The pressure relief valve of a water heater has a vital job – ensuring the water heater tank does not blow up.

We advise that at least two times a year, house owners test to make sure the pressure relief valve, or T&P valve as we will call it, is working appropriately. All one needs to do is raise the manage for a couple of seconds and let go of it. It should snap back to its initial position. When it is raised, one could hear the noise of pressure being released from it, just like the noise of air coming out of a tire pump when being disconnected. Also, a little water may come out also. Both are normal. If the valve has not been tested for a number of years, it may stick at first also.

Nevertheless, if the handle does not snap back, or if it remains to leak some water, that is not typical. If it still leaks some, lift the handle a couple of more times to see if it does re-seat itself. You might want to wait a day or so it see if it re-seats itself prior to presuming it has to be changed.

Water Heater Repair Corona would like to manage any T&P valve replacements for you, so though water heaters are usually relatively maintenance free, there are some safety preventative measures one should bear in mind. With that here is an overview of a pressure relief valve replacement.

1. The gas to the water heater has to be shut off, or the breaker for an electric water heater.
2. The cold water cut-off valve has to be closed .
3. The valve below the T&P valve has to be opened to drain a little water in order to relieve some of the pressure in the storage tank.
4. The overflow pipe of the T&P valve needs to be removed. It might have to be cut off if it is soldered or securely glued.
5. The pressure relief valve needs to be unscrewed with a pipe wrench.
6. Wrap the new T&P valve with Teflon tape and screw it back in place. Make sure the overflow pipe opening is placed away from the storage tank.
7. Reattach the drain pipe, also making use of new Teflon tape.
8. Turn the water back on, and examine your work for any leakages.
