leaking on the hot water system. Now what do you do. Well read on and follow this guide about hot water pressure relief valve replacement and how easy it is.

Things you need to do this simple job

First of all make sure you replace the ptr valve with like for like. If you are not sure then read this post about water heater pressure relief valve before going any further. Once you have the correct hot water ptr valve you will also need thread tape and adjustable spanner.

Make sure the water to the hot water heater is turned off and isolated. You can turn the power off if you have a electrical system or turn the gas off to if like. It’s not that important as the hot water pressure relief valve replacement wont take long to do.

Now that the water is off open up the new valve and apply thread tape around the brass thread. Go around the thread some where around 16 to 18 times making sure you apply it in a clockwise direction. Once that is done pull the lever on the old water heater pressure relief valve to release any pressure in the tank. Loosen off the brass nut that holds the copper drain onto the valve and unscrew the hex nipple that the nut screws onto. Thread tape the hex nipple same way you thread taped up the pressure relief valve and screw it into the new valve.

Remove the old pressure relief valve with your adjustable spanner. There will be either flat side area along the body of the valve on opposite sides to each other or a nut shape near the lever that you pulled to test the valve. Once its all the way out a little bit of water will come out with it nothing to worry about and just screw the new valve in.

Tighten up the valve and making sure the outlet is facing down like the old one was and reattach the drain pipe. Go inside and open up hot water tap then turn the water on to the heater. What this does is removes any air in the line that entered when replacing the valve. Once the water is running free through the tap turn the tap off and check the new valve for leaks. If all good and no leaks turn the gas or power on if you turned it off and that’s it. This is a very simple way to replace a hot water pressure relief valve.
