Water Heater Parts

Water heater service parts, most of them relief valves: Cash Acme and Campbell temperature and pressure relief valves in bronze, brass and stainless steel, in 1/2 and 3/4 in. threaded. The T and P valve is the safety device on the tank, and a valve that weeps is telling you something — one that has never been tested is worse. Pressure-only relief valves belong on systems where temperature is controlled elsewhere; they are not a substitute for a T and P on a water heater. Match the thread size and the set pressure stamped on the old valve, not just the pipe size.
