Water Pressure Relief Valve Leaking

The relief valve is an important safety feature on the water heater.

Water pressure relief valve leaking.

Why is your water heater pressure relief valve is leaking before testing. Just replace the valve. If at any point the temperature or pressure reaches an. As a general rule we can say that if the temperature relief valve has a defect in functionality then your tank is more likely to be a victim of some sort of a.

The pressure relief valve also as known as a blow off valve is a vital component of a boiler. An important safety component of your water heater the temperature and pressure relief valve is required by every plumbing code.

Extreme pressure within the system could cause the boiler or water lines to rupture. In the first case the valve will drain water out of the discharge pipe as explained above.

In the event that the temperature of the water in the tank rises above a preset value usually 210 degrees fahrenheit or the pressure rises above 150 psi the valve opens thereby averting a possible explosion. When a temperature and pressure t p relief valve at a water heater leaks it s usually a simple fix.

Either the valve was triggered to open because of excessive temperature or pressure or the valve itself is faulty. That depends on whether the pressure relief valve is leaking around the threads where it attaches to the hot water tank or if it is leaking out of the inside of the valve itself.
