I have a friend with poly-b water lines in his house and he's having a company replace every single water line due to the high failure rate. I had no idea that type of pipe was so prone to failure but I guess it's serious enough that a lot of people are paying to have drywall cut open and everything replaced.
Has anyone here had this done? I'm curious how the old line is removed and how much drywall needs to be cut open, especially with clips nailed to the studs used to secure the original water line during installation. How do they fish the new line?
