Two Things to Keep in Mind When Using PEX Plumbing Pipe

Whether you’re a homeowner making a DIY repair or a professional plumber working on a new installation, it’s vital to understand the nuances between different pipe materials and products. Mismatched or inadequate components in a plumbing system can lead to leaks, reduced flow or even system failure.

If you’re looking for an alternative to traditional copper or galvanized steel piping, PEX may be the right choice for you. It’s flexible, easy to work with and carries water at high pressure without requiring the frequent re-tightening of connections like copper pipes. Here are two things to keep in mind when choosing and using PEX plumbing pipe:

PEX is made from cross-linked polyethylene. During cross-linking, the molecular structure of the polyethylene is changed, which improves its elevated temperature strength and performance as well as its resistance to slow crack growth.

It’s also safe for potable water, tested to NSF/ANSI 61. It’s BPA-free, which means it won’t leach chemicals into your drinking water.

PEX is less expensive than copper piping but still offers the same water pressure and quality. It can be used both indoors and out, but it’s important to insulate it before burying it underground or running it through concrete slabs. Keeping the outside temperature above freezing will also help avoid damage to the pipe. Rodents are notorious for chewing on PEX, so be sure to store it inside and away from the sun’s UV rays. It’s also a good idea to leave a little loop of pipe on long runs of PEX supply to allow for expansion and contraction. pex plumbing pipe
