Watch a quick video with each tip to see how it’s done
If you’re working with PEX-a pipe and you get a kink, simply use a heat gun on the area and rotate the heat around the kink until the pipe turns clear. As the pipe cools, it will return to its original opaque color, and you can continue with your installation. (Note that kink repairs are only possible with PEX-a pipe; you cannot kink repair PEX-b or PEX-c pipe.)

Use bend supports
PEX-a pipe is extremely flexible (3X the pipe’s diameter), so save yourself time and money by bending the pipe with each change in direction rather than using an elbow. Bend supports are also available to help keep the pipe in place.
Watch this video to see how bend supports and other tools are used in a PEX system.
Install pipe clamps or tube talons
When running PEX main lines, it’s important to support the pipe properly with pipe clamps or tube talons. Place supports every 32″ in horizontal runs and every 5 ft. in vertical runs.

Make proper expansion connections
When making an expansion connection with PEX-a pipe, ensure you’re making a straight, square cut. This ensures the expansion ring will seat properly on the end of the pipe. Then, when you insert the expansion tool, make sure the tool is auto-rotating. If you’re using a manual tool that does not auto-rotate, but sure to rotate the tool with each expansion. Failure to rotate the tool will leave deep grooves in the pipe and can cause leaks.

Maximize efficiencies with multiport tees
What’s a multiport tee? It’s a molded tee with multiple outlets to minimize connections in a plumbing system and increase installation efficiencies. For example, if you’re installing six regular tees, you will have 18 connections. But a six–outlet multiport tee will only have eight connections (six connections for the ports, a main flow-through inlet and a main flow-through outlet).
