Hot water heater pop off valve.

My hot water heater is leaking from the pop off valve i have replaced it several times and now i have a new heater and guess what it is leaking through the pop off valve. If the water heater thermostat fails to turn off at its temperature setting and continues to heat the water indefinitely the tpr valve will open and let the overheated water out. Open the valve at the bottom and the pressure relief valve for a minute to drain a little. The second reason a water heater relief valve leaks is the water has gotten too hot if the temperature of the water in the water heater reaches above 210 degrees f the relief valve will leak or even blow off this is why the outlet of the relief valve must be piped to about 6 inches from the ground you would not want to get a blast of 210 degree f water in the face.

First turn off the gas to the water heater or flip the breaker if it s electric. But if the termination of the piping is not readily visible such as if it is located under the house the water will continue to drain until the homeowner gets an amazing electric or gas bill and goes searching for the reason. I have had 4 different plumbers check this out they put a new regulator at the water meter turned the temp of the water down replaced every thing in the old heater. These valves may look identical but they re set to go off at 30 psi not 150 psi.

If a new tprv is properly installed and it still leaks you probably have a pressure problem. 4 6 out of 5 stars 445. Free shipping on your first order shipped by amazon.
