An 84-gallon gas water heater in Clarksburg started leaking, and the homeowner needed help the same day. Our technician came out that evening and replaced the temperature and pressure (T&P) relief valve.
The problem
The homeowner's 84-gallon gas tank water heater had been leaking for about an hour when they reached out. The leak was at the T&P (temperature and pressure) relief valve, and they wanted someone out the same day.
What our technician found
The T&P relief valve is a safety valve on every tank water heater. It opens to let out water if the temperature or pressure inside the tank gets too high. A valve that keeps dripping or leaking is either worn out or opening because the pressure or temperature in the tank is getting too high, so it should be looked at right away. Never cap or plug a leaking relief valve.
What we did
- Came out the same evening the homeowner called.
- Replaced the leaking T&P relief valve on the water heater.
Parts used
- Temperature and pressure (T&P) relief valve
The result
The technician replaced the T&P valve and finished the job that evening.
Tips for Clarksburg homeowners
- If water is coming from the relief valve or its discharge pipe, turn off the gas to the heater (set the control to Off or Pilot) and close the cold-water supply valve, then call a plumber.
- Never plug, cap or remove a T&P relief valve. It protects the tank from dangerous pressure.
- A relief valve that opens again after being replaced can point to high water pressure or a missing or failed expansion tank. Ask your plumber to check both.
- Lifting the T&P valve lever once a year shows whether it still opens and closes. Stand clear of the discharge pipe, because the water is very hot. If the valve won't reseat and keeps dripping, it's time to replace it.
