Poly B Replacement

Poly B (polybutylene) plumbing was popular from the late 1970s – 1990s. But just like our hairstyles from those years, Poly B hasn’t stood the test of time. 

Normal plumbing things like water pressure, chlorine and UV cause the pipes to break down and rupture. We hate to bring the bad news, but this is important: Many insurance companies in Canada won’t cover damage caused by Poly B leaks. So it’s a good idea to replace your Poly B pipes before they cause problems.



This service is currently available in Calgary, Edmonton and the surrounding area. 



Since every project is unique, our pricing is all estimate based. Don’t worry though, you won't receive a surprise bill. We will go over the entire project's costs with you before the work begins.

  • What is Poly B? 

    Poly B (polybutylene) is a gray plastic tubing that was a popular choice for water-supply plumbing pipes in homes between 1978 and 1995. Unfortunately, water pressure, UV and chlorine in municipal water supplies caused the plastic to break down and rupture. 

  • Is Poly B still used? 

    Poly B was popular between 1978 and 1995, when it was discontinued after reports of pipes rupturing. Since then, copper or more dependable forms of plastic pipe (such as CPVC or PEX) are top choices. 

  • How do I know if my pipes are Poly B? 

    Not all plastic pipes are Poly B.  

    Poly B is a grey-ish flexible plastic. In some cases, it might be stamped with “poly B potable” or “PB2110” somewhere along the length of the pipe. Try checking the water supply lines under your sink or in your basement near the hot water tank to see if you can find the telltale stamp.  

    Other (and more home-friendly) plastic pipes like black ABS or PVC pipes or PEX pipes that can be white, translucent, red or black are good news for you and your plumbing. 

  • Why won’t insurance cover Poly B damage?

    Since 2005, insurance companies haven’t been legally obligated to cover Poly B damages, so most don’t.  

    In 2010, three class-action lawsuits were launched and have since been settled. Any compensation has been disbursed, so homeowners replacing their Poly B pipes may have to cover the costs themselves.
