{"title":"Water Heater T\u0026P Relief Valves","description":"\u003cp\u003eA water heater temperature and pressure (T\u0026amp;P) relief valve opens to release water if the tank gets too hot or the pressure climbs too high. It is a required safety device on every storage water heater, and a valve that drips, sticks or has been in service for years should be replaced.\u003c\/p\u003e\n\u003cp\u003eThis collection lists the water heater T\u0026amp;P relief valves we carry from Watts, Cash Acme, Zurn Wilkins, Apollo-Conbraco and Rheem. Most are 3\/4\" valves for residential tanks, with 1\" and 1-1\/4\" models for larger heaters. You can choose 125, 150 or 175 psi pressure settings, lead-free or brass bodies, test levers, and extension thermostats or extended shanks for tanks with thicker insulation.\u003c\/p\u003e\n\u003cp\u003eTo pick a replacement, match the connection size, the pressure setting and the BTU\/hr rating to the water heater's data plate, and make sure the sensing element will reach into the tank. Pipe the discharge to an approved drain as required by your local code.\u003c\/p\u003e\n\u003cp\u003eLooking for boiler or vacuum relief valves?
