PEX Explained

PEX — Cross-linked Polyethylene

PEX is a flexible plastic material made from medium- or high-density polyethylene. PEX piping has been used in hot- and cold-water distribution systems and for hydronic radiant heating in Europe for decades. Introduced into the U.S. in the 1980s, PEX is the most widely used flexible piping for plumbing and radiant floor heating applications. Due to its flexibility, it’s often a popular choice for remodels because it can be easily snaked through the walls. PEX tubing is recognized as acceptable for water distribution piping in all major model plumbing codes.
