If you want to install a thermostatic valve at copper water pipes, it is recommended to hire a professional service. This is because copper water pipes are difficult to deal with and only professionals could do it more effectively. However, if you want to install it on the galvanized pipes, you can easily do it at home by yourself. In order to do so, make sure to follow these important steps one by one.
Step to Follow
Step1 : Check the water heater thermostat control first. If it is on, turn it either off or at the pilot position.
Step 2 :Similarly, also close the cold water inlet valve to stop the flow of cold water during the procedure.
Step 3: Even though the supply of water is stopped from their inlet points, the water is still available in the water/sanitary pipes. Turn on the taps of faucets in your home so that all of the standing water in the pipes could be drained. In this way, the pipes would be set free of water and the supply of hot/cold water would also be stopped.
Step 4:The water that is present in the heater would be very hot. Give it some time i.e. one to two hours to cool down to a lesser temperature.
Step 5 :Detach the vent pipe from heater top by lifting up the flange that is located at the bottom side of vent pipe. Put both of these (flange and vent pipe bottom) towards the heater backside in a slow direction and smooth movement.
Step 6 :Loose and detach the top fitting of cold water flex line with the help of a right sized wrench. After that, simply detach this fitting from its connected shutoff valve.
For cold water connections:
step 1:Take the vinyl plumber tape and wrap it completely around the underside threads of shutoff valve. Hold the galvanized couple and screw its female end onto threads. Then take a wrench and rotate the coupler clockwise to tighten it firmly.
step 2:You will see the blue colored plastic cap at the cold water inlet threads. Carefully pull them off from the upper end of these threads and cover them through wrapping a vinyl tape around them.
step 3:Now, pick up the valve with hand and at the same time, and screw the coupler’s male end inlet carefully. Now, properly tighten the fitting by using both of your hands, and an adjustable wrench.
For hot water connections:
step 1:From hot water pipe, loosen the fitting at the top of hot-water flex line and simply detach aside it in one direction.
step 2:Just like we did in cold water pipes, wrap a vinyl tape at threads of hot water pipes. Then pull of the red plastic caps at hot water pipe inlets but make sure to perform this step at the lower end of hot water pipes.
step 3:Take a wrench and open the shutoff valve at the side of cold water connection.
step 4:Now, connect back the vent pipe. Now, turn on the water heater and allow the water to come in. set the temperature and let the heater heat the water for about one hour.
step 5:After that, when you open up the tap, the new adjustments in the pipes and mixing valves would make the water temperature constant for you. In this way, you can easily get the water of required temperature at any time in your home.
An important thing to consider!
While sealing the pipes or threads, make sure to use only the vinyl plastic tape instead of sealants. If you use the sealing compounds on threads/pipes during the process, there are higher chances that the sealant traces would mix in water. They will get inside the hot water pipes and contaminate your water. Furthermore, it wouldn’t be as durable as vinyl plastic tape when it comes to sealing the hot water pipes.
