What to do if pressure relief valve is leaking?
Common Fix For a Leaking Temperature Pressure Relief Valve
- Turn off the water heater breaker.
- Shut off your water.
- Empty the water heater by draining the bottom and water inside your home.
- Remove the TPR valve and discharge tube by unscrewing with a wrench.
- Replace with a new TPR valve and discharge tube.
Why is my pressure release valve 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.
Does a pressure washer have a pressure relief valve?
Replace the pressure washer thermal relief valve The thermal relief valve opens to release hot, high-pressure water from the pump system onto the ground to prevent damage to the pump. If the water gets too hot, the thermal relief valve opens to relieve the pressure by dumping hot water on the ground.
Is it normal for a pressure relief valve to leak?
Your water heater’s relief valve can start leaking for one of two reasons: either the valve was triggered to open because of excessive temperature or pressure, or the valve itself is faulty. If the problem is a faulty valve, then you might have an actual leak.
How much is a pressure relief valve?
How Much Does a Pressure Reducing Valve Cost? Pressure reducing valves start at around $50. Having a new pressure reducing valve installed by a professional plumber will probably set you back around $350. If you’re more of hands-on, DIY-type homeowner, you can purchase one and install it yourself.
How often should a pressure relief valve be replaced?

How do I know if pressure relief valve is bad?
3 Signs Of Pressure Relief Valve Failure
- System Cannot Reach Pressure. If your system isn’t reaching pressure, this could be a sign of pressure relief valve failure.
- System is Over Maximum Pressure.
- Pressure Relief Valve is Leaking or Has No Pressure.
What causes a pressure relief valve to leak?
Recently there have been several claims against ‘leaking’ TPR valves. Upon testing it has been found that the relief valve is neither passing nor failing to reseat, the ‘leak’ appears to be water passing out of the blow-out cage which has opened when the easing lever has been operated too quickly during maintenance.
What causes a hot water cylinder to leak?
Incorrectly sized or partially blocked relief drains causing back pressure may also cause the blow-out cage to activate again releasing water at the cylinder. The relief pressure of the blow-out cage is roughly 50% of the pressure rating of the TPR valve.
Can a pressure relief valve be cut off?
Cutting it off will only need to be done if your valve has been soldered or glued on. Otherwise, it should come right off with little to no issues. Once you have your overflow pipe removed you will then be able to get out your pipe wrench and unscrew your old pressure relief valve.
