Why is water coming out of the pressure relief valve?

When you see water coming out from the water heater release valve, there are two most likely causes. The relief valve is working the way it’s intended, and water drained to reduce the pressure inside the tank. There’s a problem with the valve, such as a faulty seal, and the water is unintentionally leaking.

Signs Your Pressure Valve is Bad

1. Flooding: Water should never be gushing from the valve.
