The truth about polybutylene piping

Polybutylene, also known as Poly B, is flexible grey plastic piping that was commonly used in residential homes from the 1970s until about 1995. Poly B piping was viewed as a great residential plumbing material, and an alternative to copper piping, due to it being very inexpensive to produce and easy for plumbers to install.

Polybutylene piping is found in areas—like BC—where residential construction was heavy through the 1980's and early-to-mid 90's. In the Okanagan, typically only homes built between 1978 and 1995 have polybutylene piping in them.
