PEX is basically a supple plastic pipe that is used for hot, cold indoor plumbing and for beaming floor heating. Installing a PEX is not as difficult as it seems, but a proper knowledge is essential. There are many plumbers who would suggest you some complicated way to install PEX and can charge a huge amount, but having a proper knowledge not only saves your time, but also your money. Below mentioned are the steps for installing PEX:


Step 1 – With a 90 degree angle drill the holes via wood wall studs and 1-¼ to 1 ½ inch spade make a hole. Make use of PEX hangers and straps to lock the PEX tubing to studs and other support configuration. In order to reduce the damage on fitting and to hold the pipe in the exact place, make use of hangers and straps.


Step 2 – Strand the tubing through the holes whereas an assistant will supply the pipe from a bigger roll. Now use the metal plates to the studs where the holes are bored, so that the screws and nails will not deflate the PEX tubing accidently when the walls are ceased.


Step 3 – Now slide a crimp/clamp ring over the tubing and add the end part of the pipe fitting into the pipe so the pipe end touches the shoulder of the PEX fitting. Slip the crimp ring over to the finish of the pipe leaving 1/8 and ¼ inch of pipe uncovered. By using the crimping/clamping tool, you can efficiently crimp/clamp the ring tightly to its place. However, one crimp is enough, but by making use of two, you can make the joint tighter.

Step 5 – Make sure that all pipes are installed in the above mentioned way. Turn on the main water supply and check if there is any leakage in the joints. Tight the joints carefully again and then test it.
