How much does it cost to replace a pressure relief valve on a boiler?
Pressure Relief Valve Price A replacement valve costs around $20 and calling in a professional could bring your cost up to $200. This isn’t a steep cost to ensure proper diagnosis and installation. The pressure relief valve is there as a safety measure in case the pressure inside the tank gets too high.
How do I know if my pressure relief valve is bad on my boiler?
Signs Your Pressure Valve is Bad
- Flooding: Water should never be gushing from the valve.
- Excessive noise: If your water heater is rattling or emitting a high-pitched whistling noise, it’s likely the sound of steam trying to escape the tank, which is a sign of far too much pressure pressing against the inner walls.
How often should boiler pressure relief valve be replaced?

Why is my pressure relief valve leaking on my boiler?
If the system pressure is 30 psig and the relief valve, rated for 40 psig, is leaking, the relief valve is most likely defective. The most common causes are leaking gauge glass fittings above the water line of the tank, excessive system pressure, undersized tank, or the tank has a leak above the water line.
What would cause 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 do you fix a bad pressure relief valve?
Use a pipe wrench to unscrew the old pressure relief valve. Wrap Teflon tape around the threads of the new valve, and screw it in until tight, orienting the overflow pipe opening away from the tank. Reattach the relief valve drain pipe using Teflon tape on the threads.
How long should a boiler relief valve last?
As we mentioned earlier, pressure relief valves that are properly maintained can last for up to 30 years. In most cases, it’s important to look at the “why” behind pressure relief valve failure, rather than just replacing the valve in question.
