How to Plumb a PEX Water Supply System Part 1 How to Plumb a PEX Water Supply System Part 1
If you need to plumb a cross-linked polyethylene or PEX water supply system, then you will need to learn how to install the pipes and connections. Applying some PEX to your water supply system will allow you to get a good flow of water through durable pipes that are flexible, and also resistant to water. In Part 1 of this guide, you will learn how to fit the manifolds that are used to connect the pipes to the PEX system, add supply lines to these manifolds and anchor them to frames. To install the pipes, you will have to do a lot of work to get the pipes into the right place. With some basic home improvement plumbing skills and a few tools, you can follow the simple steps below to complete this project in a few hours.
Step 1 - Fitting the Manifold
Add a manifold to the copper or iron pipe at the start of your water supply system. The manifold is a series of valves that connect the pipes into the supply lines. You should also install the manifold into the edge of the pipe by pushing it onto the edge, and then tightening the sealing bolt using a wrench to tighten the nut. You should be able to tighten this into place.
Step 2 - Adding the Supply Lines
Once the manifold fittings are in place, you can then add the flexible supply lines to them using the same screw in method. Take the fittings, and then push them into the manifolds. You can push as many supply lines as you can fit it into the manifolds. You will be able to screw it into the valves. You will be able to make the valves fit into the manifold by loosening and then tightening the screw connections. Once the supply lines are fitted into the manifold, tighten up the screw fittings. You might want to use a wrench to make sure that these connections are completely tightened.
Step 3 - Fitting the Manifold Onto the Frame
Once you have added the supply lines to the manifold, you can push them into the frame fittings. Secure these to the frame parts using the connections at the back. These will keep the manifold in the right position, and from there you will be able to secure all of your pipes and lines in one place.
Once you have finished fitting the manifold onto the framing lines, check the seals on both the pipes and the supply lines. Make sure that all of your pipes are suitably tightened before you start connecting the rest of the plumbing as this will ensure that you do not have to go around at the end and secure the pipes. Use your wrench to get all of the fittings extra tight.
