The temperature and pressure relief valve tpr valve opens to release pressure buildup in the water heater when the temperature or the pressure get dangerously high preventing a possible explosion. 1 shut off the cold water to the water heater and gas or electricity that heats the water heater. 2 drain the water from the tank until the water level is below the valve s location.

Rheem protech 4 1 4 in. The valve should always be in good working order to ensure the water heater is safe in the event of extreme pressure buildup. Here s how to replace a water heater temperature pressure relief valve. Make sure that the water temperature setting is in the normal recommended range about 120 degrees f or no more than about 150 degrees f.

T p valves used on residential water heaters are typically designed and manufactured to relieve pressure at 150 psi and temperature at 210 degrees f. Water heater temperature and pressure relief valves or t p valves are a safety feature found on all tank water heaters. Close the shutoff valve on the cold water inlet line that fills the water heater. A buildup of mineral salt rust and corrosion can cause a tpr valve to freeze up and become nonoperational.

The last line of defense for pressurized equipment temperature and pressure t p relief valves protect equipment from excess pressure and ultimately catastrophic failure. A water heater that periodically discharges hot water and steam from the t p valve may be set to a water temperature that is too high. Water heaters come equipped with a temperature and pressure relief valve also known as a tprv. If the water heater thermostat fails to turn off at its temperature setting and continues to heat the water indefinitely the tpr valve will open and let the overheated water out.

This valve allows water or steam to escape from the water heater if the temperature or pressure gets. Rheem protech 5 1 4 in. Asme ansi and csa aga approved relief valves protect the water heater from excess pressures and temperatures by discharging water. Set your store to see local availability.
