical Officials with the California amendments.
The California Building Standards Code is published in its entirety every three years by order of the California legislature, with supplements published in intervening years. The California legislature delegated authority to various State agencies, boards, commissions and departments to create building regulations to implement the State′s statutes. These building regulations or standards, have the same force of law, and take effect 180 days after their publication unless otherwise stipulated. The California Building Standards Code applies to occupancies in the State of California as annotated.
A city, county, or city and county may establish more restrictive building standards reasonably necessary because of local climatic, geological or topographical conditions. Findings of the local condition(s) and the adopted local building standard(s) must be filed with the California Building Standards Commission to become effective and may not be effective sooner than the effective date of this edition of California Building Standards Code. Local building standards that were adopted and applicable to previous editions of the California Building Standards Code do not apply to this edition without appropriate adoption and the required filing.
To familiarize yourself with the format of this code, it is suggested that users review the following contents:

Revised: February 24, 2010
The advantages of a uniform plumbing code adopted by various local jurisdictions has long been recognized. Disorder in the industry as a result of widely divergent plumbing practices and the use of many different, often conflicting, plumbing codes by local jurisdictions influenced the Western Plumbing Officials Association (now the International Association of Plumbing and Mechanical Officials [IAPMO]) to form a committee of plumbing inspectors, master and journeyman plumbers, and sanitary and mechanical engineers, assisted by public utility companies and the plumbing industry to create a basic plumbing document for general use. The product of this effort, the first edition of the Uniform Plumbing Code® (UPC®) was officially adopted by IAPMO in 1945. The widespread use of this code over the past five decades by jurisdictions throughout the United States and internationally is testament to its merit.
With the publication of the 2003 Edition of the Uniform Plumbing Code®, another significant milestone was reached. For the first time in the history of the United States, a plumbing code was developed through a true consensus process. The 2009 edition represents the most current approaches in the plumbing field and is the second edition developed under the ANSI consensus process. Contributions to the content of the code were made by every segment of the built industry, including such diverse interests as consumers, enforcing authorities, installers/maintainers, insurance, labor, manufacturers, research/standards/testing laboratories, special experts, and users.
The UPC is designed to provide consumers with safe and sanitary plumbing systems while, at the same time, allowing latitude for innovation and new technologies. The public at large is encouraged and invited to participate in IAPMO's open consensus code development process. This code is updated every three years. A code development timeline and other relevant information is available at IAPMO's website at www.iapmo.org.
The Uniform Plumbing Code® is dedicated to all those who, in working to achieve "the ultimate plumbing code," have unselfishly devoted their time, effort, and personal funds to create and maintain this, the finest plumbing code in existence today.
The 2009 Uniform Plumbing Code® is supported by the American Society of Sanitary Engineering (ASSE), the Mechanical Contractors Association of America (MCAA), the Plumbing-Heating-Cooling Contractors National Association (PHCC-NA), the United Association (UA), and the World Plumbing Council (WPC). The presence of these logos, while reflecting support, does not imply any ownership of the copyright to the UPC, which is held exclusively by IAPMO. Further, the logos of these associations indicates the support of IAPMO's open, consensus process being used to develop IAPMO's codes and standards.

1.11.2.1.2 Pursuant to Health and Safety Code Section 13108, and except as otherwise provided in this section, building standards adopted by the State Fire Marshal published in the California Building Standards Code relating to fire and panic safety shall be enforced by the State Fire Marshal in all state –owned buildings, state –occupied buildings, and state owned buildings, state –occupied buildings, and state institutions throughout the state. Upon the written request of the chief fire official of any city, county, or fire-protection district, the State Fire Marshal may authorize such chief fire official and his or her authorized representatives, in their geographical area of responsibility, to make fire-prevention inspections of state-owned or state-occupied buildings, other than state institutions, for the purpose of enforcing the regulations relating to fire and panic safety adopted by the State Fire Marshal pursuant to this section and building standards relating to fire and panic safety published in the California Building Standards Code. Authorization from the State Fire Marshall shall be limited to those fire departments or fire districts which maintain a fire-prevention bureau staffed by paid personnel.
Pursuant to Health and Safety Code Section 13108, any requirement or order made by any chief fire official who is authorized by the State Fire Marshal to make fire-prevention inspections of state –owned or state-occupied buildings, other than state institutions, may be appealed to the State Fire Marshal. The State Fire Marshal shall, upon receiving an appeal and subject to the provisions of Chapter 5 (commencing with Section 18945) of Part 2.5 of Division 13 of the Health and Safety Code, determine if the requirement or order made is reasonably consistent with the fire and panic safety regulations adopted by the State Fire Marshal and building standards relating to fire and panic safety published in the California Building Code.
Any person may request a code interpretation from the State Fire Marshal relative to the intent of any regulation or provision adopted by the State Fire Marshal. When the request relates to a specific project, occupancy or building, the State Fire Marshal shall review the issue with the appropriate local enforcing agency prior to rendering such code interpretation.

A person is guilty of a separation offense each day during which he or she commits, continues, or permits a violation of any provision of, or any order, rule or regulation of, the State Fire Marshall as contained in this code.
Any inspection authority who, in the exercise of his or her authority as a deputy State Fire Marshal, causes and legal complaints to be filed or any arrest to be made shall notify the State Fire Marshal immediately following such action.
1.11.2.2 Right of Entry. The fire chief of any city, county, or fire-protection district, or such person’s authorized representative, may enter any state institution or any other state-owned or state-occupied building for the purpose of preparing a fire –suppression preplanning program or for the purpose of investigating any fire in a state-occupied building.
The State Fire Marshal, his or her deputies or salaried assistants, the chief of any city or county fire department or fire-protection district and his or her authorized representatives may enter any building or premises not used for dwelling purposes at any reasonable hour for the purpose of enforcing this chapter. The owner, lessee, manager, or operator of any such building or premises shall permit the State Fire Marshal, his or her deputies or salaried assistants and the chief of any city or county fire department or fire-protection district and his or her authorized representatives to enter and inspect them at the time and for the purpose stated in this section.

1.11.2.3.1 Any fire-protection district organized pursuant to Health and Safety Code Part 2.7 (commencing with Section 13800) of Division 12 may adopt building standards relating to fire and panic safety that are more stringent than those building standards adopted by the State Fire Marshal and contained in the California Building Standards Code. For these purposes, the district board shall be deemed a legislative body and the district shall be deemed a local agency. Any changes or modifications that are more stringent than the requirements published in the California Building Standards Code relating to fire and panic safety shall be subject to Section 1.1.8.1.
1.11.2.3.2 Any fire protection district that proposes to adopt an ordinance pursuant to this section shall, not less than 30 days prior to noticing a proposed ordinance for public hearing, provide a copy of that ordinance, together with the adopted findings made pursuant to Section 1.11.2.3.1, to the city, county, or city and county where the ordinance will apply. The city, county, or city and county may provide the district with written comments, which shall become part of the fire-protection district’s public hearing record.
1.11.2.3.3 The fire-protection district shall transmit the adopted ordinance to the city, county, or city and county where the ordinance will apply. The legislative body of the city, county, or city and county may ratify, modify or deny an adopted ordinance and transmit its determination to the district within 15 days of the determination. Any modification or denial of an adopted ordinance shall include a written statement
describing the reasons for any modifications or denial. No ordinance adopted by the district shall be effective until ratification by the city, county, or city and county where the ordinance will apply. Upon ratification of an adopted ordinance, the city, county, or city and county shall file a copy of the findings of the district, and any findings of the city, county, or city and county together with the adopted ordinance expressly marked and identified to which each finding refers, in accordance with Section 1.1.8.1(3).

FIGURE G.1(k) USE OF MANIFOLDED COMMON VENT CONNECTOR.
FIGURE G.1(l) USE OF OFFSET COMMON VENT.
G.1.1 Example 1: Single Draft-Hood-Equipped Appliance. An installer has 120,000-Btu/h input appliance with a five (5) inch diameter draft hood outlet that needs to be vented into a ten (10) foot high Type B vent system. What size vent should be used assuming (1) a five (5) foot lateral single-wall metal vent connector is used with two (2) 90 degree elbows or (2) a five (5) foot lateral single-wall metal vent connector is used with three (3) 90 degree elbows in the vent system? (See Figure G.1.1).
Solution
Table 5-9 should be used to solve this problem because single-wall metal vent connectors are being used with a Type B vent, as follows:
FIGURE G.1(m) MULTISTORY GAS VENT DESIGN PROCEDURE
FOR EACH SEGMENT OF SYSTEM
122,000 x 0.90 = 110,000 for five (5) inch vent
From Table 5-10, select six (6) inch vent.
186,000 x 0.90 = 167,000
This figure is exceeding the required 120,000. Therefore, use a six (6) inch vent and connector where three (3) elbows are used.
G.1.2. Example 2: Single Fan-Assisted Appliance. An installer has an 80,000 Btu/h input fan-assisted appliance that must be installed using ten (10) feet of lateral connector attached to a thirty (30) foot high Type B vent. Two (2) 90 degree elbows are needed for the installation. Can a single-wall metal vent connector be used for this application? See Figure G.1.2.
Solution
Table 5-9 refers to the use of single-wall metal vent connectors with Type B vent. In the first column find the row associated with a thirty (30) foot height and a ten (10) foot lateral. Read across this row, looking at the FAN Min and FAN Max columns, to find that a three (3) inch diameter single-wall metal vent connector is not recommended. Moving to the next larger
FIGURE G.1(n) PRINCIPLES OF DESIGN OF MULTISTORY VENTS USING VENT CONNECTOR AND COMMON VENT DESIGN TABLES.
size single-wall connector (four (4) inch), we find that a four (4) inch diameter single-wall metal connector has a recommended maximum vent capacity of 144,000 Btu/h. The 80,000 Btu/h fan-assisted appliance is outside this range, so the conclusion is that a single-wall metal connector could be used to vent the appliance. Table 5-9 shows the acceptable range of vent capacities for a four (4) inch vent with five (5) feet of lateral to be between 72,000 Btu/h and 157,000 Btu/h.
If the appliance cannot be moved closer to the vertical vent, then a Type B vent could be used as the connector material. In this case, Table 5-8 shows that, for a thirty (30) foot high vent with ten (10) feet of lateral, the acceptable range of vent capacities for a four (4) inch diameter vent attached to a fan-assisted appliance is between 37,000 Btu/h and 150,000 Btu/h.
G.1.3. Example 3: Interpolating Between Table Values. An installer has an 80,000 Btu/h input appliance with a four (4) inch diameter draft hood outlet that needs to be vented into a twelve (12) foot high Type B vent. The vent connector has a 5-foot lateral length and is also Type B vent. Can this appliance be vented using a four (4) inch diameter vent?
Solution
Table 5-8 is used in the case of an all Type B Vent system. However, since there is no entry in Table 5-8 for a height of twelve (12) feet, interpolation must be used. Read down the four (4) inch diameter. NAT Max column to the row associated with a ten (10) foot height and five (5) foot lateral to find the capacity value of 77,000 Btu/h. Read further down to the fifteen (15) foot height, five (5) foot lateral row to find the capacity value of 87,000 Btu/h. The difference between the fifteen (15) foot height capacity value and the ten (10) foot height capacity value is 10,000 Btu/h. The capacity for a vent system with a twelve (12) foot height is equal to the capacity for a ten (10) foot height plus two-fifths (⁄25) of the difference between the ten (10) foot and height plus two-fifths (25) for the difference between the ten (10) foot and fifteen (15) foot height values, or 77,000 +2/5 x 10,000 = 81,000 Btu/h. Therefore, a four (4) inch diameter vent can be used in the installation.
G.2 Examples Using Common Venting Tables.
G.2.1 Example 4: Common Venting Two Draft-Hood- Equipped Appliances. A 35,000-Btu/h water heater is to be common vented with a 150,000 Btu/h furnace, using a common vent with a total height of thirty (30) feet. The connector rise is two (2) feet for the water heater with a horizontal length of four (4) feet. The connector rise for the furnace is three (3) feet with a horizontal length of eight (8) feet. Assume single-wall metal connectors will be used with Type B vent. What size connectors and combined vent should be used in this installation?
See Figure G.2.1.

FIGURE G.1.2 SINGLE FAN-ASSISTED APPLIANCE – EXAMPLE 2
FIGURE G.2.1 COMMON VENTING TWO DRAFT HOOD-EQUIPPED APPLIANCES – EXAMPLE 4
Solution
Table 5-15 should be used to size single-wall metal vent connectors attached to Type B vertical vents. In the vent connector capacity portion of Table 5-15, find the row associated with a thirty (30) foot vent height. For a two (2) foot rise on the vent connector for the water heater, read the shaded columns for draft-hood-equipped appliances to find that a three (3) inch diameter vent connector has a capacity of 37,000 Btu/h. Therefore, a three (3) inch single-wall metal vent connector can be used with the water heater. For a draft-hood-equipped furnace with a three (3) foot rise, read across the appropriate row to find that a five (5) inch diameter vent connector has a maximum capacity of 120,000 Btu/h. (which is too small for the furnace), and a six (6) inch diameter vent connector has a maximum vent connector should be used with the 150,000 Btu/h furnace. Since both vent connector horizontal lengths are less than the maximum lengths listed in Table 5-8, the table values can be used without adjustments.
In the common vent capacity portion of Table 5-15, find the row associated with a thirty (30) foot vent height and read over to the NAT + NAT portion of the six (6) inch diameter column to find a maximum combined capacity of 257,000 Btu/h. Since the two (2) appliances total only 185,000 Btu/h, a six (6) inch common vent can be used.
G.2.2 Example 5(a): Common Venting a Draft-Hood-Equipped Water Heater with a Fan-Assisted Furnace into a Type B Vent. In this case, a 35,000-Btu/h input draft-hood-equipped water heater with a four (4) inch diameter draft hood outlet, two (2) feet of connector rise, and four (4) feet of horizontal length is to be common vented with a 100,000 Btu/h fan-assisted furnace with a four (4) inch diameter flue collar, three (3) feet of connector rise, and six (6) feet of horizontal length. The common vent consists of a thirty (30) foot height of Type B vent. What are the recommended vent diameters for each connector and the common vent? The installer would like to use a single-wall metal vent connector. See Figure G.2.2.
Solution (See Table 5-15)
Water Heater Vent Connector Diameter. Since the water heater vent connector horizontal length of four (4) feet is less than the maximum value listed in Table 5-15, the venting table values can be used without adjustment. Using the Vent Connector Capacity portion of Table 5-15, read down the Total Vent Height (H) column to thirty (30) feet and read across the two (2) feet Connector Rise (R) row to the first Btu/h rating in the NAT Max column that is equal to or exceeding the water heater input rating. The table shows that a three (3) inch vent connector has a maximum input rating of 37,000 Btu/h. Although this rating is exceeding the water heater input rating, a three (3) inch vent is exceeding the water heater input rating, a three (3) inch vent connector is prohibited by Section 511.1.1(5). A four (4) inch vent connector has a maximum input rating of 67,000 Btu/h and is equal to the draft hood outlet diameter. A four (4) inch vent connector is

