CPVC Now Used for Water Heater TPRV Pipe Extensions

Recent information about CPVC supply piping indicates that it has been tested and found capable of withstanding prolonged bursts from a water heater TPRV. According to information on the Plastic Pipe and Fittings Association web site, CPVC systems are tested at 150 PSI (pounds per square inch) and 210 Fahrenheit for a period of 48 hours. Based on this new information, U.S. Inspect has changed its reporting policy to reflect CPVC as a proper material for water heater TPRV pipe extension applications.
