We just bought and moved in a late 1980s home that we haven’t hooked the utilities up to yet.
Our handyman was looking at it, and said all of the plumbing lines are gray plastic, which is bad.
After doing a quick google search it appears this is polybutylene piping.
Our handyman is recommending that while the home is blocked up with skirting off, it would be much easier to just replace all of the plumbing lines with pex. Waiting would likely lead to frequent water leaks down the road, which will be much harder to repair once the home is skirted and closed up.
After some research it appears much of polybutylene was junk, but there was some variability in quality. I’m considering hooking up the water lines, seeing if there are any current leaks, and if there are replacing the whole system, and if not closing it up and keeping my fingers crossed. Any thoughts?