selected. Since the water heater is equipped with a draft hood, there are no minimum input rating restrictions.
Furnace Vent Connector Diameter. Using the Vent Connector Capacity portion of Table 5-15, read down the Total Vent Height (H) column to thirty (30) feet and across the three (3) foot Connector Rise (R) row. Since the furnace has a fanassisted combustion system, find the first FAN Max column with a Btu⁄h rating exceeding the furnace input rating. The four (4) inch vent connector has a maximum input rating of 119,000 Btu⁄h and a minimum input rating of 85,000 Btu⁄h.
The 100,000-Btu⁄h furnace in this example falls within this range, so a four (4) inch connector is adequate. Since the furnace vent connector horizontal length of six (6) feet is less than the maximum value listed in Table 5-8, the venting table values can be used without adjustment. If the furnace had an input rating of 80,000 Btu⁄h then a Type B vent connector would be needed in order to meet the minimum capacity limit (See Table 5-14).
Common Vent Diameter. The total input to the common vent is 135,000 Btu⁄h. Using the Common Vent Capacity portion of Table 5-15, read down the Vent Height (H) column to thirty (30) feet and across this row to find the smallest vent diameter in the FAN + NAT column that has a Btu⁄h rating equal to or exceeding 135,000 Btu⁄h. The four (4) inch common vent has a capacity of 132,000 Btu⁄h and the five (5) inch common vent has a capacity of 202,000 Btu⁄h. Therefore, the five (5) inch common vent should be used in this example.
Summary: In this example, the installer can use of four (4) inch diameter, single-wall metal vent connector for the water heater and a four (4) inch diameter, single-wall metal vent connector for the furnace. The common vent should be a five (5) inch diameter Type B vent.
G.2.3 Example 5(b): Common Venting into an Interior Masonry Chimney. In this case, the water heater and fan-assisted furnace of Example 5(a) are to be common-vented into a claytile-lined masonry chimney with a thirty (30) foot height. The chimney is not exposed to the outdoors below the roof line. The internal dimensions of the clay tile liner are nominally eight (8) inches x twelve (12) inches. Assuming the same vent connector heights, laterals, and materials found in example 5(a), what are the recommended vent connector diameters, and is this an acceptable installation
Solution
Table 5-17 is used to size common venting installations involving single-wall connectors into masonry chimneys.
Water Heater Vent Connector Diameter. Using Table 517, Vent Connector Capacity, read down the Vent Height (H) column to thirty (30) feet, and read across the two (2) foot Connector Rise (R) row to the first Btu⁄h rating in the NAT Max column that is equal to or exceeding the water heater input rating. The table shows that a three (3) inch vent connector has a maximum input of only 31,000 Btu⁄h, while a four (4) inch vent connector has a maximum input of 57,000 Btu⁄h. A four (4) inch vent connector must therefore be used.
Furnace Vent Connector Diameter. Using the Vent Connector Capacity portion of Table 5-17, read down the total Vent Height (H) Column to thirty (30) feet and across the three (3) feet Connector Rise (R) row. Because the furnace has a fan-assisted combustion system, find the first FAN Max column with a Btu⁄h rating exceeding the furnace input rating. The four (4) inch vent connector has a maximum input rating of 127,000 Btu⁄h and a minimum input rating of 95,000 Btu⁄h. The 100,000 Btu⁄h furnace in this example falls within this range, so a four (4) inch connector is adequate.
Masonry Chimney. From Table G.2.3, the equivalent area for a nominal liner size of eight (8) inches x twelve (12) inches is sixty-three and six-tenths (63.6) of a square inch. Using Table 5-17, Common Vent Capacity, read down the FAN + NAT column under the Minimum Internal Area of Chimney value of sixty-three (63) to the row for thirty (30) foot height to find a capacity value of 739,000 Btu⁄h. The combined input rating of the furnace and water heater, 135,000 Btu⁄h, is less than the table value so this is an acceptable installation.
Section 511.1.8 requires the common vent area to not exceed seven (7) times the smallest listed appliance categorized vent area, flue collar area, or draft hood outlet area. Both appliances in this installation have four (4) inch diameter outlets. From Table G.2.3, the equivalent area for an inside diameter of four (4) inches in twelve and two-tenths (12.2) of a square inch. Seven (7) times twelve and two-tenths (12.2) equals eighty-five and four-tenths (85.4), which is exceeding sixtythree and six-tenths (63.6), so this configuration is acceptable.
G.2.4 Example 5(c): Common Venting into an Exterior Masonry Chimney. In this case, the water heater and fan-assisted furnace of Examples 5(a) and 5(b) are to be commonvented into an exterior masonry chimney. The chimney height, clay-tile-liner dimensions, and vent connector heights and laterals are the same as in Example 5(b). This system is being installed in Charlotte, North Carolina. Does this exterior masonry chimney need to be relined? If so, what corrugated metallic liner size is recommended? What vent connector diameters are recommended? See Table G.2.3 and Figure 5-14.
Solution
According to 511.2.17, Type B vent connectors are required to be used with exterior masonry chimneys. Use Table 5-21 and Table 5-22 to size FAN+NAT common venting installations involving Type-B double-wall connectors into exterior masonry chimneys.
The local 99 percent winter design temperature needed to use Table 5-21 and Table 5-22 to can be found in the ASHRAE Handbook– Fundamentals. For Charlotte, North carolina, this design temperature is 19°F (-7.22°C).
Chimney Liner Requirement. As in Example 5(b), use the sixty-three (63) square inch column of Table 5-21 to the thirty
(30) foot height row to find that the combined appliance maximum input is 747,000 Btu⁄h. The combined input rating of the appliance in this installation, 135,000 Btu⁄h, is less than the maximum value, so this criterion is satisfied. Table 5-22, at a 19°F (-7.22°C) design temperature, and at the same vent height and internal area used earlier, shows that the minimum allowable input rating of a space-heating appliance is 470,000 Btu⁄h. The furnace input rating of 100,000 Btu⁄h is less than this minimum value. So this criterion is not satisfied, and an alternative venting design needs to be used, such as a Type B vent shown in Example 5(a) or a listed chimney liner system shown in the rest of the example.
According to Section 511.2.19, Table 5-9 or Tables 5-14 or 5-15 are used for sizing corrugated metallic liners in masonry chimneys, with the maximum common vent capacities reduced by 20 percent. This example will be continued assuming Type B vent connectors.
Water Heater Vent Connector Diameter. Using Table 5-14 Connector Capacity, read down the total Vent Height (H) column to thirty (30) feet, and read across the two (2) foot Connector Rise (R) row to the first Btu⁄hour rating in the Nat Max column that is equal to or exceeding the water heater input rating. The table shows that a three (3) inch vent connector has a maximum capacity of 39,000 Btu⁄h. Although this rating is exceeding the water heater input rating, a three (3) inch vent connector is prohibited by Section 511.1.6. A four (4) inch vent connector has a maximum input rating of 70,000 Btu⁄h and is equal to the draft hood outlet diameter. A four (4) inch vent connector is selected.
Furnace Vent Connector Diameter. Using Table 5-14, Vent Connector Capacity, read down the total Vent Height (H) column to thirty (R) feet, and read across the three (3) foot Connector Rise (R) row to the first Btu⁄h rating in the FAN MAX column that is equal to or exceeding the furnace input rating. The 100,000 Btu⁄h furnace in this example falls within this range, so a four (4) inch connector is adequate.
Chimney Liner Diameter. The total input to the common vent is 135,000 Btu⁄h. Using the Common Vent Capacity portion of Table 5-14, read down the total Vent Height (H) column to thirty (30) feet and across this row to find the smallest vent diameter in the FAN + NAT column that has a Btu⁄h rating exceeding 135,000 Btu⁄h.The four (4) inch common vent has a capacity of 138,000 Btu⁄h. Reducing the maximum capacity by 20 percent (See 13.2.19) results in a maximum capacity for a four (4) inch corrugated liner of 110,000 Btu⁄h, less than the total input of 135,000 Btu⁄h. So a larger liner is needed. The five (5) inch common vent capacity listed in Table 5-14 is 210,000 Btu⁄h, and after reducing by 20 percent is 168,000 Btu⁄h. Therefore, a five (5) inch corrugated metal liner should be used in this example.
Single Wall Connectors. Once it has been established that relining the chimney is necessary, Type B double-wall vent connectors are not specifically required. This example could be redone using Table 5-15 for single-wall vent connectors. For this case, the vent connector and liner diameters would be the same as found for Type B double-wall connectors.

Water piping systems shall be designed to ensure that the maximum velocities allowed by the code and the applicable standard are not exceeded.
610.2 Whenever a water filter, water softener, backflow prevention device or similar device is installed in any water supply line, the pressure loss through such devices shall be included in the pressure loss calculations of the system, and the water supply pipe and meter shall be adequately sized to provide for any such pressure loss.
No water filter, water softener, backflow prevention device, or similar device regulated by this code shall be installed in any potable water supply piping when the installation of such device produces an excessive pressure drop in any such water supply piping. In the absence of specific pressure drop information, the diameter of the inlet or outlet of any such device or its connecting piping shall be not less than the diameter of such water distribution piping to the fixtures served by the device.
Such devices shall be of a type approved by the Authority Having Jurisdiction and shall be tested for flow rating and pressure loss by an approved laboratory or recognized testing agency to standards consistent with the intent of this chapter.
610.3 The quantity of water required to be supplied to every plumbing fixture shall be represented by fixture units, as shown in Table 6-5. Equivalent fixture values shown in Table 6-5 include both hot and cold water demand.
610.4 Systems within the range of Table 6-6 shall be permitted to be sized from that table or by the method set forth in Section 610.5.
Listed parallel water distribution systems shall be installed in accordance with their listing, but at no time shall any portion of the system exceed the maximum velocities allowed by the code.
610.5 Except as provided in Section 610.4, the size of each water piping system shall be determined in accordance with the procedure set forth in Appendix A. For alternate methods of sizing water supply systems, see Appendix L.
610.6 Except where the type of pipe used and the water characteristics are such that no decrease in capacity due to length of service (age of system) is expected, friction-loss data shall be obtained from the “Fairly Rough” or “Rough” charts in Appendix A of this code. Friction or pressure losses in water meter, valve, and fittings shall be obtained from the same sources. Pressure losses through water-treating equipment, backflow prevention devices, or other flow-restricting devices shall be computed as required by Section 610.2.
610.7 On any proposed water piping installation sized using Table 6-6, the following conditions shall be determined:
610.8 Size of Meter and Building Supply Pipe Using Table 6-6. The size of the meter and the building supply pipe shall be determined as follows:
No building supply pipe shall be less than three-quarters (¾) of an inch (20 mm) in diameter.
610.9 Size of Branches. When Table 6-6 is used, the minimum size of each branch shall be determined by the number of fixture units to be served by that branch, the total developed length of the system, and the meter and street service size as per Section 610.8. No branch piping is required to be larger in size than that required by Table 6-6 for the building supply pipe.
610.10 Sizing for Flushometer Valves. When using Table 6-6 to size water supply systems serving flushometer valves, the number of flushometer fixture units assigned to every section of pipe, whether branch or main, shall be determined by the number and category of flushometer valves served by that section of pipe, in accordance with Table 6-7. Piping supplying a flushometer valve shall be not less in size than the valve inlet.
When using Table 6-7 to size water piping, care must be exercised to assign flushometer fixture units based on the number and category of fixtures served.
SIZING METHOD EXAMPLE USING TABLE 6-7 PUBLIC USE FIXTURES
In the example below, fixture units assigned to each section of pipe are computed as follows: Note: Each capital letter refers to the section of pipe above it, unless otherwise shown.
A: 1 WC = 40 F.U.
B: 2 WC = 70 F.U.
C: 2 WC (70) + 1 UR (20) = 90 F.U.
D: 2 WC (70) + 2 UR (35) = 105 F.U.
E: 2 WC (70) + 2 UR (35) + 1 LAV (1) = 106 F.U.
F: 2 WC (70) + 2 UR (35) + 2 LAV (2) = 107 F.U.
G: 1 LAV = 1 F.U.
H: 2 LAV = 2 F.U.
I: 2 LAV (2) + 1 UR (20) = 22 F.U.
J: 2 LAV (2) + 2 UR (35) = 37 F.U.
K: 2 LAV (2) + 2 UR (35) + 1 WC (40) = 77 F.U.
L: 2 LAV (2) + 2 UR (35) + 2 WC (70) = 107 F.U.
M: 4 WC (105) + 4 UR (53) + 4 LAV (4) = 162 F.U.
N: 1 WC = 40 F.U.
O: 1 WC (40) + 1 UR (20) = 60 F.U.
P: 1 WC (40) + 1 UR (20) + 1 LAV (1) = 61 F.U.
Q: 2 WC (70) + 1 UR (20) + 1 LAV (1) = 91 F.U.
R: 2 WC (70) + 2 UR (35) + 1 LAV (1) = 106 F.U.
S: 2 WC (70) + 2 UR (35) + 2 LAV (2) = 107 F.U.
T: 6 WC (125) + 6 UR (63) + 6 LAV (6) = 194 F.U.
610.11 Sizing Systems for Flushometer Tanks. The size of branches and mains serving flushometer tanks shall be consistent with the sizing procedures for flush tank water closets.
610.12 Sizing for Velocity. Water piping systems shall not exceed the maximum velocities listed in this section or Appendix A.
610.12.1 Copper Tube Systems. Maximum velocities in copper and copper alloy tube and fitting systems shall not exceed eight (8) feet per second (fps) (2.4 mps) in cold water and five (5) fps in hot water (1.5 mps).

Except for outside leaders and perforated or open-jointed drain tile, the piping of storm drain systems shall be tested upon completion of the rough piping installation by water or air, except that plastic pipe shall not be tested with air, and proved tight. The Authority Having Jurisdiction shall be permitted to require the removal of any cleanout plugs to ascertain whether the pressure has reached parts of the system. One (1) of the following test methods shall be used:
1109.2.1 Water Test. After piping has been installed, the water test shall be applied to the drainage system, either to the entire system or to sections. If the test is applied to the entire system, all openings in the piping shall be tightly closed except for the highest opening, and the system shall be filled with water to the point of overflow. If the system is tested in sections, each opening shall be tightly plugged except for the highest opening of the section under test, and each section shall be filled with water, but no section shall be tested with less than a ten (10) foot (3,048 mm) head of water. In testing successive sections, not less than the upper ten (10) feet (3,048 mm) of the next preceding section shall be tested so that no joint of pipe in the building (except the uppermost ten (10) feet (3,048 mm) of a roof drainage system, which shall be filled with water to the flood level of the upper most roof drain) shall have been submitted to a test of less than a ten (10) foot (3,048 mm) head of water. The water shall be kept in the system or in the portion under test for not less than fifteen (15) minutes before inspections starts; the system shall than be tight at all points.
1109.2.2 Air Test. The air test shall be made by attaching an air compressor testing apparatus to any suitable opening after closing other inlets and outlets to the system, forcing air into the system until there is a uniform gauge pressure of five (5) psi (34.5 kPa) or sufficient pressure to balance a column of mercury ten (10) inches (254 mm) in height. This pressure shall be held without introduction of additional air for a period of not less than fifteen (15) minutes.
1109.2.3 Exceptions. When circumstances exist that make air and water tests described in Sections 1109.2.1 and 1109.2.2 above impractical, see Section 103.5.3.3.

