Need a Primer on PEX

Apr 10, 2007 4 Replies

How long has this been around, and what are the advantages over 1" black polypipe? Will it crack when frozen? Can it be buried and used as a line from a well to the house? Thanks. Frank


It has been around in Europe for about 40 years. It is more flexible than some of the other plastic pipes. It will expand a bit with a freeze, but it is still possible to crack it. I don't know about burial requirements or codes. A Google search will turn up plenty of information.

Here's a FAQ

Hi, Between well and house? Are you using the well seasonal? Otherwise risk for freezing solid is minimal even with black poly stuff. I have it out at my 4 season cabin. After 8 years, it's still working.
