What is Poly-B Plumbing? (Polybutylene Explained)
If you own a home in Chilliwack, Abbotsford, Mission, or the Fraser Valley, you may have heard about Poly-B plumbing.
Poly-B (Polybutylene) is a grey plastic water piping system commonly installed in homes from the late 1970s to mid-1990s.
It’s often found in mechanical rooms, under sinks, and behind walls, and may be marked “PB” or “PB2110”.
Why is Poly-B a concern?
Over time, Poly-B can deteriorate due to normal water conditions. The pipe can become brittle and fail without warning—often from the inside out.
Homeowners may experience:
• Hidden leaks
• Cracked fittings
• Sudden pipe failures
Should it be replaced?
Many homeowners are choosing to replace Poly-B plumbing proactively to help prevent water damage, meet insurance requirements, and improve long-term reliability.