1216.0 Required Gas Supply.
1216.1 The following regulations, as set forth in this section and in Section 1217.0, Required Gas Piping Size, shall be the standard for the installation of gas piping. Natural gas regulations and tables are based on the use of gas having a specific gravity of sixty-hundredths (0.60), supplied at six (6) to eight (8) inches (152–203 mm) water column pressure at the outlet of the meter or regulator. For undiluted liquefied petroleum gas, gas piping shall be permitted to be sized at eleven (11) inches (279 mm) water column pressure at the outlet of the meter or regulator and specific gravity of one and fifty- hundredths (1.50).
Note: Where gas of a different specific gravity is to be delivered, the serving gas supplier should be contacted for specific gravity conversion factors to use in sizing piping systems from the pipe sizing tables in this chapter.
1216.2 The hourly volume of gas required at each piping outlet shall be taken as not less than the maximum hourly rating as specified by the manufacturer of the appliance or appliances to be connected to each such outlet.
1216.3 Where the gas appliances to be installed have not been definitely specified, Table 12–1 shall be permitted to be used as a reference to estimate requirements of typical appliances.
To obtain the cubic feet per hour (L/sec.) of gas required, divide input of appliances by the average Btu (Watt-hour) heating value per cubic foot (L) of the gas. The average Btu (Watt-hour) per cubic foot (L) of the gas in the area of the installation shall be permitted to be obtained from the serving gas supplier.
1216.4 The size of the supply piping outlet for any gas appliance shall not be less than one-half (½) inch (15 mm).
The minimum size of any piping outlet for a mobile home shall be three-quarters (¾) of an inch (20 mm).
1217.0 Required Gas Piping Size.
1217.1 Pipe Sizing Methods. Where the pipe size is to be determined using any of the methods in Sections 1217.1.1 through 1217.1.3, the diameter of each pipe segment shall be obtained from the pipe-sizing tables in Section 1217.2 or from the sizing equations in Section 1217.3. [NFPA 54:6.1]
1217.1.1 Longest Length Method. The pipe size of each section of gas piping shall be determined using the longest length of piping from the point of delivery to the most re-
mote outlet and the load of the section (See calculation example in Figure 12–2). [NFPA 54:6.1.1]
1217.1.2 Branch Length Method. Pipe shall be sized as follows: [NFPA 54:6.1.2]
1217.1.3 Hybrid Pressure. The pipe size for each section of higher-pressure gas piping shall be determined using the longest length of piping from the point of delivery to the most remote line pressure regulator. The pipe size from the line pressure regulator to each outlet shall be determined using the length of piping from the regulator to the most remote outlet served by the regulator. [NFPA 54:6.1.3]
1217.2 Tables for Sizing Gas-Piping Systems. Tables 12–8 through 12–41 shall be used to size gas piping in conjunction with one (1) of the methods described in Sections 1217.1.1 through 1217.1.3. [NFPA 54:6.2]
1217.3 Sizing Equations. The inside diameter of smooth-wall pipe or tubing shall be determined by the sizing equations 12–1 or 12–2, using the equivalent pipe length determined by Sections 1217.1.1 through 1217.1.3. [NFPA 54:6.4]

1311.0 General Requirements.
1311.1 Oxygen Compatibility. Tubes, valves, fittings, station outlets, and other piping components in medical gas systems shall have been cleaned for oxygen service by the manufacturer prior to installation in accordance with CGA 4.1, Cleaning Equipment for Oxygen Service, except that fittings shall be permitted to be cleaned by a supplier or agency other than the manufacturer. [NFPA 99:5.1.10.1.1]
1311.1.1 Components include but are not limited to containers, valves, valve seats, lubricants, fittings, gaskets, and interconnecting equipment including hose. Easily ignitable materials should be avoided.
Compatibility involves both combustibility and ease of ignition. Materials that burn in air will burn violently in pure oxygen at normal pressure and explosively in pressurized oxygen. Also, many materials that do not burn in air will do so in pure oxygen, particularly under pressure. Metals for containers and piping have to be carefully selected, depending on service conditions. The various steels are acceptable for many applications, but some service conditions can call for other materials (usually copper or its alloys) because of their greater resistance to ignition and lower rate of combustion. Similarly, materials that can be ignited in air have lower ignition energies in oxygen. Many such materials can be ignited by friction at a valve seat, stem packing or by adiabatic compression produced when oxygen at high pressure is rapidly introduced into a system initially at low pressure.
1311.1.2 Materials used in central supply systems shall meet the following requirement [NFPA 99:5.1.3.4.4]:
In those portions of systems intended to handle oxygen or nitrous oxide at gauge pressures of less than three hundred (300) psi (2,070 kPa), material construction shall be compatible with oxygen under the temperatures and pressures to which the components can be exposed in the containment and use of oxygen, nitrous oxide, mixtures of these gases, or mixtures containing more than 23.5 percent oxygen. [NFPA 99:5.1.3.4.4(1), (2)]

1314.2.1 Measure the length of the pipe from the source equipment location to the most remote station inlet⁄outlet on the system.
1314.2.2 In Table 13-6, select the column showing that distance, or the next longer distance if the table does not give the exact length.
1314.2.3 Starting at the most remote outlet⁄inlet, find in the vertical column just selected the medical gas or vacuum demand for that inlet⁄outlet. If the exact figure of demand is not shown, choose the next larger figure below in the column.
1314.2.4 Opposite this demand figure, in the first column at the left in Table 13-6, will be found the correct size of pipe.
1314.2.5 Using this same vertical column, proceed in a similar manner for each section of pipe serving this inlet⁄outlet. For each section of pipe, determine the total gas or vacuum demand supplied by the section, using Table 13-4.

Chapter/Section |
Because of the variable conditions encountered, it is impractical to lay down definite detailed rules of procedure for determining the sizes of water supply pipes in an appendix, which must necessarily be limited in length. For a more adequate understanding of the problems involved, refer to Water-Distributing Systems for Buildings, Report BMS 79 of the National Bureau of Standards; and Plumbing Manual, Report BMS 66, also published by the National Bureau of Standards.
The following is a suggested order of procedure for sizing the water supply system.
A 1.0 Preliminary Information.
A 1.1 Obtain the necessary information regarding the minimum daily service pressure in the area where the building is to be located.
A 1.2 If the building supply is to be metered, obtain information regarding friction loss relative to the rate of flow for meters in the range of sizes likely to be used. Friction-loss data can be obtained from most manufacturers of water meters. Friction losses for disk-type meters shall be permitted to be obtained from Chart A-1.
A 1.3 Obtain all available local information regarding the use of different kinds of pipe with respect both to durability and to decrease in capacity with length of service in the particular water supply.
A 2.0 Demand Load.
A 2.1 Estimate the supply demand for the building main, the principal branches and risers of the system by totaling the fixture units on each, Table A-2, and then by reading the corresponding ordinate from Chart A-2 or A-3, whichever is applicable.
A 2.2 Estimate continuous supply demands in gallons per minute (liters per second) for lawn sprinklers, air conditioners, etc., and add the sum to the total demand for fixtures. The result is the estimated supply demand of the building supply.
A 3.0 Permissible Friction Loss.
A 3.1 Decide what is the desirable minimum residual pressure that shall be maintained at the highest fixture in the supply system. If the highest group of fixtures contains flushometer valves, the residual pressure for the group shall not be less than fifteen (15) psi (103 kPa). For flush tank supplies, the available residual pressure shall not be less than eight (8) psi (55 kPa).
A3.2 Determine the elevation of the highest fixture or group of fixtures above the water (street) main. Multiply this difference in elevation by forty-three hundredths (0.43). The result is the loss in static pressure in psi (pounds per square inch) (kPa).
A3.3 Subtract the sum of loss in static pressure and the residual pressure to be maintained at the highest fixture from the average minimum daily service pressure. The result will be the pressure available for friction loss in the supply pipes, if no water meter is used. If a meter is to be installed, the friction loss in the meter for the estimated maximum demand should also be subtracted from the service pressure to determine the pressure loss available for friction loss in the supply pipes.
A 3.4 Determine the developed length of pipe from the water (street) main to the highest fixture. If close estimate are desired, compute with the aid of Table A-3, the equivalent length of pipe for all fittings in the line from the water (street) main to the highest fixture and add the sum to the developed length. The pressure available for friction loss in pounds per square inch (kPa), divided by the developed lengths of pipe from the water (street) main to the highest fixture, times one hundred (100), will be the average permissible friction loss per one-hundred (100) feet (30,480 mm) length of pipe.
A 4.0 Size of Building Supply.
A 4.1 Knowing the permissible friction loss per one-hundred (100) feet (30,480 mm) of pipe and the total demand, the diameter of the building supply pipe shall be permitted to be obtained from Charts A-4, A-5, A-6, or A-7, whichever is applicable. The diameter of pipe on or next above the coordinate point corresponding to the estimated total demand and the permissible friction loss will be the size needed up to the first branch from the building supply pipe.
A 4.2 If copper tubing or brass pipe is to be used for the supply piping and if the character of the water is such that only slight changes in the hydraulic characteristics may be expected, Chart A-4 shall be permitted to be used.
A 4.3 Chart A-5 should be used for ferrous pipe with only the most favorable water supply in regards to corrosion and caking. If the water is hard or corrosive, Chapter A-6 or A-7 will be applicable. For extremely hard water, it will be advisable to make additional allowances for the reduction of capacity of hot-water lines in service.
A 5.0 Size of Principal Branches and Risers.
A 5.1 The required size of branches and risers shall be permitted to be obtained in the same manner as the building supply, by obtaining the demand load on each branch or riser and using the permissible friction loss computed in Section A 3.0.
A 5.2 Fixture branches to the building supply, if they are sized for the same permissible friction loss per one-hundred (100) feet (30,480 mm) of pipe as the branches and risers to the highest level in the building, may lead to in adequate water supply to the upper floor of a building. This may be controlled by (1) selecting the sizes of pipe
for the different branches so that the total friction loss in each lower branch is approximately equal to the total loss in the riser, including both friction loss and loss in static pressure; (2) throttling each such branch by means of a valve until the preceding balance is obtained; (3) increasing the size of the building supply and risers above the minimum required to meet the maximum permissible friction loss.
A 5.3 The size of branches and mains serving flushometer tanks shall be consistent with sizing procedures for flush tank water closets.
A 6.0 General.
A 6.1 Velocities shall not exceed ten (10) feet/second (3.0m/sec.) or the maximum values given in the appropriate Installation Standard, except as otherwise approved by the Authority Having Jurisdiction.
A 6.2 If a pressure-reducing valve is used in the building supply, the developed length of supply piping and the permissible friction loss should be computed from the building side of the valve.
A 6.3 The allowances in Table A-3 for fittings are based on non-recessed threaded fittings. For recessed threaded fittings and streamlined soldered fittings, one-half (½) of the allowances given in the table will be ample.
A 7.0 Example.
A 7.1 Assume an office building of four (4) stories and basement; pressure on the building side of the pressure-reducing valve of fifty-five (55) psi (379 kPa) (after an allowance for reduced pressure falloff at peak demand); an elevation of highest fixture above the pressure-reducing valve of forty-five (45) feet (13,716 mm); a developed length of pipe from the pressure-reducing valve to the most distant fixture of two-hundred (200) feet (60,960 mm); and fixtures to be installed with flush valves for water closets and stall urinals as follows:
If the pipe material and water supply are such that Chart A-5 applies, the required diameter of the building supply is three and one-half (3½) inches (88.9 mm) and the required diameter of the branch to the hot-water heater is one and one-half (1½) inches (40 mm).
The sizes of the various branches and risers shall be permitted to be determined in the same manner as the size of the building supply or the branch to the hot-water system, by estimating the demand for the riser or branch from Chart A-2 or A-3 and applying the total demand estimate from the branch, riser, or section thereof to the appropriate flowchart.

Total | 1,365 | 252 gpm (15.8 L/s) | 154 | 55 gpm (3.4 L/s) |
Allowing for 15 psi (103.4 kPa) at the highest fixture under the maximum demand of 252 gallons per minute (15.8 L/sec.), the pressure available for friction loss is found by the following:
55 – [15 + (45 x 0.43)] = 20.65 psi
Metric: 379 – [103.4 + (13.7 x 9.8)] = 142.3 kPa
The allowable friction loss per 100 feet (30.4 m) of pipe is therefore:
100 x 20.65 ÷ 200 = 10.32 psi
Metric: 30.4 x 142.3 ÷ 60.8 = 71.1 kPa

B 1.0 Combination waste and vent systems, as outlined in Section 910.0 of this code, cover the horizontal wet venting of a series of traps by means of a common waste and vent pipe. Pipe sizes at least two (2) pipe sizes larger than those required for a conventional system are designed to maintain a wetted perimeter or flow line low enough in the waste pipe to allow adequate air movement in the upper portion, thus balancing the system. Sinks, lavatories, and other fixtures that rough in above the floor, should not be permitted on a combination waste and vent system, which, at best, is merely an expedient designed to be used in locations where it would be structurally impractical to provide venting in the conventional manner.
Combination waste and vent systems are intended primarily for extensive floor or shower drain installations where separate venting is not practical, for floor sinks in markets, demonstration or work tables in school buildings, or for similar applications where the fixtures are not adjacent to walls or partitions. Due to its oversize characteristics, such a waste system is not self-scouring and, consequently, care should be the location of cleanouts. In view of its grease-producing potential, restaurant kitchen equipment should not be connected to a combination waste and vent system.
B 2.0 Caution must be exercised to exclude appurtenances delivering large quantities or surges of water (such as pumps, sand interceptors, etc.) from combination waste and vent systems in order that adequate venting will be maintained. Small fixtures with a waste-producing potential of less than seven and one-half (7½) gallons per minute (28.4 L/min.) shall be permitted to be safely assigned a loading value of one (1) unit. Long runs should be laid at the minimum permissible slope in order to keep tailpieces as short as possible. Tailpieces should not exceed two (2) feet (610 mm) in length, which may necessitate slopes up to forty-five (45) degrees (0.79 rad) (see definition of horizontal pipe) on some branches.
B 3.0 It is essential that the pneumatics of such a system be properly engineered, as the air pressure within the line must at all times balance that of outside atmosphere in order to prevent either trap seal loss or air locking between traps. Long mains shall be provided with additional relief vents located at intervals not exceeding one-hundred (100) feet (30,480 mm). Each such relief vent should equal at least one-half(½) of the inside cross-sectional area of the drain pipe served.
B 4.0 Trap sizes are required to be equivalent to the branches they serve (two (2) pipe sizes larger than normal), and tailpieces between fixtures or floor drains and such traps should be reduced to normal size.
B 5.0 Duplicate layout drawings of each such proposed piping system must be presented to the Authority Having Jurisdiction and approval obtained before any installation is made. Complicated layouts should be checked by qualified personnel.
B 5.1 Example of Sizing.
A floor drain normally requires a two (2) inch (50 mm) trap and waste. On a combination waste and vent system, both trap and waste must be increased two (2) pipe sizes (through ½"and 3") (65 mm and 80 mm), which would make the trap three (3) inches (80 mm). Pipe sizes recognized for this purpose are 2 in., 2½ in., 3 in., 3½ in., 4 in., 4½ in., 5 in., 6 in., etc. (50 mm, 65 mm, 80 mm, 90 mm, 100 mm, 115 mm, 125 mm, 150 mm, etc). The tail piece between the floor drain and its trap should be two (2) inches (50 mm) (or normal size) to ensure that the amount of wastewater entering the trap only partially fills the waste branch. A three (3) inch (80 mm) floor drain would thus require a four (4) inch (100 mm) trap, a four (4) inch (100 mm) floor drain, and five (5) inch (125 mm) trap, etc., for the reasons previously stated.
WHEN IN DOUBT, CHECK WITH YOUR LOCAL Authority Having Jurisdiction.

