What is a TPR Valve on a Water Heater

A water heater temperature-pressure relief valve (TPR) is designed to turn off when the pre-set temperature is reached. If the water heater thermostat ever fails, the temperature and pressure (from expansion of the water) could continue to rise until the pressure exceeds the capacity of the tank (usually around 300 psi). If this happens, the tank could explode.

To prevent this dangerous situation, water heaters are required to be protected for both excessive temperature and pressure. A temperature and pressure relief valve (TPR). Most of these devices are set to operate at a water temperature above 200° F and/or a pressure above 150 psi.

It's important that a TPR valve only be tested by a trained professional. To make sure your water heater is working properly, it should be serviced annually by your plumber.
