The pressure relief valve of a water heater has a vital job – seeing to it the water heater tank does not blow up. So with that in mind, Water Heater Repair Carrollton wants to ensure property owners know the best ways to best care for it. They will leak when the valve wears out or when the water storage tank pressure gets higher then the relief point.Hot Water Heater Repair Carrollton TX

We recommend that at least twice a year, homeowners test to make sure the pressure relief valve, or T&P valve as we will call it, is working correctly. All one has to do is raise the handle for a few seconds and release it. It should snap back to its initial position. When it is lifted, one might hear the noise of pressure being released from it, much like the sound of air coming out of a tire pump when being disconnected. Likewise, a little water may come out also. Both are regular. If the valve has not been tested in a long time, it may stick at first too.

However, if the handle doesn’t snap back, or if it remains to leak a little water, that is not regular. If it still leaks some, raise the handle a couple of more times to see if it will re-seat itself. You could want to wait a day or so it see if it re-seats itself prior to assuming it needs to be replaced.

Hot Water Heater Repair Carrollton would like to handle any T&P valve replacements for you, so though water heaters are normally relatively upkeep free, there are some safety preventative measures one must bear in mind. With that here is an overview of a pressure relief valve replacement.

1. The gas to the water heater needs to be shut off, or the breaker for an electrical water heater.
2. The cold water cut-off valve has to be closed next.
3. The valve below the T&P valve needs to be opened to drain some 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 taken off. It may need to be cut off if it is soldered or firmly glued.
5. The pressure relief valve has to be unscrewed with a pipe wrench.
6. Wrap the brand-new T&P valve with Teflon tape and screw it back in place. See to it the overflow pipe opening is placed away from the storage tank.
7. Reattach the drain pipe, likewise using brand-new Teflon tape.
8. Turn the water back on, and examine your work for any leakages.