D 1.0 Roof Drainage.
The rainfall rates in Table D-1 should be used for design unless higher values are established locally.
D 2.0 Sizing by Flow Rate.
Storm drainage systems can be sized by storm water flow rates, using the appropriate GPM/square foot of rainfall listed in Table D-1 for the local area. Multiplying the listed GPM/square foot by the roof area being drained by each inlet (in square feet) produces the gallons per minute (GPM) of required flow for sizing each drain inlet. The flow rates (GPM) can then be added to determine the flows in each section of the drainage system. Required pipe sizes for various flow rates (GPM) are listed in Table 11-1 and Table 11-2.
D 3.0 Sizing by Roof Area.
Storm drainage systems can be sized using the roof area served by each section of the drainage system. Maximum allowable roof areas with various rainfall rates are listed in Table 11-1 and Table 11-2, along with the required pipe sizes. Using this method, it may be necessary to interpolate between two listed rainfall rate columns (inches per hour). To determine the allowable roof area for a listed pipe size at a listed slope, divide the allowable square feet of roof for a one (1) in./hr. (25.4 mm/h) rainfall rate by the listed rainfall rate for the local area. For example, the allowable roof area for a six (6) inch (150 mm) drain at one-eighth (1⁄8) inch (3.2 mm) slope with a rainfall rate of 3.2 inches (81 mm/h) is 21,400/3.2 = 6,688 square feet (621.3 m2).
D 4.0 Capacity of Rectangular Scuppers.
Table D-2 lists the discharge capacity of rectangular roof scuppers of various widths with various heads of water. The maximum allowable level of water on the roof should be obtained from the structural engineer, based on the design of the roof.

G 1.0 Graywater Systems (General).
G 2.0 Definitions.
Graywater is untreated waste water which has not come into contact with toilet waste. Graywater includes used water from bathtubs, showers, bathroom wash basins, clothes washing machines and laundry tubs or an equivalent discharge as approved by the Administrative Authority. It does not include waste water from kitchen sinks, photo lab sinks, dishwashers or laundry water from soiled diapers.
Surfacing of graywater means the ponding, running off or other release of graywater from the land surface.
G 3.0 Permit.
It shall be unlawful for any person to construct, install or alter, or cause to be constructed, installed or altered, any graywater system in a building or on a premises without first obtaining a permit to do such work from the Administrative Authority.
G 4.0 Drawings and Specifications.
The Administrative Authority may require any or all of the following information to be included with or in the plot plan before a permit is issued for a graywater system:
G 5.0 Inspection and Testing.
G 6.0 Procedure for Estimating Graywater Discharge.
First bedroom | 2 occupants |
Each additional bedroom | 1 occupant |
Showers, bathtubs, and wash basins | 25 GPD/occupant |
Laundry | 15 GPD/occupant |
The Administrative Authority may utilize the graywater discharge procedure listed below, water use records or other documentation to estimate graywater discharge:
The graywater system shall be designed to distribute the total amount of estimated graywater discharged daily.
G 7.0 Required Area of Subsurface Irrigation.
Each irrigation zone shall have a minimum effective irrigation area for the type of soil and infiltration rate to distribute all graywater produced daily, pursuant to Section G 6.0, without surfacing. The required irrigation area shall be based on the estimated graywater discharge, pursuant to Section G 6.0 of this Appendix, size of surge tank, or a method determined by the Administrative Authority.
If the mini-leachfield irrigation system is used, the required square footage shall be determined from Table G-2, or equivalent, for the type of soil found in the excavation. The area of the irrigation field shall be equal to the aggregate length of the perforated pipe sections within the irrigation zone times the width of the proposed mini-leachfield trench.
No irrigation point shall be within 5 vertical feet (1524 mm) of highest known seasonal groundwater nor where graywater may contaminate the ground water or ocean water. The applicant shall supply evidence of ground water depth to the satisfaction of the Administrative Authority.

2.2 Type of Joints.
2.2.1 General Information.
Copper tube and fittings may be joined in a number of ways, depending on the purpose of the system. Soldering and brazing with capillary fittings are the methods used most.
The American Welding Society (AWS) defines soldering as a joining process which takes place below 840°F (449°C) but below the melting point of the base metals. In actual practice for copper systems, most soldering is done at temperatures from about 350°F (177°C) to 550°F (288°C), while most brazing is done at temperatures ranging from 1100°C (593°C) to 1500°F (816°C). The choice between soldering or brazing will generally depend on operating conditions. Solder joints are generally used where the service temperature does not exceed 250°F (121°C), while brazed joints are used where greater tensile strength is required to resist vibration, or pressure or temperature cycling, or where system temperatures are as high as 350°F (177°C). Although brazed joints offer higher joint strength in general, the annealing of the tube and fitting which results from the higher heat used in the brazing process can cause the rated pressure of the system to be less than that of a soldered joint. This fact should also be considered in choosing which joining process to use.
Mechanical joints are used frequently for use some underground connections, for joints where the use of heat is impractical and for joints that may have to be disconnected from time to time. [UPC 316.1]
2.2.2 Fittings for Soldered, Brazed, and Mechanical Joints.
Cast fittings are available in all standard tube sizes and in a wide variety of types to cover needs for plumbing. They can be either soldered or brazed, although brazing cast fittings requires care. Wrought copper pressure fittings are also available over a wide range of sizes and types. These, too, can be joined by either soldering or brazing and wrought fittings are prefferred where brazing is the joining method. Otherwise, the choice between cast and wrought fittings is largely a matter of the user's preference and availability. According to the American Welding Society, the strength of a brazed joint will meet or exceed that of the tube and fitting being joined when the joint overlap and the depth of the filler metal penetration is a minimum of three times the thickness of the thinner base metals (tube or fitting) and a well-developed fillet (cap) is present. The strength of a brazed copper tube joint does nor vary much with different filler metals but depends on maintaining the proper clearance between the outside of the tube and the socket (cup) of the fitting. Copper tube and solder-type pressure fittings are accurately made for each other, and the tolerances permitted for each assure the capillary space will be within the limits necessary for a joint of satisfactory strength. However, the depths of the socket are considerable deeper than the three times required by AWS. Three are standards available for the manufacture of fittings made specifically for brazing, these include ASME B 16.50 and MSS SP 73. When fittings are made to these standards, they cannot be soldered. They must be brazed.
2.2.2.1 Mechanical Joints.
Flared-tube fittings provide metal-to-metal contact similar to ground joint unions; both can be easliy taken apart and reassembled. Grooved end mechanical fittings are also available in sizes 2-inches to 6-inches. Mechanical joint fittings are especially useful where residual water cannot be removed from the tube and soldering is difficult. Mechanical joints may be required where a fire hazard exists and the use of a torch to make soldered or brazed joints is not allowed. Also, soldering under wet conditions can be very difficult and mechanical joints may be preffered under such circumstances. [UPC 316.0]
2.2.3 Solders.
Most solders referenced in ASTM B 32 can be used to join copper tube and fittings in potable water systems.
Note: Users of the Uniform Plumbing Code are reminded that provisions of the Federal Safe Drinking Water Act of 1986 (SDWA), which all must obey, forbid the use of solder which contains in excess of 0.2% of lead, in potable water systems. The provisions of the act are in corporated in all ordiances, statues, state and municipal regulations by reference and by operation of law. [UPC 316.0]
The selection of a solder depends on the operating pressure and temperature of the system. Consideration should also be given to the stresses on the joint caused by thermal expansion and contraction. However, stresses due to temperature changes should not be significant in two commonly encountered cases: when tube lengths are short, or when expansion loops are used in long tube runs.
Solder is generally used in wire form, but paste-type solders are also available. These are finely granulated solders in suspension in a paste flux. These solder/flux pastes must meet the requirements of ASTM B 813. When using paste-type solders, observe these four rules:
Solders are available that contain small amounts of silver or other additives to impart special properties. Such solders may require special fluxes. The manufacturer's recommendations should be consulted regarding proper procedures and fluxes for such solders and about the expected properties.
2.2.4 Soldering Flux.
The functions of the soldering flux are to remove residual tracers of oxides, to promote wetting and to protect the surfaces to be soldered from oxidation during heating. The flux should be applied to clean surfaces and only enough should be used to lightly coat the areas to be joined.
An oxide flim may reform quickly on copper after it has been cleaned. Therefore, the flux should be applied as soon as possible after cleaning.
Careless workmanship, especially during flux applications, can result in corrosion of the tube long after the system has been installed. If excessive flux is used, the residue inside the tube can cause corrosion. In an extreme case, such residual flux can actually lead to perforation through the tube wall causing leakage. To guard against this danger, it is important (1) to choose a flux that is manufactured to ASTM B 813, and (2) to use only the minimum amount actually needed to make the joint.
2.3 Solder Joints.
2.3.1Soldering and brazing both involve basic steps, based on ASTM Standard Practice B 828, which must be executed with care and craftsmanship.
The steps are:
Each step contributes to a strong, dependable joint.
2.3.2 Measuring.
Measuring the length of each tube segment must be accurate. Inaccuracy can compromise joint quality. If the tube is too short it will not reach all the way into the socket of the fitting and a proper joint cannot be made. If the tube segment is too long there is a danger of cocking the tube in the fitting and putting strain on the system which could affect service life.
2.3.3 Cutting.
Once the tube is measured, it can be cut. Cutting can be accomplished in a number of different ways to produce a satisfactory square end. The tube can be cut with a disc-type tube cutter, a hacksaw, an abrasive wheel, or with a stationary or portable bandsaw. Care must be taken that the tube is not deformed while being cut. Regardless of the method, the cut must be square with the run of the tube so that the tube will seat properly in the fitting socket.
2.3.4 Reaming.
All pipe and tube shall be reamed to the full I.D. of the pipe and tube to remove the small burr created by the cutting operation. If this rough, inside edge is not removed erosion-corrosion may occur due to localized turbulence and high velocity.
Tools used to ream tube ends include the reaming blade on the tube cutter, half-round or round files, a pocket knife, or a suitable deburring tool. With annealed tube, care must be taken not to deform the tube end by applying too much pressure. Both the inside and the outside of the tube may require removal of the burr, especially in large diameters.
2.3.5 Cleaning.
The removal of all oxides and surfaces soil is crucial if filler metal is to flow properly into the joint. Failure to remove them can interfere with capillary action and may lessen the strength of the joint and cause failure.
Mechanical cleaning is a simple operation. The end of the tube should be lightly abraded using sand cloth or nylon abrasive pads for a distance only slightly more than the depth of the fitting socket. The socket of the fitting should also be cleaned using sand cloth, abrasive pads, or a properly sized fitting brush.
Copper is a relatively soft metal. If too much material is removed, a loose fit will result and interfere with satisfactory capillary action in making the joint. The capillary space between tube and fitting is approximately 0.004 inch (0.10 mm). Solder or brazing filler metal can fill this gap by capillary action. This spacing is critical for the filler metal to flow into the gap and form a strong joint.
Surfaces once cleaned should not be touched with bare hands or oily gloves. Skin oils, lubricating oils, and grease impair filler metal flow and wetting.
2.3.6 Fluxing.
Stir the flux before use. Flux will dissolve and remove traces of oxide from the cleaned surfaces to be joined, protect the cleaned surfaces from reoxidation during heating, and promote wetting of the surfaces by the solder. A thin, even coating of flux should be applied with fingers. Chemicals in the flux can be harmful if carried to the eyes, mouth, or open cuts.
2.3.7 Assembly and Support.
After both tube and fitting surfaces are properly fluxed, they should be assembled, making sure the tube seats against the base of the fitting socket. A slight twisting motion ensures even distribution by the flux. Remove any excess flux. Care must be taken to assure that the tube and fittings are properly supported to ensure a uniform capillary space around the entire circumference of the joint. Uniformity of capillary space will ensure good filler metal penetration if the guidelines of successful joint making are followed. Excessive joint clearance can cause the filler metal to crack under stress or vibration.
The joint is now ready for soldering. Joints prepared and ready for soldering should be completed the same day and not left unfinished overnight.
2.3.8 Heating.
WARNING: When dealing with an open flame, high temperatures, and flammable gases, safety precautions must be observed as described in the ANSI/ASC Z49.1 Standard.
Heat is generally applied using an air/fuel torch. Such torches use acetylene or an LP gas. Electric resistance tools can also be used.
Begin heating with the flame perpendicular to the tube on the bottom. The copper tube conducts the initial heat into the fitting socket for even distribution of heat in the joint area. The extent of this preheating depends upon the size of the joint. Experience will indicate the amount of time needed. Preheating of the assembly should include the entire circumference of the tube in order to bring the entire assembly up to a suitable preheat condition. However, for joints in the horizontal position, avoid directly preheating the top of the joint to avoid burning the soldering flux. The natural tendency of heat to rise will ensure adequate preheat of the top of the assembly. Next, move the flame onto the fitting socket. Sweep the flame alternately from the fitting socket back onto the tube a distance equal to the depth of the fitting socket. Touch the solder to the joint. If the solder does not melt, remove it and continue the heating process. Be careful not to overheat or to direct the flame into the fitting cup. This could cause the flux to burn and destory its effectiveness. When the solder begins to melt, the heat should be directed to the base of the cup to aid capillary action in drawing the molten solder into the fitting socket to wards the heat source.
2.3.9 Applying the Filler Metal.
For joints in the horizontal position, start applying the solder slightly off-center at the bottom of the joint. When the solder metal begins to melt from the heat of the tube and fitting do not use the torch to melt the solder; push the solder straight into the joint while keeping the torch at the base of the fitting socket and slightly ahead of the point of application of the solder. Continue this technique across the bottom of the fitting and up the side to the top of the fitting. Return to the beginning, overlapping slightly by re-melting the solder at the point and proceed up the other side to the top, again overlapping slightly.
For joints in the vertical position, a similar sequence of overlapping passes should be made, starting wherever is convenient. Molten solder will be drawn into the joint by capillary action regardless of whether the solder is being fed upward, downward or horizontally. IMPORTANT: Always remember to let the heat lead the alloy. Do not apply the filler metal in front of the heat.
2.3.10 Cooling and Cleaning.
After the joint has been completed, natural cooling is best. Shock cooling with water may cause
unnecessary stress on the joint and result in eventual failure. When cool, clean off any remaining flux with a wet rag.
2.3.11 Testing.
Test all completed assemblies for joint integrity following the procedures described in the body of this code. Completed systems should be flushed to remove excess flux and debris as soon as possible after completion.
2.4 Brazed Joints.
2.4.1 Brazing is another commonly used method for joining copper tube. Making brazed joints is similar to making soldered joints with respect to measuring, cutting, reaming, cleaning, assembly, and support. And as in soldering, the brazing filler metal is melted by the heat of the tube and fitting and drawn into the joint by capillary action.
The major differences between soldering and brazing are the:
2.4.2 Brazing Flux.
The fluxes used for brazing copper joints are different in composition from soldering fluxes. The two types cannot be used interchangeably. Unlike soldering fluxes, brazing fluxes are water based. Similar to soldering fluxes, brazing fluxes dissolve and remove residual oxide from the metal surfaces, protect the metal from reoxidation during heating and promote wetting of the surfaces to be joined by the brazing filler metal.
Fluxes also provide the craftsman with an indication of temperature. Application of the flux is the same as when soldering. If the outside of the fitting and the heat-affected area of the tube are covered with flux (in addition to the end of the tube and the cup), oxidation will be prevented and the apperance of the joint will be greatly improved.
2.4.3 Brazing Filler Metals.
Brazing filler metals suitable for joining copper tube systems are of two classes. Classified according to their components, they are: BCuP (Brazing-Copper-Phosphorus) and BAg (Brazing-Sliver).
BCuP filler metals are prefferred for joining copper tube and fittings if codes and construction specifications allow it. The phosphorus in them acts as a fluxing agent and the lower percentage of sliver makes them relatively low cost. When using copper tube, wrought copper fittings, and BCuP brazing filler metal, fluxing is optional. However, when cast fittings are brazed, flux must be used.
2.4.4 Heating.
WARNING: When dealing with an open flame, high temperatures, and flammable gases, safety precautions must be observed as described in the ANSI/ASC Z49.1 Standard. Oxy/fuel torches are generally used for brazing because of their higher temperatures. However, recent innovations in tip design make air/fuel torches useful for brazing on a wide range of sizes for brazing.
The heating operation is the same as for soldering. Heat the tube first, beginning about one inch from the edge of the fitting, sweeping, the flame around the tube in short strokes at right angles to the axis of the tube. It is very important that the flame be in motion and not remain on any one point long enough to damage the tube. Switch the flame to the fitting at the base of the fitting socket. Heat uniformly, sweeping the flame from the fitting to the tube. Avoid excessive heating of case fittings or they may crack.
2.4.5 Applying Brazing Filler Metal.
Apply the brazing filler metal at the point where the tube enters the socket of the fitting. When the proper temperature is reached, the filler metal will flow readily into the space between the tube and fitting socket, drawn in by the natural force of capillary action.
Keep the flame away from the filler metal itself as it is fed into the joint. The temperature of the tube and fitting at the joint should be high enough to melt the filler metal. Keep both the tube and fitting heated by moving the flame back and forth from one to the other as the filler metal is drawn into the joint.
When the joint is properly made the filler metal will be drawn into the fitting socket by capillary action, and a continuous fillet (cap) of filler metal will be visible completely around the joint. To aid in the development of this fillet during brazing, the flame should be kept slightly ahead of the pint of filler metal application.
When brazing horizontal joints, it is preferable to first apply the filler metal slightly off-center of the bottom of the joint, proceeding across the bottom of the joint and continuing up the side to the top of the joint. The return to the beginning point, overlapping slightly. This procedure is identical to that used for soldering. Also, similar to the soldering process, make sure the operations overlap.
On vertical joints, it is immaterial where the joint is made. If the opening of the fitting socket is pointing down, care should be taken to avoid over-heating the tube, as this may cause the brazing filler metal to run down the outside of the tube.
If the filler metal fails to flow, or has the tendency to ball-up, it indicates either that there is oxide on
the surfaces being joined or that the parts to be joined are not hot enough. If the filler metal refuses to enter the joint, the fitting cup is not hot enough. Most poorly made braze joints result from either the tube or the fitting not being hot enough. If filler metal tends to flow over the outside of either part of the joint, it indicates that part is overheated in comparison to the other. When the joint is completed, a continuous fillet should be visible completely around the joint.
Larger diameter tube is more difficult to heat to the desired temperature. The use of a heating tip or rosebud may be necessary to maintain the proper temperature over the area being brazed. Once total heat control is attained, follow the same procedures used for smaller tube.
2.4.6 Cooling and Cleaning.
When the brazed joint is finished, allow it to cool naturally. Flux residues and some oxides formed by heating can be removed by washing with hot water and brushing with a stainless steel wire brush.
2.4.7 Testing.
Test all completed assembles for joint integrity following the procedures described in the body of this code. Completed systems should be flushed to remove excess flux and debris as soon as possible after completion.
2.4.8 Purging.
Some installations, such as medical gas, high-purity gas, and ACR systems, require the use of an inert gas during the brazing process. The purge gas displaces oxygen from the interior of the system while it is being subjected to the high temperatures of brazing and therefore eliminates the possibility of oxide formation on the interior of the tube surface.
2.5 Flared Joints.
2.5.1 Flared Joints with Impact Flaring Tools.
Step 1 Cut the tube to the required length.
Step 2 Remove all burrs. This is very important to assure metal-to-metal contact.
Step 3 Soft temper tube, if deformed, should be brought back to roundness with a sizing tool. This tool consists of a plug and sizing ring.
Step 4 Slip the coupling nut over the end of the tube.
Step 5 Insert flaring tool into the tube end.
Step 6 Drive the flaring tool by hammer strokes, expanding the end of the tube to the desired flare. This requires a few moderately light strokes.
Step 7 Assemble the joint by placing the fitting squarely against the flare. Engage the coupling nut with the fitting threads. Tighten with two wrenches, one on the nut and one on the fitting.
2.5.2 Flared Joints with Screw-Type Flaring Tools.
Steps 1-4 Same as for impact flaring previously described.
Step 5 Clamp the tube in the flaring block so that the end of the tube is slightly above the face of the block.
Step 6 Place the yoke of the flaring tool on the block so that the beveled end of the compressor cone is over the tube end.
Step 7 Turn the compressor screw down firmly, forming the flare between the chamber in the flaring block and the beveled compressor cone.
Step 8 Remove the flaring tool. The joint can now be assembled as in Step 6 for impact flaring.
2.6 Sizing, Velocity.
To avoid excess system noise and the possibility of erosion-corrosion, flow through copper tube systems should not exceed velocities of 8 feet per second for cold water and 5 feet per second in hot water up to approximately 140°F (60°C) [UPC 610.0]
In systems where water temperatures routinely exceed 140°F (60°C), lower velocities such as 2 to 3 feet per second should not be exceeded. In addition, where ½-inch and smaller tube sizes are used, to guard against localized high velocity turbulence due to possible faulty workmanship (e.g. burrs at tube ends which were not properly removed) or unusually numerous, abrupt changes in flow direction, lower velocities should be considered.
Due to constant circulation and elevated water temperatures, particular attention should be paid to velocities in circulation hot water systems. Both the supply and return piping should be sized such that the maximum velocity does not exceed the above recommendations. Care should be taken to ensure that the circulating pump is not oversized and the return piping is not undersized, both common occurrences in installed copper piping systems.
3.0 GENERAL INFORMATION.
3.1 It is not possible to cover all the variables of a plumbing system; however, the following information may prove helpful:
Expansion Loops – Copper tube, like all piping materials, expands and contracts with temperature changes. Therefore, in a copper tube system subjected to excessive temperature changes, the line tends to buckle or bend when it expands unless compensation is built into the system. Severe stresses on the joints may also occur. Such stresses, buckles, or bends are prevented by the use of expansion
joints or by installing offsets, “U” bends, coil loops, or similar arrangements in the tube assembly. These specially shaped tube segments take up expansion and contraction without excessive stress. The expansion of a length of copper tube may be calculated from the formula:
Temperature Rise (°F) × Length (feet) × 12 (inches per foot) × Expansion Coefficient (in. per in. per °F) = Expansion (inches), or
Temperature Rise (°C) × Length (meter) × 1000 (mm per meter) × Expansion Coefficient (mm per mm per °C) = Expansion (mm).
Calculations for expansion and contraction should be based on the average coefficient of expansion of copper, which is 0.0000094 per °F (1.692 × 10-5 per °C), between 70°F (21°C) and 212°F (100°C). For example, the expansion of each 100 feet (3048 mm) of length of any size tube heated from room temperature (70°F) (21°C) to 170°F (77°C) (a 100°F (38°C) rise) is 1.128 inches (28.7 mm).
100° × 100 ft. × 12 in./ft. × 0.0000094 in./in./°F = 1.128 in., or
55.6° × 30.48 m × 1000 mm/m × 1.692 × 10-5 mm/mm/°C = 28.7 mm
3.2 Tube Supports - See Table 3-2 and Section 314.0 in the Uniform Plumbing Code.
3.3 Bending.
3.3.1 Copper tube, properly bent, will not collapse on the outside of the bend and will not buckle on the inside of the bend. Tests demonstrate that the bursting strength of a bend copper tube can be greater than it was before bending. Because copper is readily formed, expansion loops and other bends necessary in an assembly are quickly and simply made if the proper method and equipment are used. Simple hand tools employing mandrels, dies, forms, and fillers, or power-operated bending machines are used.
Both annealed tube and bending-temper tube can be bent with hand benders. The proper size bender for each size tube must be used. Usually the size of the tool corresponds to the nominal outside diameter of the tube, not the standard tube size. For a guide to the typical bend radii, see the following bending guide for copper tube.

