Installing The Tempering Valve
Tempering valves mix hot water with cold water so the water that comes out of your shower head doesn’t freeze or scald you. Tempering valves are responsible for the warm water to which you look forward to coming home. There are a number of tempering valves that are available for different heat tempering requirements.
The tempering valve isn’t that difficult to install, especially if it will be connected to your existing electric heater, but call a professional if you’re not sure. All plumbing as well as electrical installation work should be carried out by a competent person in that case.
Installing the tempering valve would require certain necessary tools and materials like tempering valve, 2 pipe wrenches, pipe cutter (for new installation), Teflon tape, section of water pipe (for new installation) and 2 T’s (for new installation).
Turn off the water to the water heater by turning off the valve to the heater. Drain the water heater using an electric pump and garden hose. Also, close the valve to the hot water heater.
Take out the old and damaged valve using the pipe wrenches. For a newer installation, cut out a short section on the cold water supply line and the hot water supply line to allow for the T’s.
Install T’s in each of the two supply lines by following manufacturer guidelines for installation. A small portion of pipe is to be cut leaving some space for the tempering valve.
Affix the tempering valve to the section of pipe cut previously. Join this portion of pipe to both the cold and hot water supply lines. Use the same procedure to install the T’s as you have installed the T’s. Secure the pipe joints with Teflon tape. This will prevent the water leakage. Make use of the pipe wrench to tight the pipe joints. However, over tightening them, can damage the joints.
Turn the water back on. Test the valve by turning on the heater. Adjust the knob of the tempering valve to set the temperature as per the requirements.
