Water Leaking From Water Heater Pressure Valve

This valve allows water or steam to escape from the water heater if the temperature or pressure gets too high.

Water leaking from water heater pressure valve. So when there s a lot of pressure being built inside our electric water heater pressure relief valve it will eventually start leaking water outwards. If the relief valve is needed frequently that means there s an issue with. Open a hot water faucet near the heater to release pressure and drain the tank until the water level is below the valve. This prevents a water heater from exploding or turning into a missile.

1 either the water pressure inside the tank is too high 2 the water temperature is too high 3 the t p valve hasn t been used in a few years 4 the wrong t p valve was installed or 5 the t p valve itself has failed. When a tprv at. To remove a t p valve first turn off the electricity or gas and wait for the water to cool which usually takes about 24 hours. Both circumstances should be taken very seriously.

Technically speaking when a water heater warms the water inside the tank it builds up quite a good amount of pressure. When you see water coming out from the water heater release valve there are two most likely causes. When water is coming out of the pressure relief valve on your water heater it could signal that too much pressure is building up inside the water heater which is what the valve is designed for due to the burner or element not cutting off in which case the water heater needs to be repaired or replaced. Disconnect the overflow tube you may have to cut it and unscrew the valve with a wrench.

This extra amount of pressure causes the water to expand although it s a closed system that we have in electric water heaters. The relief valve is working the way it s intended and water drained to reduce the pressure inside the tank.
