Minimizing Potential Water Heater Dangers

The most crucial maintenance activity having a water heater is to test the pressure relief valve, referred to as the T&P valve, on a usual basis. This valve helps control the pressure accumulation inside of the water storage tank to protect against a serious rise in temperature and overpressure.


Be careful, the water release out of a T&P valve might be really hot. If you do not feel comfortable evaluating the valve let us know. Additionally, carrying out any kind of repairs to the valve should be completed by a expert plumbing repair provider.

How to Test the T&P Valve

Remove anything from around the area near the overflow pipe and floor drain.

Lift the test handle for about 5 seconds or until the water runs clean.

Release the handle.

If the T&P valve continues to run with water, raise the handle up and down quickly to have it reseat itself. One may need to do so a several times. IF it has not been tested for a while, it might be difficult to raise it at first. Avoid using too much force, but could need to use a little.

If the T&P valve remains leaking, it should really be replaced.

Other points to look for are corrosion on the stem of the valve. If there is any water dripping out of the valve stem or from the drain valve.