Length of run – 60 feet (18,288 mm) from chart, read 2.010 inches (51 mm) linear expansion that must be provided for.
2.5.2.2 Handling (to maintain effectiveness). Solvent cement containers no larger than 1 gallon (3.8 liters) should be used in the field (to avoid thickening due to evaporations). Keep container closed and in the shade when not in use. Keep application submerged in solvent cement between application. When solvent cement becomes thicker, THROW IT AWAY. Solvent cement shall NOT be thinned.
2.5.2.3 Size of Applicator. Applicator should be about one half the pipe diameter. Do not use small applicator on large pipes. Ordinary pure bristle paint brust or applicators furnished with product are satisfactory.
2.5.2.4 Application. Solvent cement shall be applied deliberately, but without delay (two people may be needed to make large joints). Use special care when temperature is over 100°F (38°C) or humidity is over 60%.
2.5.3 SAFETY REQUIREMENTS AND PRECAUTIONS.
2.5.3.1 General. Solvents contained in ABS plastic pipe cements are classified as airborne contaminants and flammable and combustible liquids. Precautions listed in this appendix should be followed to avoid injury to personnel and the hazard of fire.
2.5.3.2 Safety Precautions. Prolonged breathing of solvent vapors should be avoided. When pipe and fittings are being joined in partially enclosed areas, a ventilating device should be used in such a manner to minimize the entry of vapors into the breathing areas.
2.5.3.3 Solvent cement should be kept away from all sources of ignition, heat, sparks and open flame.
2.5.3.4 Containers for Solvent cements should be kept tightly closed except when the cement is being used.
2.5.3.5 All rags and other materials used for mopping up spills should be kept in a safety waste receptacle which should be emptied daily.
2.5.3.6 Most of the solvents used in ABS pipe cements can be considered eye irritants and contact with the eye should be avoided for it may cause eye injury. Proper eye protection and the use of chemical goggles or face shields is advisable where the possibility of splashing exists in handling solvent cements. In case of eye contact, flush with plenty of water for 15 minutes and call a physician immediately.
2.5.3.7 Repeated contact with the skin should be avoided. Proper gloves impervious to and unaffected by the solvents should be worn when frequent contact
with the skin is likely. Application of the solvents or solvent cements with rags and bare hand is not recommended. Brushes and other suitable applicators can be used effectively for applying the solvent cement, thus avoiding skin contact. In the event of excessive contact, remove contaminated clothing and wash skin with soap and water.
Step 1 Cut pipe square with hand saw and miter box, mechanical cut-off saw, or tube cutter designed for plastic.
Step 2 Ream inside and chamfer outside of pipe (to eliminate all burrs).
Step 3 Clean all dirt, moisture, and grease from pipe and socket. Use a clean, dry rag.
Step 4 Check dry fit of pipe in fitting. Pipe should enter fitting socket from 1/3 to ¾ depth of socket.
Step 5 Apply a light coat of ABS solvent cement to inside of socket using straight outward strokes (to keep excess solvent out of socket). This is also to prevent solvent cement damage to pipe. For loose fits, apply a second coat of solvent cement. Time is important at this stage. See Section 2.5.2.4.
Step 6 While both the inside socket surface and the outside surface of the pipe are SOFT and WET with solvent cement, forcefully bottom the pipe in the socket, giving the pipe a one-quarter turn, if possible. The pipe must go to the bottom of the socket.
Step 7 Hold the joint together until tight (partial set).
Step 8 Wipe excess cement from the pipe. A properly made joint will normally show a bead around its entire perimeter. Any gaps may indicate insufficient cement or the use of light bodied cement on larger diameters where heavy bodied cement should have been used.
Step 9 The system shall not be tested until the joints have cured (set) at least as long as recommended by the manufacturer.
2.5.4 Threaded Joints.
Threads on iron pipe size (IPS) pipe and fittings shall be standards listed in Table 14-1. Threads on tubing shall be approved types. Threads on plastic pipe shall be factory cut or molded. Threaded plastic pipe shall be Schedule 80 minimum wall thickness. Tubing threads shall conform to fine tubing thread standards. When a pipe joint material is used, it shall be applied only on male threads and such materials shall be approved types, insoluble in water and nontoxic. Cleanout plugs and caps shall be lubricated with water-in-soluble, non-bardening material or tape. Only listed thread tape or thread lubricants and sealants specifically intended for use with plastics shall be used on plastic threads. Conventional pipe thread compounds, putty, linseed oil base products, and unknown lubricants and sealants shall not be used on plastic threads. [UPC 316.1.1]
2.5.5 Special Joints.
2.5.5.1 Plastic Pipe to Other Materials.
When connecting plastic pipe to other types of piping, use only listed fittings and adapters, designed for the specific transition intended. [UPC 316.2.3]

