Email. Polybutylene piping is a form of plastic resin and was commonly used for plumbing U.S. homes built between 1978 and 1995. Due to its inexpensive production cost and ability to withstand high water pressure, it was widely seen as a better, cheaper alternative to copper plumbing.nfortunately, if there are polybutylene pipes within the home, or leading into the home, the best course of action is to replace the pipes entirely by hiring a re-pipe specialist. An expert can assess the current plumbing, replace the pipes and expertly patch up any holes.
The previous three plastic pipe variants are all rigid whereas PB (polybutylene) and PE (polyethylene) are flexible; the former being rigid and used for the same purposes as CPVC and the latter being low cost. Both of these types are not joined with solvents but are instead formed with mechanical and clamped couplings.
