What is Poly-B Pipe?

Poly-B (polybutylene) (also known as ‘Poly-B Bad’) is plastic plumbing piping that was commonly used in homes built between 1978-1995 and has since been discontinued. Poly-B was popular for builders as it was much cheaper than copper piping, and it was installed in over 700,000 Canadian homes. It has a maximum life expectancy of 25 years but can fail much earlier than that.

What Is the Problem With Poly-B Piping?

Poly-b piping was discontinued several years ago because over time the pipes began to burst and leak. Many insurance companies will not cover you at all if this piping fails, and it can bring down the value of your home if you are trying to sell. With poly-b piping, it’s not a matter of IF it will fail, it’s WHEN it will fail and you don’t want to wait until it happens.
