The installation of chlorinated polyvinyl chloride(CPVC)pipe for water distribution systems must meet the <br /> following requirements(see Minnesota Rules, part 4715.0520): <br /> a. Pipes less than 21/2-inch in size must comply with ASTM Standard D2846. <br /> b. Pipes 21/2-inch to 6-inch in size must be schedule 80 and must comply with ASTM Standard F441. <br /> c. Solvent weld joints must either include the use of a primer which is of contrasting color to the pipe and <br /> cement or a one-step solvent cement complying with ASTM Standard F493 and ASTM Standard D2846 <br /> (see Minnesota Rules, part 4715.0810, subpart 2). <br /> d. The installation must be in accordance with International Association of Plumbing and Mechanical <br /> Officials(IAPMO)Installation Standards 20 98. <br /> If CPVC will be used for the water distribution mains, the water sizing may not be adequate due to the <br /> reduced inside diameter of the pipe relative to copper pipe. Accordingly,the design engineer must ensure <br /> that the water sizing meets the minimum requirements of Minnesota Rules, part 4715.3700 for the reduced <br /> inside diameter. <br /> 28.