2.6.2 SAFETY REQUIREMENTS AND PRECAUTIONS1
2.6.2.1 General. Solvents contained in PVC plastic pipe cements are classified as airborne contaminants and flammable and combustible liquids. Precautions listed in this appendix should be followed to avoid injury to personnel and the hazard of fire.
2.6.2.2 Safety Precautions. Prolonged breathing of solvent vapors should be avoided. When pipe and fittings are being joined in partially enclosed areas, a ventilating device should be used in such a manner to minimize the entry of vapors into the breathing areas.
2.6.2.3 Solvent cements should be kept away from all sources of ignition, heat, sparks, and open flame.
2.6.2.4 Containers for solvent cements should be kept tightly closed except when the cement is being used.
2.6.2.5 All rags and other materials used for mopping up spills should be kept in a safety waste receptacle which should be emptied daily.
2.6.2.6 Most of the solvents used in PVC pipe cements can be considered eye irritants and contact with the eye should be avoided for it may cause eye injury. Proper eye protection and the use of chemical goggles or face shields is advisable where the possibility of splashing exists in handling solvent cements. In case of eye contact, flush with plenty of water for 15 minutes and call a physician immediately.
2.6.2.7 Repeated contact with the skin should be avoided.
Proper gloves impervious to and unaffected by the solvents should be worn when frequent contact with the skin is likely. Application of the solvents or solvent cements with rags and bare hands is not recommended. Brushes and other suitable applicators can be used effectively for applying the solvent cement, thus avoiding skin contact. In the event of excessive contact, remove contaminated clothing and wash skin with soap and water.
CAUTION: Primers are toxic. Don't allow them to touch skin. Suitable gloves are advised.
Step 1. Cut pipe square with hand saw and miter box, mechanical cut-off saw or tube cutter designed for plastic.
Step 2. Ream and chamfer pipe (to eliminate sharp edges, beads, and all burrs).
Step 3. Clean all dirt, moisture and grease from pipe and fitting socket. Use a clean, dry rag.
Step 4. Check dry fit of pipe in fitting. Pipe should enter fitting socket from 1/3 to ¾ depth of socket.
Step 5. Soften inside socket surface by applying an aggressive primer.
Step 6. Soften mating outside surface of pipe to depth of socket by applying a liberal coat of the (aggressive) primer. Be sure entire surface is softened.
Step 7. Again coat inside socket surface with the (aggressive) primer. Then, without delay, apply solvent cement liberally to outside of pipe. Use more than enough to fill any gaps.
Step 8. Apply a light coat of PVC solvent cement to inside of socket using straight outward strokes (to keep excess solvent out of socket). This is also to prevent solvent cement damage to pipe. For loose fits, apply a second coat of solvent cement. Time is important at this stage. See Section 2.6.1.5.
Step 9. While both the inside socket surface and the outside surface of the pipe are SOFT and WET with solvent cement, forcefully bottom the pipe in the socket, giving the pipe a one-quarter turn, if possible. The pipe must go to the bottom of the socket.
Step 10. Hold the joint together until tight.
Step 11. Wipe excess cement from the pipe. A properly made joint will normally show a bead around its entire perimeter. Any gaps may indicate insufficient cement or the use of light bodied cement on larger diameters where heavy bodied cement should have been used.
Step 12. Do not disturb joint for the following periods: 30 minutes minimum at 60°F to 100°F (16°C to 38°C).
1 hour minimum at 40°F to 60°F (4°C to 16°C).
2 hours minimum at 20°F to 40°F (-7°C to 4°C).
4 hours minimum at 0°F to 20°F (-18°C to -7°C). Handle the newly assembled joints carefully during these periods. If gaps (step 11) or loose fits are encountered in the system, double these periods.
Step 13. The system shall not be pressurized until the joints have cured (set) at least as long as recommended by the manufacturer. If manufacturer’s recommendation is not available, the following cure times are required.
2.6.3 Threaded Joints. Joints shall be tightened approximately ½ turn past hand tight, using a strap wrench.
Caution: Handtight refers to number of threads to reach handtight with metal pipe. Pipe can be bottomed in small sizes of PVC by hand pressure alone. Do not overtighten.
2.6.4 Elastomeric Gasketed Joints, Procedure:
Step 1. For field cuts, cut end of pipe square with handsaw and miter box, mechanical saw or a tube cutter designed for plastic.
Step 2. Ream and bevel end of pipe (unless already done by manufacturer).
Step 3. If dirty, remove gasket, clean gasket and groove and replace ring.
Step 4. Mark pipe in a contrasting color to indicate the proper insertion depth as recommended by the manufacturer (unless already done by manufacturer).
Step 5. Apply lubricant recommended by pipe manufacturer to end of pipe. Do not apply lubricant to gasket or the groove unless otherwise specifically recommended by the manufacturer.
Step 6. Insert pipe into fitting until mark on pipe is even with fitting.
Note: This depth of insertion is required to properly allow for thermal expansion and contraction. During joint assembly, the previously installed length of pipe should be held so that the existing joints are not pushed together or pulled apart. DO NOT USE METAL STRAPS, CHAINS (OR THE LIKE) FOR ASSEMBLY.
2.7 Material.
2.7.1 Location. PVC piping shall be installed only outside the foundation of any building or structure or parts thereof. It shall be buried in the ground for its entire length except vertical piping may be extended above grade per Section 2.4.4. It shall not be installed within or under any building or structure or mobile home or commercial coach or parts thereof. The term “building or structure or parts thereof” shall include structures such as porches and steps, whether roofed or not, roofed portecocheres, roofed patios, carports, covered walks, covered driveways and similar structures or appurtenances.

Example for Table 2:
For a pressure of 150 psi (1,033.5 kPa) on a 4 inch (102 mm) tee, Table 2 indicates 1,620 pounds (7,209 N) for 100 psi (689 kPa). Therefore, total thrust for 150 psi (1033.5 kPa) will equal 1½ times 1620 pounds (7,209 N) for a total thrust of 2430 pounds (10,810 N).
To determine the bearing area of thrust blocks, refer to Table 4 for the safe bearing load of the soil and divide the total thrust by this safe bearing load.
SOIL | SAFE BEARING LOAD | |
---|---|---|
lbs./sq. ft. | kPa | |
Mulch, Peat, etc. | 0 | 0 |
Soft Clay | 1,000 | 6,890 |
Sand | 2,000 | 13,780 |
Sand and Gravel | 3,000 | 20,670 |
Sand and Gravel Cement with Clay | 4,000 | 27,360 |
Hard Shale | 10,000 | 68,900 |
Example:Assume a 4,000 pound (17,800 N) total thrust was computed. The soil condition is sand. The required bearing area of the thrust block is 4,000 lbs.
(17,800 N) divided by 2,000 lbs. (13,780 kPa) or 2 square feet (0.19 m2).
2.9 Testing.
2.9.1 Rubber Gasketed Joints. Properly sized thrust blocks, either permanent or temporary, shall be installed at all required points before testing. See Section 2.8.4. When concrete thrust blocks are installed, wait at least 24 hours before pressure testing.
2.9.2 Solvent Cement Joints. The entire system shall be purged before testing to eliminate all solvent cement vapors and air.
CAUTION: Water test only.
2.9.3 Identification. A label shall be fastened to the main electrical meter panel stating, "This structure has a nonmetallic water service".
2.10 Sizing.
2.10.1 Piping shall be sized in accordance with UPC Section 610.0. When UPC Appendix A is applicable, use UPC Chart A-5 (Fairly smooth). Flow velocity shall not exceed 8 fps (2.4 m/s). [UPC 610.0]

2.7.3 Selection. Follow manufacturer's recommendations for type of solvent cement for such conditions as temperature over 100°F (38°C), or humidity over 60%.
2.7.4 Handling (to maintain effectiveness). Solvent cement and primer containers no larger than I quart (1 liter) should be used in the field (to avoid thickening due to evaporation). Keep containers closed and in the shade when not in use. Keep applicator submerged in solvent cement between applications. When solvent cement becomes thicker, THROW IT AWAY. Solvent cement shall NOT be thinned.
2.7.5 Size of Applicator. Applicator should be about one-half the pipe diameter. Do not use small applicator on large pipes. Ordinary pure bristle paint brushes or applicators furnished with product are satisfactory. [UPC 316.1.6]
2.7.6 Primers. A listed primer in compliance with ASTM F 656 shall be used on all PVC DWV joints.
2.7.7 Application. Solvent cement and primer shall be applied deliberately, but without delay (two men may be needed to make large joints). Use special care when temperature is over 100°F (38°C) or humidity is over 60%.
2.7.8 SAFETY REQUIREMENTS AND PRECAUTIONS.
2.7.8.1 General. Solvents contained in PVC plastic pipe cements are classified as airborne contaminants and flammable and combustible liquids. Precautions listed in this appendix should be followed to avoid injury to personnel and the hazard of fire.
2.7.8.2 Safety Precautions. Prolonged breathing of solvent vapors should be avoided. When pipe and fittings are being joined in partially enclosed areas, a ventilating device should be used in such a manner to minimize the entry of vapors into the breathing areas.
2.7.8.3 Solvent cements should be kept away from all sources of ignition, heat, sparks and open flame.
2.7.8.4 Containers for solvent cements should be kept tightly closed except when the cement is being used.
2.7.8.5 All rags and other materials used for mopping up spills should be kept in a safety waste receptacle which should be emptied daily.
2.7.8.6 Most of the solvents used in PVC pipe cements can be considered eye irritants and contact with the eye should be avoided for it may cause eye injury. Proper eye protection and the use of chemical goggles or face shields is advisable where the
possibility of splashing exists in handling solvent cements. In case of eye contact, flush with plenty of water for 15 minutes and call a physician immediately.
2.7.8.7 Repeated contact with the skin should be avoided. Proper gloves impervious to and unaffected by the solvents should be worn when frequent contact with the skin is likely. Application of the solvents or solvent cements with rags and bare hand is not recommended. Brushes and other suitable applicators can be used effectively for applying the solvent cement, thus avoiding skin contact. In the event of excessive contact, remove contaminated clothing and wash skin with soap and water.
Step 1 Cut pipe square with hand saw and miter box, mechanical cut-off saw or tube cutter designed for plastic.
Step 2 Ream inside and chamfer outside of pipe (to eliminate all burrs).
Step 3 Clean all dirt, moisture, and grease from pipe and socket. Use a clean, dry rag.
Step 4 Check dry fit of pipe in fitting. Pipe should enter fitting socket from 1/3 to ¾ depth of socket.
Step 5 Soften inside socket surface by applying an aggressive primer.
Step 6 Soften mating outside surface of pipe to depth of socket by applying a liberal coat of the (aggressive) primer. Be sure the entire surface is softened.
Step 7 Again coat inside socket surface with the (aggressive) primer. Then, without delay, apply solvent cement liberally to outside of pipe. Use more than enough to fill any gaps.
Step 8 Apply a light coat of PVC solvent cement to inside of socket using straight outward strokes (to keep excess solvent out of socket). This is also to prevent solvent cement damage to pipe. For loose fits, apply a second coat of solvent cement. Time is important at this stage. See Section 2.7.6.
Step 9 While both the inside socket surface and the outside surface of the pipe are SOFT and WET with solvent cement, forcefully bottom the pipe in the socket, giving the pipe a one-quarter turn, if possible. The pipe must go to the bottom of the socket.
Step 10 Hold the joint together until tight. (Partial set).
Step 11 Wipe excess cement from the pipe. A properly made joint will normally show a bead around its entire perimeter. Any gaps may indicate insufficient cement or the use of light bodied cement on larger diameters where heavy bodied cement should have been used.
Step 12 The system shall not be tested until the joints have cured (set) at least as long as recommended by the manufacturer.

2.4 Trenching, Excavation, and Backfill.
2.4.1 Trenching.
The width of the trench at any point below the top of the pipe should not be greater than necessary to provide adequate room for joining the pipe and compacting the side fills. [UPC 315.0]
2.5 Alignment and Grade.
The pipe should be bedded true to line and grade, uniformly and continuously supported on firm, stable material. Blocking shall not be used to bring the pipe to grade. The bedding shall conform to Section 718.0 of the Uniform Plumbing Code.
2.6 Backfill.
The backfill shall conform to Section 315.4 of the Uniform Plumbing Code.
2.7 Joints.
2.7.1 Caulked Joints.
Make connections or transitions to bell-and-spigot cast iron soil pipe and fittings, and to bell-and-spigot pipe and fittings of other materials with approved mechanical compression joints designed for this use, or caulked joints made in an approved manner. In caulking, pack the joint with oakum or hemp and fill with molten lead to a depth of not less than one (1) inch (25.4 mm). Allow a period of four (4) minutes for cooling, following which, caulk the lead at the inside and outside edges of the joint. Lead shall not be overheated. [UPC 705.1.1]
Note: Caulked joints should be avoided if possible.
2.7.2 Gasket-Type Joints.
Pipe shall be cut square with saws or pipe cutters designed specifically for plastic pipe; protect pipe and fittings from serrated holding devices and abrasion. [UPC 705.1.7]
2.7.3 Solvent Cement Joints.
2.7.3.1 Selection. Solvent cement shall be recommended for ABS by the manufacturer. Follow manufacturer's recommendations for types of solvent cement for such conditions as temperature over 100°F (38°C), or humidity over 60%.
2.7.3.2 Handling (to maintain effectiveness). Solvent cement containers no larger than 1 quart (1 liter) should be used in the field (to avoid thickening due to evaporation). Keep container closed and in the shade when not in use. Keep applicator submerged in solvent cement between applications. When solvent cement becomes thicker, THROW IT AWAY. Solvent cement shall NOT be thinned.
2.7.3.3 Size of Applicator. Applicator should be about one half the pipe diameter. Do not use small applicator on large pipes. Ordinary pure bristle paint brush or applicators furnished with product are satisfactory.
2.7.3.4 Application. Solvent cement shall be applied deliberately, but without delay (two men may be needed to make large joints). Use special care when temperature is over 100°F (38°C) or humidity is over 60%.
2.7.4 SAFETY REQUIREMENTS AND PRECAUTIONS.
2.7.4.1 General. Solvents contained in ABS plastic pipe cements are classified as airborne contaminants and flammable and combustible liquids. Precautions listed in this appendix should be followed to avoid injury to personnel and the hazard of fire.
2.7.4.2 Safety Precautions. Prolonged breathing of solvent vapors should be avoided. When pipe and fittings are being joined in partially enclosed areas, a ventilating device should be used in such a manner to minimize the entry of vapors into the breathing areas.
2.7.4.3 Solvent cements should be kept away from all sources of ignition, heat, sparks, and open flame.
2.7.4.4 Containers for solvent cements should be kept tightly closed except when the cement is being used.
2.7.4.5 All rags and other materials used for mopping up spills should be kept in a safety waste receptacle which should be emptied daily.
2.7.4.6 Most of the solvents used in ABS pipe cements can be considered eye irritants and contact with the eye should be avoided for it may cause eye injury. Proper eye protection and the use of chemical goggles or face shields is advisable where the possibility of splashing exists in handling solvent cements. In case of eye contact, flush with plenty of water for 15 minutes and call a physician immediately.
2.7.4.7 Repeated contact with the skin should be avoided. Proper gloves impervious to and unaffected by the solvents should be worn when frequent contact with the skin is likely. Application of the solvents or solvent cements with rags and bare hand is not recommended. Brushes and other suitable applicators can be used effectively for applying the solvent cement, thus avoiding skin contact. In the event of excessive contact, remove contaminated clothing and wash skin with soap and water.
Step 1 Cut pipe square with hand saw and miter box, mechanical cut-off saw, or tube cutter designed for plastic.
Step 2 Ream inside and chamfer outside of pipe (to eliminate all burrs).
Step 3 Clean all dirt, moisture, and grease from pipe and socket. Use a clean, dry rag.
Step 4 Check dry fit of pipe in fitting. Pipe should enter fitting socket from 1/3 to ¾ depth of socket.
Step 5 Apply a light coat of ABS solvent cement to inside of socket using straight
outward strokes (to keep excess solvent out of socket). This is also to prevent solvent cement damage to pipe. For loose fits, apply a second coat of solvent cement. Time is important at this stage. See Section 2.7.3.4.
Step 6 While both the inside socket surface and the outside surface of the pipe are SOFT and WET with solvent cement, forcefully bottom the pipe in the socket, giving the pipe a one-quarter turn, if possible. The pipe must go to the bottom of the socket.
Step 7 Hold the joint together until tight (partial set).
Step 8 Wipe excess cement from the pipe. A properly made joint will normally show a bead around its entire perimeter. Any gaps may indicate insufficient cement or the use of light bodied cement on larger diameters where heavy bodied cement should have been used.
Step 9 The system shall not be tested until the joints have cured (set) at least as long as recommended by the manufacturer.
2.7.5 Special Joints.
2.7.5.1 Connection to Non-Plastic Pipe.
When connecting plastic pipe to other types piping, use only approved types of fittings and adapters, designed for the specific transition intended.

