A REDUCED-SIZE FLEXIBLE WATER CONNECTOR INSTALLED BETWEEN THE SUPPLY PIPE AND THE FIXTURE SHALL <br />BE OF AN APPROVED TYPE. THE SUPPLY PIPE SHALL EXTEND TO THE FLOOR OR WALL ADJACENT TO THE FIXTURE. <br />4.WHERE WATER PRESSURE WITHIN A BUILDING EXCEEDS 80 PSI STATIC, AN APPROVED WATER PRESSURE-REDUCING VALVE <br />CONFORMING TO ASSE 1003 OR CSA B356 WITH STRAINER SHALL BE INSTALLED TO REDUCE THE PRESSURE IN THE WATER <br />DISTRIBUTION PIPING TO NOT GREATER THAN 80 PSI STATIC. <br />4.1.THE PRESSURE-REDUCING VALVE SHALL BE DESIGNED TO REMAIN OPEN TO PERMIT UNINTERRUPTED WATER FLOW IN <br />CASE OF VALVE FAILURE. <br />5.A WATER-HAMMER ARRESTOR SHALL BE INSTALLED WHERE QUICK-CLOSING VALVES AND METALLIC PIPING ARE USED. NOT <br />REQUIRED WHERE PLASTIC PIPE IS USED FOR WATER DISTRIBUTION PIPING. <br />6.PIPE AND PIPE FITTINGS, INCLUDING VALVES AND FAUCETS, UTILIZED IN THE WATER SUPPLY SYSTEM SHALL HAVE NOT MORE <br />THAN 8-PERCENT LEAD CONTENT. <br />6.1.PIPE, PIPE FITTINGS, JOINTS, VALVES, FAUCETS AND FIXTURE FITTINGS UTILIZED TO SUPPLY WATER FOR DRINKING OR <br />COOKING PURPOSES SHALL COMPLY WITH NSF 372 AND SHALL HAVE A WEIGHTED AVERAGE LEAD CONTENT OF 0.25 <br />PERCENT OR LESS. <br />7.THE DEVELOPED LENGTH OF HOT OR TEMPERED WATER PIPING, FROM THE SOURCE OF HOT WATER TO THE FIXTURES THAT <br />REQUIRE HOT OR TEMPERED WATER, SHALL NOT EXCEED 50 FEET. <br />8.THE WATER SUPPLY CONNECTION TO COFFEE MACHINES AND NONCARBONATED BEVERAGE DISPENSERS SHALL BE <br />PROTECTED AGAINST BACKFLOW BY A BACKFLOW PREVENTER CONFORMING TO ASSE 1022 OR BY AN AIR GAP. <br />9.THE SUPPLY LINES AND FITTINGS FOR PLUMBING FIXTURES SHALL BE INSTALLED SO AS TO PREVENT BACKFLOW. PLUMBING <br />FIXTURE FITTINGS SHALL PROVIDE BACKFLOW PROTECTION IN ACCORDANCE WITH ASME A112.18.1/CSA B125.1. <br />SANITARY PIPING <br />3.HORIZONTAL DRAINAGE PIPING SHALL BE INSTALLED IN UNIFORM ALIGNMENT AT UNIFORM SLOPES. ALL BURIED SANITARY <br />SHALL HAVE A MINIMUM SLOPE OF 2% FOR LESS THAN 3" INCH SIZE AND A MINIMUM SLOPE OF 1% FOR 4-6 INCH SIZE. <br />4.THE SIZE OF THE DRAINAGE PIPING SHALL NOT BE REDUCED IN SIZE IN THE DIRECTION OF THE FLOW. <br />5.HORIZONTAL DRAINAGE PIPES IN BUILDINGS SHALL HAVE CLEANOUTS LOCATED AT INTERVALS OF NOT MORE THAN 100 FEET. <br />6.ONE CLEANOUT SHALL BE REQUIRED FOR EVERY FOUR HORIZONTAL 45-DEGREE CHANGES LOCATED IN SERIES. <br />PIPING INSULATION <br />1.WATER PIPING INSULATION MUST SATISFY TABLE 120.3-A OF THE 2022 CALIFORNIA ENERGY CODE. <br />PIPE HANGER: <br />1.SUSPENDED PIPING MUST SATISFY WITH TABLE 313.3 HANGERS AND SUPPORTS OF THE 2022 CPC SEC. 313.3. <br />Scale: NTS <br />WATER HEATER PLUMBING CONNECTIONS DETAIL2 <br />MOLDED PIPE BOOT FURNISHED <br />BY ROOFING CONTR. <br />MEMBRANE ROOFING <br />SEALANT BEAD <br />STAINLESS STEEL PIPE CLAMP <br />SHEET LEAD FLASHING BOOT <br />MIN. 4 LB./S.F.
