What is PEX pipe?
PEX is a cross-linked plastic (polyethylene) material manufactured with softer, and more flexible characteristics. It's been used in potable water and many other manufacturing applications all over the world since the 1960's, and gained significant traction in Europe in the 1980's. It's only somewhat recently caught on in the US, but is largely replacing more traditional piping materials in new construction and renovation projects.
