Working with PEX
There are a lot of reasons why PEX (cross-linked polyethylene) plumbing pipe is so popular. PEX is less expensive than copper. It can be run in long lengths without any fittings, which reduces the chance of leaks. It’s less likely to burst in low temperatures. And the biggest advantage of PEX is that it’s super easy to work with. But just because it’s easy doesn’t mean you can’t screw it up. We asked Les Zell, our resident expert, to share some tips, preferences and techniques to help your next PEX install go as smoothly as possible.
Repair or replace kinks
Kinks happen. You can repair kinks with a heat gun, but some PEX brands tend to rekink in the previously kinked spot, especially if the pipe needs to make a bend at the kinked location. It’s best to cut kinks out and use the shorter sections of pipe elsewhere. If you get a minor kink in the middle of a long, straight run and you don’t want to cut it out, heat the pipe with a heat gun and then cover the damaged area with a hanger or abrasion clip. That will help the pipe keep its shape.
