How to Install PEX Valves
Installing pex valves sounds like a daunting task. However with a few easy steps you can get the job done quickly.
Step 1 - Prepare
The first thing that you will have to do is shut off any water supply and power that you have through or near the pipe that you are working on. Then you will want to drain the pipe to make sure that it does not leak as you are working. You can do this by either turning on the faucet and letting the water remains drip out or using a wrench to loosen the pipe and clear it out and then reattach it.
Step 2 - Cut The Pipe
Using the PEX clamping pipe cutter you will want to make a cut in the PEX pipe. Make sure that when you are cutting you do not do it on an angle and rather in a square manner.
Step 3 - Sand The Pipe
Now that it is cut you can take the piece of fine sand paper and sand any rough edges that you may find on the pipe or around the area that you cut. Make sure that while you are sanding you do not remove too much of the pipe or sand too aggressively.
Step 4 - Measure
You can now measure an inch from the cut that you made and mark it with the marker. This will let you know how far you will have to push the new valve when you get it on.
Step 5 - Install the PEX Valve
Now that you have set the mark to where you need to push the valve you can actually install the valve. Take the valve and push one of the sides back as you move it up the pipe. Make sure that you move it to the spot and that it is secure as you go. Now that you have the first part of the valve on you can leave just an inch on the end and then cut the rest of it off. Once you have made the cut using the cutters from before you can sand with fine sand paper any rough edges that may be a result of the cut. Again, measure and mark like before 1 inch to make sure that you have the correct distance for this valve. Now you can take the other part of the valve and push it firmly until you reach the mark that you made and then secure it.
Step 6 - Turn Water Back On and Test
Now that everything is hooked up you can turn the water and power back on to that area and test to make sure that there are no leaks.
If you do come across a leak then you can turn the water back off and then refit the valves to make sure that they are on tightly and sealed.
