How to Open a Water Heater Pressure Relief Valve

Are you wondering how to open a water heater pressure relief valve? For most homeowners, tinkering with the water heater tank can feel a little nerve-wracking. However, opening a pressure relief valve is one task that is relatively straightforward. The most difficult part of the task is finding the hot water heater pressure relief valve on your specific model. Keep reading for the information you need to find the valve and open it.

How to Find the Water Heater Pressure Relief Valve

Also known as the temperature/pressure relief valve or the TPR valve, this valve is located near the top of the water heater. It usually features a lever you can lift up or down and has a discharge pipe that runs from the valve down to the water heater’s base. If you aren’t sure where to find the valve, refer to your water tank owner’s manual.

The purpose of this valve is to release water, thereby, lowering pressure in the water tank. Without the water heater pressure relief valve, the pressure within the water tank could become higher than the tank is meant to handle, which could result in an explosion. Testing the valve annually is an important task to maintain the safety and optimal function of your water heater tank, which is one reason why scheduling regular professional maintenance with your local Mr. Rooter^® Plumbing is a good idea.
