Poly-B (polybutylene) pipes are known to deteriorate over time, making them highly susceptible to leaks and sudden pipe failures. These issues can cause extensive water damage and result in thousands of dollars in costly repairs for homeowners throughout Victoria. Replacing Poly-B piping is an important step in eliminating a major plumbing safety risk and protecting your home’s structure.

Thunderbird Plumbing brings decades of experience planning and completing complex Poly-B replacement projects across Victoria and the Greater Victoria area. Our team ensures the job is done safely, efficiently, and with minimal disruption to your home.

The Signs You Have Poly-B In Your Home

The first step in replacing Poly-B in your home is identifying Poly-B pipes and calling Thunderbird Plumbing for your pipe inspection. Look underneath your sink and around your water heater to confirm the pipes are made from polybutylene. The following elements indicate the presence of Poly-B pipes:

  • Grey, black, or blue plumbing pipes
  • Pipes with plastic fittings
  • Stamps with “PB” such as “PB2110”  or “CSA-B”
  • Poly-b pipes are sometimes curved, unlike rigid copper pipes

The Dangers Associated with Poly-B Pipes

  • Poly-B pipes have a high failure rate because they were not built to withstand high heat and high water pressure and become brittle over time.
  • Exposure to elements such as chlorine can cause Poly-B pipes to crack and flake, leading to material degradation.
  • The degrading polybutylene allows fractures in the pipe, which increase in size over time, allowing water to leak into your home eventually causing burst pipes and catastrophic flooding.
  • As a result of investigations into Poly-B, insurance companies may no longer insure Poly-B pipes and may not cover claims associated with Poly-B pipe failure.
