How to test your water heater's temperature and pressure relief valve

The temperature and pressure relief valve on your water heater is a crucial component of your water heater that should never be removed or disabled. It should also be tested periodically to ensure that it's working properly.

Relief valves usually discharge for one of two reasons:
- excessive pressure buildup over 150 psi
- temperature inside the tank exceeds 210 degrees F

In either of these cases, the pressure relief valve will open to prevent an explosion. If you notice water around your water heater and there's no sign of a leak, it's likely that your temperature and pressure relief valve has recently opened.

In addition to ensuring that your house has an ideal range of water pressure coming in from the main, you want to make sure that your thermostat on your water heater isn't set too high. It's a good idea to test your valve at least once a year to ensure it's not being blocked by sediment buildup.