Class 200 | 4 – 24 inch incl. (102 – 610 mm incl.) | 200 psi (1,378 kPa) |
2.5.3 Laterals and Saddles. Installation of laterals, saddles, or tapped couplings in AC piping shall be as required by their listings.
2.5.4 Thrust Blocking. Thrust blocks shall be installed at:
The size and type of thrust block shall be based on the pressure rating of the pipe (or line test pressure, if greater than piping rating), pipe size and kind of soil 2.5.4(b). Refer to Table 1 for thrust at fittings for a pressure of one hundred (100) pounds per square inch (689 kPa).
2.5.5 To determine the bearing area of thrust blocks, refer to Table 2 for the safe bearing load of the soil and divide the total thrust by this safe bearing load.
2.5.6 Thrust blocks shall be located as shown on Chart 1.
2.5.7 Testing
2.5.7.1 The portion of the line being tested should be complete with thrust blocks or properly sized temporary thrust blocking. The line may be pressure tested immediately after installation, provided however, that if poured concrete thrust blocks have been utilized, they have had a 24-hour period to attain an initial cure. [UPC 609.4]
2.5.7.2 The entire system shall be filled with water, purged of air, and tested at a pressure at least equal to the eventual operating pressure for at least one (1) hour before inspection and backfilling of trench. It is recommended that the test pressure not exceed the working pressure of the pipe.
CAUTION: AIR TESTING IS PROHIBITED.
2.5.7.3 Identification. A label shall be fastened to the main electrical meter panel stating, "This structure has a non-metallic water service."
2.6 Sizing. Piping shall be sized in accordance with UPC Section 610.0. When UPC Appendix A is applicable, Chart A-5 (Fairly Smooth Pipe) may be used. Flow velocities shall be limited to a maximum of 8 fps (2.4 m/s). When using UPC, Table 6-5, required by UPC Section 610.0, velocities shall also be checked and limited using UPC Chart A-5.

1.2 Special Requirements for CPVC Installation within Residential Structures. [HCD 1]
In addition to the other requirements in the California Plumbing Code and this Appendix for the installation of CPVC Solvent Cemented Hot and Cold Water Distributions Systems, all installations of CPVC pipe within residential structures shall meet the following:
1.2.1 Flushing Procedures. All installations of CPVC pipe within residential structures shall be flushed twice over a period of at least one (1) week. The pipe system shall be first flushed for at least 10 minutes and then filled and allowed to stand for no less than 1 week, after which all the branches of the pipe system must be flushed long enough to fully empty the contained volume. At the time of fill, each fixture shall have a removable tag applied stating:
“This new plumbing system was first filled on (date) by (name). The California Department of Housing and Community Development requires that the system be flushed after standing at least one week after the fill date specified above. If the system is used earlier than one week after the fill date, the water must be allowed to run for at least two minutes prior to use for human consumption. This tag may not be removed prior to flushing, except by the homeowner.”
1.2.2 Worker Safety Measures. Mechanical ventilation sufficient to maintain exposures below the relevant exposure limits established by state regulation shall be provided in enclosed spaces. This ventilation shall be directed at the breathing zone of the worker installing the pipe. Where mechanical ventilation is not practical, respirators, suitable for organic vapors, shall be used. For the purpose of this subdivision, an enclosed space is defined as:
Installers of CPVC pipe withing residential structures shall use non-latex thin gauge (4 millimeters) nitrile gloves, or other gloves providing an equivalent or better degree of protection during the installation of the CPVC plumbing system. Gloves shall be provided to all workers by the contractor, or plumbing subcontractor, and shall be replaced upon contamination by cements.

2.7.2 Selection. Follow the manufacturer's recommendations for type of solvent cements for such conditions as temperatures over 100°F (38°C), or humidity over 60%.
2.7.3 Handling (to maintain effectiveness). Package solvent cement in containers no larger than 1 quart (1 liter). Keep solvent cement can closed and in the shade when not in use. Keep applicator submerged in solvent cement between applications. Discard solvent cement when it thickens appreciably or gels. Solvent cement shall not be thinned.
2.7.4 Primer. A listed primer in compliance with ASTM F 656 shall be used with CPVC solvent cements that require the use of a primer. CPVC solvent cements that do not require the use of a primer are permitted for joints up to 2 inches in size.
2.7.5 Size of Applicator. Applicator should be about one half of the pipe diameter. Do not use small applicator on large pipes.
2.7.6 Procedures
Step 1. Cut pipe square with hand saw and mitre box, mechanical cutoff saw or tube cutter designed for plastic.
Step 2. Ream and chamfer pipe (to eliminate sharp edges, beads and all burrs).
Step 3. Clean all dirt, moisture and grease from pipe and fitting socket. Use a clean, dry rag.
Step 4. Check dry fit of pipe in fittings. Pipe should enter fitting socket ¼ to ¾ of socket depth. On larger sizes of Sch. 80 fittings, a looser fit may be expected. This is a normal condition, and requires care to apply an adequate amount of cement.
Step 5. Apply CPVC primer, if required (See Section 2.7.4) to inside of fitting socket. Take care to avoid puddling.
Step 6. Apply CPVC primer, if required to outside surface of pipe to depth of fitting socket.
Step 7. When using solvent cements requiring a primer wait until primer surface is tacky. DO NOT attempt to soften (dissolve) the surface as is required for PVC.v
Step 8. Apply a liberal coat of CPVC solvent cement to the outside surface of the pipe to the depth of the fitting socket.
Step 9. Apply a light coat of CPVC solvent cement to inside of fitting socket. Apply a second liberal coat of cement to the pipe end. Take particular care in cementing larger sizes of Sch. 80 fittings. Be sure all surfaces are coated.
Step 10. While both the inside socket surface and the outside surface of the pipe are WET with solvent cement, forcefully

bottom the pipe in the socket, giving the pipe a quarter turn while inserting, if possible.
Step 11. Hold the joint together for 10 to 15 seconds to assure that the pipe remains bottomed against the pipe stop.
Step 12. Do not disturb the joint for at least 30 minutes.
Note: The joint is weak until the cement is dry. If the joint is adjusted after it is set, the joint will be ruined. See Table 2 for recommended set time.

2.0 PRODUCT REQUIREMENTS.
2.1 Minimum Standards.
2.1.1 Materials. Materials shall comply with the appropriate standard in Table 14-1 of the UPC.
Note:The nominal or standard size of copper and copper alloy welded water tube is always 0.125 inch (3.8 mm) or 1/8 inch (3.8 mm) smaller than the actual outside diameter dimension of the tube. For example, 3 inch (76 mm) nominal size copper plumbing, tube measures 31/8 inch (79.2 mm) O.D., ½ inch (12.7 mm) nominal size copper plumbing tube measures 5/8 inch (15.9 mm) O.D., etc.
2.2 Use of Copper Tubing.
2.2.1 Markings. Markings shall be visible for inspection.
2.2.1.1 Water tube shall bear the following incised marked at not over 18 inch (457 mm) intervals:
2.2.1.2 All hard drawn tube shall be identified through out its entire length by a colored marking not less than 3/16 inch in height, including legend repeated at intervals not greater than 3 feet (914 mm). The legend shall include the type of tube, welded, ASTM specification, name or trademark of the manufacturer of both, and the country of origin. [UPC 604.3]
2.3 Joints.
2.3.1 General Information. Copper tube and fittings maybe joined in a number of ways, depending on the purpose of the system. Soldering and brazing with capillary fittings are the methods used most.
The American Welding Society defines soldering as a joining process which takes place below 840°F (449°C) and brazing as a similar process which occurs above 840°F (449°C) but below the melting point of the base metals. In actual practice for copper systems, most soldering is done at temperatures ranging from about 350°F to 550°F (177°to 288°C), while most brazing is done at temperatures ranging from 1100° F to 1500°F (593°C to 816°C). The choice between soldering or brazing will generally depend on operating conditions. Solder joints are generally used where the service temperature does not exceed 205°F (96°C), while brazed joints can be used where greater strength is required, or where system temperatures are as high as 400°F (204°C). [UPC 316.1]
2.3.2 Fittings for Soldered, Brazed, and Flared Joints.Fittings are available in all standard tube sizes and in a wide variety of types to cover needs for plumbing. They can be either soldered or brazed, although brazing cast fittings requires care. Wrought copper pressure fittings are also available over a wide range of sizes and types. These, too, can be joined by either soldering or brazing, and wrought fittings are preferred where brazing is the joining method. Otherwise, the choice between cast and wrought fittings is largely a matter of the user's preference. Flared-tube fittings provide metal-to-metal contact similar to ground joint unions; both can be easily taken apart and reassembled. They are especially useful where residual water cannot be removed from the tube and soldering is difficult. Flared joints may be required where a fire hazard exists and the use of a torch to make soldered or brazed joints is not allowed.
2.3.3 Solders.
Note: Users of the Uniform Plumbing Codes are reminded that provisions of the Federal Clean Drinking Act of 1986, which all must obey, forbid the use of solder which contains in excess of 0.2% of lead, by weight in potable water systems. The provisions of the act are incorporated in all ordinances, statutes, state and municipal regulations by reference and by operation of law.
The selection of a solder depends on the operating pressure and temperature of the line. Consideration should also be given to the stresses on the joint caused by thermal expansion and contraction. However, stresses due to temperature changes should not be significant in two commonly encountered cases: When tube lengths are short, or when expansion loops are used in long tube runs.
Solder is generally used in wire form, but paste-type solders are also available. These are finely granulated solders in suspension in a paste flux, When using paste-type solders, observe these four rules:
Solders are available containing small amounts of silver or other additives to impart special properties. Such solders may require special fluxes. The manufacturer's recommendations should be consulted regarding proper procedures and fluxes for such solders and about the expected properties.
2.3.4 Soldering Flux.
The functions of the soldering flux are to remove residual traces of oxides, to promote wetting, and to protect the surfaces to be soldered from oxidation during heating. The flux should be applied to clean surfaces and only enough should be used to lightly coat the areas to be joined.
An oxide film may reform quickly on copper after it has been cleaned. Therefore, the flux should be applied as soon as possible after cleaning.
CAUTION
Careless workmanship, especially during flux applications, can result in corrosion of the tube long after the system has been installed. If excessive flux is used, the residue inside the tube can cause corrosion. In an extreme case, such residual flux can actually lead to perforation through the tube wall causing leakage. To guard against this danger, it is important (1) to choose a flux that is not too corrosive, and (2) to use only the minimum amount actually needed to make the joint.
2.3.5 Solder Joints.
Soldering and brazing both involve basic steps, which must be executed with care and craftsmanship. The steps are:
Each step contributes to a strong, dependable joint.
2.3.5.1 Measuring.
Measuring the length of each tube segment must be accurate. Inaccuracy can compromise joint quality. If the tube it too short it will not reach all the way into the socket of the fitting and a proper joint cannot be made. If the tube segment is too long, there is danger of cocking the tube in the fitting and putting strain on the system which could affect service life.
2.3.5.2 Cutting.
Once the tube is measured it can be cut. Cutting can be accomplished in a number of different ways to produce a satisfactory square end. The tube can be cut with a disc-type tube cutter, a hacksaw, an abrasive wheel, or with a stationary or portable bandsaw. Care must be taken that the tube is not deformed while being cut. Regardless of method, the cut must be square with the run of the tube so that the tube will seat properly in the fitting socket.
2.3.5.3 Reaming.
All pipe and tube shall be reamed to the full I.D. of the pipe and tube.
Tools and used to ream tube ends include the reaming blade on the tube cutter, half-round or round files, a pocket knife, and a suitable deburring tool. With annealed tube, care must be taken not to deform the tube end by applying too much pressure. Both the inside and the outside of the tube may require removal of the burr.
2.3.5.4 Cleaning.
The removal of oxides and surface soil is crucial if filler metal is to flow properly into the joint. Unremoved oxide, surface soil, and oil can interfere with the strength of the joint and cause failure.
Mechanical cleaning is a simple operation. The end of the tube should be abraded lightly using sand cloth or nylon abrasive pads for a distance only slightly more than the depth of the fitting socket. The socket of the fitting should also be cleaned using sand cloth, abrasive pads, or a properly sized fitting brush.
Copper is a relatively soft metal. If too much material is removed, a loose fit will result and interfere with satisfactory capillary action in making the joint. The capillary space between the tube and fitting is approximately 0.004 inch (0.1 mm). Solder or brazing filler metal can fill this gap by capillary action. This spacing is critical for the filler metal to flow into the gap and form a strong joint.
Surfaces, once cleaned, should not be touched with bare hands or oily gloves. Skin oils, lubricating oils, and grease impair solder flow and wetting.
2.3.5.5 Fluxing.
Stir the flux before use. A good flux will dissolve and remove traces of oxide from the cleaned surfaces to be joined, protect the cleaned surfaces from reoxidation during heating and promote wetting of the surfaces by the solder. A thin, even coating of flux should be applied with a brush to both tube and fitting. Do not apply with fingers. Chemicals in the flux can be harmful if carried to the eyes or open cuts.
2.3.5.6 Assembly and Support.
After both tube and fitting surfaces are properly fluxed, they should be assembled, making sure the tube seats against the base of the fitting socket. A slight twisting motion ensures even distribution by the flux. Remove excess flux. Care must be taken to assure that the tube and fittings are properly supported with a uniform capillary space around the entire circumference of the joint. Uniformity of capillary space will ensure good filler metal penetration if the guideliness of successful joint making are followed. Excessive joint clearance can cause the filler metal to creck under stress or vibration.
The joint is now ready for soldering. Joints prepared and ready for soldering should be completed the same day and not left unfinished overnight.
2.3.5.7 Heating.
Because an open flame may be used for soldering, and because flammable gases are used, safety precautions must be observed. The heat is generally applied using an air/fuel touch. Such torches use acetylene or an LP gas. Electric resistance tools can also be used.
Heating should begin with the flame perpendicular to the tube. The copper tube conducts the initial heat into the fitting socket for even distribution of heat inside and out. The extent of this preheating depends upon the size of the joint. Experience will indicate the amount of time needed. The flame should now be moved into the fitting. Then move the flame from the fitting socket back onto the tube a distance equal to the depth of the fitting socket. Touch the solder to the joint. If the solder does not melt, remove it and continue the heating process. Be careful not the overheat or to direct the flame into the fitting cup. This could cause the flux to burn and destroy its effectiveness. When the melting temperature of the sodler has been reached, heat may be applied to the base of the cup to aid capillary action in drawing the solder into the cup.
2.3.5.8 Applying the Filler Metal.
For tube in a horizontal position, start applying the solder slightly off-center at the bottom of the joint. Proceed across the bottom of the fitting and up to the top center position. Return to the point of
beginning, overlap the starting point, and then proceed up the incompleted side to the top, again, overlapping the solder.
For joints in the vertical position, a similar sequence of overlapping passes should be made, starting wherever is convenient. Molten solder will be drawn into the joint by capillary action regardless of whether the solder is being fed upward, downward, or horizontally.
2.3.5.9 Cooling and Cleaning.
After the joint has been completed, natural cooling is best. Shock cooling with water may cause unnecessary stress on the joint and result in eventual failure. When cool, clean off any remaining flux with a wet rag.
2.3.6 Brazed Joints.
Brazing is the second most commonly used method for joining copper tube. Making brazed joints is similar to making soldered joints with respect to measuring, cutting, reaming, cleaning, assembly and support. And as in soldering, the brazing filler metal is melted by the heat of the tube and fitting and drawn into the joint by capillary action. [UPC 316.1.7]
The major differences between soldering and brazing are the:
2.3.6.1 Brazing Flux.
The fluxes used for brazing copper joints are different in composition from soldering fluxes. The two types cannot be used interchangeably. Brazing fluxes are water based, whereas most soldering fluxes are petroleum based. Similar to soldering fluxes, brazing fluxes dissolve and remove residual oxide from the metal surface, protect the metal from reoxidation during heating and promote wetting of the surfaces to be joined by the brazing filler metal.
Fluxes also provide the draftsman with an indication of temperature. Application of the flux is the same as when soldering. If the outside of the fitting and the heat-affected area of the tube are covered with flux (in addition to the end of the tube and the cup), oxidation will be prevented and the appearance of the joint will be greatly improved.
2.3.6.2 Brazing Filler Metals.
There are two general types of brazing filler metal used for joining copper tube. Classified according to their components, they are: BCuP (Brazing-Copper-Phosphorous) and BAg (Brazing-Silver).
BCuP filler metals are preferred for joining copper tube and fittings. The phosphorous in them acts as a fluxing agent and the lower percentage of silver makes them relatively low cost. When using copper tube, wrought copper fittings, and BCuP brazing filler metal, fluxing is optional. However, when cast fittings are brazed, flux must be used.
2.3.6.3 Heating.
Oxy/fuel torches are generally used for brazing because of the higher temperatures required.
Recent innovations in tip design make air/fuel torches useful on a wider range of sizes for brazing.
When working at brazing temperatures, safety precautions must be followed and care taken to protect both the operator and the materials being used.
The heating operation is the same as for soldering. First preheat the tube and then the tube and fitting. When the filler metal starts to melt, apply heat at the base of the fitting socket to help draw the brazing filler metal in by capillary action.
2.3.6.4 Applying Brazing Filler Metal.
Remember to allow the heat of the joint, not the flame, to melt the filler metal. The melted filler metal will be drawn into the joint by capillary action. It is very important that the flame be in continuous motion. It must not be allowed to remain on any one point long enough to burn through the tube or fitting.
If the filler metal fails to flow, or has the tendency to ball-up, it indicates either that there is oxide on the surfaces being joined or that the parts to be joined are not hot enough. If the filler metal refuses to enter the joint, the fitting cup is not hot enough. If it tends to flow over the outside of either part of the joint it indicates that part is over-heated. When the joint is completed, a continuous fillet should be visible completely around the joint.
Large diameter tube is more difficult to heat to the desired temperature. The use of a heating tip or rosebud may be necessary to maintain the proper temperature over the area being brazed. Once total heat control is attained, follow the same procedures used for smaller tube.
2.3.6.5 Cooling and Cleaning.
When the brazed joint is finished, allow it to cool naturally. Flux residues and some oxides formed by heating can be removed by washing with hot water and brushing with a stainless steel wire brush.
2.3.7 Flared Joints.
2.3.7.1 Flared Joints with Impact Flaring Tools:
Step 1 Cut the tube to the required length.
Step 2 Remove all burrs. This is very important to assure metal-to-metal contact.
Step 3 Slip the coupling nut over the end of the tube.
Step 4 Insert flaring tool into the tube end.
Step 5 Drive the flaring tool by hammer strokes, expanding the end of the tube to the desired flare. This requires a few moderately light strokes.
Step 6 Assemble the joint by placing the fitting squarely against the flare. Engage the coupling nut with the fitting threads. Tighten with two wrenches, one on the nut and one on the fitting [UPC 606.1.1]
2.3.7.2 Flared Joints with Screw-Type Flaring Tools:
Steps 1-3 Same as for impact flaring previously described.
Step 4 Clamp the tube in the flaring block so that the end of the tube is slightly above the face of the block.
Step 5 Place the yoke of the flaring tool on the block so that the beveled end of the compressor cone is over the tube end.
Step 6 Turn the compressor screw down firmly, forming the flare between the chamber in the flaring block and the beveled compressor cone.
Step 7 Remove the flaring tool. The joint can now be assembled as in Step 6 for impact flaring. [UPC 606.2.1]

