PEX water pipes are made from cross-linked polyethylene. This material makes for strong and flexible water lines. PEX water pipes come in red, blue and clear. According to Dallas plumbing company experts, the practice is to use red for hot water lines, blue for cold water lines and clear for heating systems that go underneath the flooring. Because PEX lines are flexible, they are attached to fittings whenever a water line needs to take a turn. They can also be installed as a main line with several others branching out. PEX water pipes can use two kinds of fittings: crimp fittings or quick connection fittings. If you do not have a special plumbing tool known as a crimper, Atlanta plumbing company experts advise that you simply use quick connection fittings instead.
Measure and cut the length of PEX pipe that you need. Unlike stiff pipe materials such as copper, you do not have to cut one length for one direction. Since PEX pipes are flexible, you simply need to use 90-degree corners to bend it into another direction when the water line needs to turn. To cut the PEX pipe, hold the tubing cutter at a 90 degree angle while squeezing it and turning in a circle. The cutter will cut through the pipe as you continue to squeeze and turn.
To install the quick connection fitting, push the PEX tubing into the opening as far as it can go. Some resistance will be met so you will need to push firmly. Stainless steel teeth inside the fitting will grasp the tubing and hold it in place. Before you insert the end of a PEX tube into a fitting, make sure that it is burr-free so that it will fit correctly and will not leak. You can use a pocketknife to remove burrs from the end of the tubing.
Try to pull the tubing and fitting apart just to check whether the fitting is properly seated on the PEX pipe. You shouldn’t be able to move the connected parts. If the tube moves out, push the collar towards the fittings so you can pull the tubing out and release the collar. Insert the tubing deeper into the fitting.
