Grey Poly-B supply lines in homes built between 1978 and 1995 become brittle and fail without warning. We replace them with PEX before they flood your home.
Poly-B replacement removes polybutylene water supply piping and its fittings and replaces them with modern PEX. Poly-B was installed in Canadian homes from the late 1970s to the mid 1990s and deteriorates as it reacts with chlorinated municipal water. Hayes Plumbing assesses, quotes and replaces Poly-B systems in homes across Durham Region, staging the work so water is only off for short periods.

A typical home takes a few days depending on size and how much plumbing is behind finished walls. We stage the work so you are not without water for long.