Note: There are various hydraulic formulas for the flow of water in pipe. With high velocity and attendant turbulent flow, there can be excessive noise and piping wear.
The designer should aim for maximum flow velocities in the range of 5 to 8 feet per second (1.5—2.4 meters per second) to minimize noise and erosion problems. For the smallest tube sizes, the designer is wise to work at the bottom of this range, as a maximum, to guard against local high velocities building up due to faulty workmanship (e.g. burrs at tube ends which are not properly reamed) or unusually numerous changes in flow direction.
3.0 GENERAL INFORMATION.
3.1 It is not possible to cover all the variables of a plumbing system; however, the following information may prove helpful:
3.2 Expansion Loops – Copper tube, like all piping materials, expands and contracts with temperature changes. Therefore, in a copper tube system subjected to excessive temperature changes, the line tends to buckle or bend when it expands unless compensation is build into the system. Severe stresses on the joints may also occur. Such stresses, buckles, or bends are prevented by the use of expansion joints or by installing offsets, “U” bends, coil loops, or similar arrangements in the tube assembly. These specially shaped tube segments take up expansion and contraction without excessive stress. The expansion of a length of copper tube may be calculated from the formula:
Temperature Rise (°F) x length (feet) x 12 (inches per foot) x
Expansion Coefficient (inch per inch per °F) = Expansion (inches), or
Temperature Rise (°C) x Length (meter) x 1000 (mm per meter) x Expansion Coefficient (mm per mm per °C) = Expansion (mm).
Calculations for expansion and contraction should be based on the average coefficient of expansion of copper which is 0.0000094 per degree F (1.692 x 10-5 per degree C), between 70°F and 212° F (21° C and 100°C). For example, the expansion of each 100 feet (30.5 meters) of length of any size tube heated from room temperature (70°F) to 170°F (a 100°F (55.6°C) rise) is 1.128 inches (28.7 mm).
100°F x 100 feet x 12 inch/foot x 0.0000094 inch/inch/°F = 1.128 inch, or 55.6°C x 30.48 mm x 1000 mm/m x 1.692 x 10-5 mm/mm/°C = 28.7 mm
3.3 Tube Supports – See Section 314.0 and Table 3-2 of the Uniform Plumbing Code.
3.4 Bending– Copper tube, properly bent, will not collapse on the outside of the bend and will not buckle on the inside of the bend. Tests demonstrate that the bursting strength of a bent copper tube can be greater than it was before bending. Because copper is readily formed, expansion loops and other bends necessary in an assembly are quickly and simply made if the proper method and equipment are used. Simple hand tools employing mandrels, dies, forms, and fillers, or power-operated bending machines, are used.
3.4.1 Both annealed tube and bending-temper tube can be bent with hand benders. The proper size bender for each size tube must be used. Usually the size of the tool corresponds to the nominal outside diameter of the tube, not the standard tube size. For a guide to the typical bend readii, see the following bending guide for copper tube.

(30.5 m), to compensate for thermal expansion and contration before stabilizing hose. Stabilize hose by bringing it approximately to operating temperature before testing and backfilling by one of the following methods:
3.3 Exposed Hose. Hose above grade when located on the exterior of the building or structure shall be protected from mechanical damage to the satisfaction of the Administrative Authority. Where exposed to sunlight, the hose shall be wrapped with at least 0.040 in. (1.0 mm) of tape or other approved method acceptable to the Administrative Authority.
4.0 TRENCHING, COVER, AND BACKFILL.
4.1 Trenching and Cover. Trench bottoms shall be uniformly graded and shall be of either undisturbed soil or shall consist of a layer or layers of compacted backfill so that minimum settlement will take place.
4.2 Backfill. Selected backfill shall be used to provide firm continuous support and proper compaction. Backfill over hose, except that joints shall be left exposed. After inspection and pressure test, complete backfill to a minimum of 12 in. (0.3 m) cover.
5.0 INSTALLATION.
5.1 Solvent Cement Joints.
5.1.1 Selection. Solvent cement shall be recommended for flexible PVC hose by the manufacturer. Follow manufacturer's recommendations for types of solvent cement for flexible PVC hose.
5.1.2 Handling (to maintain effectiveness). Use solvent cement in containers no larger than 1 quart (1 liter). Keep solvent cement can closed and in the shade when not in use. Keep applicator submerged in solvent cement between application. When solvent cement becomes thicker, THROW IT AWAY. Solvent cement shall NOT be thinned.
5.1.3 Size of Applicator. Follow manufacturer's recommendations.
5.1.4 Application. Follow manufacturer's recommendations.
5.1.5 General Principles.
5.1.5.1 To consistently make good joints, the following should be clearly understood and adhered to:
5.1.5.2 Penetration and dissolving can be achieved by the cement itself, by a suitable primer, or by the use of both primer and cement. A suitable primer will penetrate and dissolve the plastic more quickly than cement alone. In cold weather more time and additional applications are required (see Figure 1).
FIGURE 1
AREAS OF HOSE AND FITTINGS TO BE SOFTENED (DISSOLVED) AND PENETRATED
5.1.5.3 More than sufficient cement to fill the loose part of the joint must be applied (see Figure 2). Besides filling the gap, adequate cement layers will penetrate the surfaces and also remain wet until the joint is assembled.
FIGURE 2
CEMENT COATINGS OF SUFFICIENT THICKNESS
5.1.5.4 If the cement coatings on the hose and fittings are wet and fluid when assembly takes place, they will tend to flow together and become one cement layer. Also, if the cement is wet the surfaces beneath them will still be soft, and these dissolved surfaces in the tight part of the joint will tend to fuse together (see Figure 3).
FIGURE 3
ASSEMBLY OF SURFACES WHILE THEY ARE WET AND SOFT
5.1.5.5 As the solvent dissipates, the cement layer and the dissolved surfaces will harden with a corresponding increase in joint strength. A good joint will take the required working pressure long before the joint is fully dry and final strength is obtained. In the tight (fused) part of the joint, strength will develop more quickly than in the looser (bonded) part of the joint. Completed joints should not be disturbed until they have cured sufficiently to withstand handling. Joint strength develops as the cement dries. Information about development of bond strength of solvent cemented joints is available (see Figure 4).
FIGURE 4 BONDED AND FUSED SURFACES OF JOINED HOSES
5.1.6 Procedure.
Note: Do not take SHORT CUTS. Most failures are caused by short cuts. DON'T TAKE A CHANCE.
Step 1 Cut hose square with hand saw and miter box, mechanical cut-off saw, or tube cutter designed for plastic.
Step 2 Ream and chamfer hose (to eliminate sharp edges, beads and all burrs).
Step 3 Clean all dirt, moisture, and grease from hose and fitting socket. Use a clean, dry rag.
Step 4 Check dry fit of hose in fitting. Hose should enter fitting socket from & to ¾ depth of socket.
Step 5 Soften inside socket surface by applying an aggressive primer which is a true solvent for PVC and is recommended by the manufacturer.
Step 6 Soften mating outside surface of hose to depth of socket by applying a liberal coat of the (aggressive) primer. Be sure entire surface is softened.
Step 7 Again coat inside socket surface with the (aggressive) primer. Then, without delay, apply solvent cement liberally to outside of hose. Use more than enough to fill any gaps.
Step 8 Apply a light coat of PVC solvent cement to inside of socket using straight outward strokes (to keep excess solvent out of socket). This is also to prevent solvent cement damage to hose. For loose fits, apply a second coat of solvent cement. Time is important at this stage. (See 5.1.4)
Step 9 While both the inside socket surface and the outside surface of the hose are SOFT and WET with solvent cement, forcefully bottom the hose in the socket, giving the hose a one-quarter turn, if possible. The hose must go to the bottom of the socket.
Step 10 Hold the joint together until tight.
Step 11 Wipe excess cement from the hose. A properly made joint will normally show a bead around its entire perimeter. Any gaps may indicate insufficient cement or the use of light bodied cement on larger diameters where heavy bodied cement should have been used.
Step 12 Do not disturb joint for the following periods:
30 minutes minimum at 60°F to 100°F (16°C to 38°C)
1CAUTION: Primers are toxic. Don't allow them to touch skin. Suitable gloves are advised.
1 hour minimum at 40°F to 60°F (4°C to 16°C)
2 hours minimum at 20°F to 40°F (-7°C to 4°C)
4 hours minimum at 0°F to 20°F (-18°C to -7°C)
Handle the newly assembled joints carefully during these periods. If gaps (step 11) or loose fits are encountered in the system, double these periods.
Step 13 The system shall not be pressurized until the joints have cured (set) at least as long as recommended by the manufacturer. If manufacturer's recommendation is not available, the cure times as shown in Table 1 are required.
5.1.7 Installation and Testing.
5.1.7.1 Installation. The hose shall be properly supported to prevent excessive sagging.
5.1.7.2 Testing.
Exception: All exposed equipment need not be tested as required in this section.
5.1.8 SAFETY REQUIREMENTS AND PRECAUTIONS1
5.1.8.1 General. Solvents contained in PVC plastic hose cements are classified as airborne contaminants and flammable and combustible liquids. Precautions listed in this section should be followed to avoid injury to personnel and the hazard of fire.
5.1.8.2 SAFETY PRECAUTIONS
SIZES ½″ to 1¼″ 12.7 mm to 31.8 mm | SIZES 1½″ to 3″ 38.1 mm to 76.2 mm | SIZES 3½″ to 8″ 88.9 mm to 203.2 mm | ||||

A. It is important to note that at temperatures colder than 20°F (-6.7°C) on sizes that exceed 3 in. (76.2 mm), test results indicate that many variables exist in the actual cure rate of the joint. The data expressed in these categories represent only estimated averages. In some cases, cure will be achieved in less time, but isolated test results indicate that even longer periods of cure may be required. | ||||||
B. These cure schedules are based on laboratory test data obtained on Net Fit Joints (NET FIT = in a dry fit the pipe bottoms snugly in the fitting socket without meeting interference). The relative humidity in these tests was 50% or less. Higher relative humidity may require longer cure periods. | ||||||

For the users of this code, we are including a short explanation and some conversion tables to aid in the conversion of our familiar English units to the forthcoming SI units.
This is written with the code users in mind, and will detail only those measurements used in everyday work and calculations. For the scientific units, we recommend the use of ANSI Z210.1, "Metric Practice Guide.".
Our present system of measuring involves the three dimensions of force, length and time. The SI units involve mass, length, and time. The change of force to mass has meaning in scientific and engineering work, but for practical use in ordinary construction, we will show kilogram to pounds conversion values, although an exact conversion would be pounds force divided by the acceleration due to gravity to mass units.
In the same manner, the SI units for temperature expressed in Kelvins and based on absolute zero will be given as degrees Celsius, which is the more familiar and practical Centigrade degrees.
The SI system measures angles in radians where there are 2 pi radians in a circle, but using a 1.5708 bend to change from a vertical stack to a horizontal house drain is not as easy as calling out a 1/4 bend or an ell for water piping.
The foregoing notes are intended to show that in making conversions from one unit system to another, a little common sense must be used and the degree of accuracy needed to do the job at hand.
The following tables are set up using this approach and using the preferred SI units.
When the plumbing industry, including plumbers, suppliers, and manufacturers, actually begins the metric conversion program, it will undoubtedly follow the guidelines of committees selected from all phases of the construction industry as set up under the American National Metric Council.
The final preferred units used will be those that apply to our industry and will be of the magnitude to simplify and ease job calculations and avoid confusion and ambiguity.
The conversion looks complex and confusing, but when the metric system was first proposed in France, an attempt was made to include a ten-hour day, a ten-day week, and ten months to the year, but cooler heads prevailed and our time still follows the sun and seasons. Likewise, assigning new units or numbers to the quantities we must work with cannot change the basic hydraulic principles that plumbers have worked with throughout history.
Information on conversion factors is provided by ANSI, the American National Metric Council, and the Division of Designatronics, Inc.
