My Water Heater Pressure Release Valve Is Leaking – What Should I Do?

Updated: Dec 16, 2021

If you’ve noticed water pooling around your hot water heater, this may be because of the water heater pressure release valve. Wondering what this means, and what you should do about it? Find out now!



Where Is the Water Heater Pressure Release Valve?


The water heater pressure release valve is attached to the upper portion of your hot water tank.


It typically consists of a valve that attaches to the side of the tank with a long copper tube or PVC tube that runs vertically downward, allowing water to drain out of the valve when necessary.


If you are having trouble finding the valve on your unit, or cannot identify it, we recommend searching for the make and model of your water heater on the internet. The manufacturer’s schematics and manuals will help you locate the water heater pressure relief valve.


What Is the Water Heater Pressure Release Valve & What Does It Do?



The water heater pressure release valve, also known as the “temperature and pressure” (T&P) valve is a valve that helps control the pressure and temperature of your water heater, preventing it from overheating, becoming too highly pressurized, and potentially exploding.


The way this valve works is by sometimes letting a little bit of water drip out of the tank. When there is too much pressure inside the tank, the valve opens up to relieve this pressure and some water will drip out of it. This is normal, and indicates that the valve is functioning properly.


However, if your water heater pressure release valve is constantly leaking a lot of water, the water contains debris, or your valve is making a lot of noise like whistling and screeching, this may indicate that it has failed, and is not operating properly.
