What is a TPR extension?

Temperature/pressure-relief or TPR valves are safety devices installed on water heating appliances, such as boilers and domestic water supply heaters. TPRs are designed to automatically release water in the event that pressure or temperature in the water tank exceeds safe levels.

A valve used for clean service, such as steam, can last a long time — easily 20 years if it isn’t operated too close to the set point and gets the right preventative maintenance program.

You can’t use any PVC inside the house, and specifically never on water over 70º. You can use CPVC, but it is not recommended to connect that directly to the water heater..you need about 18″ of copper to keep the high heat off the plastic.

What is CPVC pipe?

Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin, which is significantly more flexible and can withstand higher temperatures than standard PVC. Uses include hot and cold water delivery pipes and industrial liquid handling.
