Why is my PRV leaking?
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.
How often should a pressure relief valve be replaced?
If the valve does not lift upwards with slight pressure, or it lifts but there is no corresponding heat or running water, then the TPR is faulty. This test should be performed before regular maintenance, or at least once a year.
Can a relief valve be discharged before installation?
 Do not discharge relief valves prior to installation or when pressure testing the system.  Use the proper size and length of discharge tube or pipe. Correct sizing is required to prevent back pressure from building up in the discharge line, preventing the relief valve from discharging at its rated capacity.
How does a pressure relief valve work on a water heater?
All water heaters have a safety valve designed to release excess pressure from the tank in the event that the water gets too hot. This valve, often called a TPR valve, prevents the tank from building excess pressure. Need to hire a plumber? Get a free estimate online from top local home service pros in your area.
What makes a safety relief valve lower in pressure?
These impurities are generally blown into the relief valve seats at the time the valve is discharged. The impinged debris then inhibits the relief valve from reseating at its original set pressure. Valves are then found to relieve at considerably lower pressure settings than the stamped valve setting, due to the force of the reclosing action.

Why does my pressure relief valve keep opening?
Pressure relief valves are designed to open to relieve pressure in your system and then close again. In a clean environment, they may be able to open and close multiple times with no problems. But, in some cases, when a valve opens, debris can get into the valve seat, which can prevent the valve from returning to its original closed position.
What causes the fuel pressure relief valve to fail?
One other part on a common-rail 5.9 that’s known to fail would be the Fuel Pressure Relief valve. Whether the valve seat becomes jammed with dirt or the internal spring has failed, the result is a valve that is stuck open and little to no rail pressure, since all the fuel will be returned to the tank.
