A Poly B burst or active leak is a genuine emergency. Water damage in BC homes escalates fast — soaked insulation, saturated drywall, and mould growth can all begin within hours. When Poly B fails, the priority is stopping the water first, then planning a permanent fix. We respond to urgent Poly B failures across Coquitlam, Port Coquitlam, Port Moody, and the surrounding Tri-Cities area.
Why Poly B Failures Are Sudden
Poly B doesn't give visible warning before it fails. The degradation process happens inside the pipe wall — microscopic cracks from chlorine oxidation grow over years until the structural integrity of the pipe is compromised. At that point, normal operating water pressure (anywhere from 40–80 psi in a typical BC home) is enough to cause a complete rupture.
The failure is often at an elbow, a fitting, or a long straight run that has experienced repeated pressure cycling. In some cases it happens at a location that was fine the last time you looked at it. Poly B in BC homes built 30+ years ago is past its expected service life. An emergency is not a matter of if — it's a matter of when.
- No visible warning before sudden failure
- Fittings and elbows are highest-risk failure points
- Any Poly B over 25 years old is past expected service life
- Chlorinated water accelerates failure — BC municipal systems use chlorine
- Cold snaps stress already-degraded pipe to failure
What to Do If Your Poly B Is Leaking Right Now
If you have an active leak: shut off the main water supply immediately. The shutoff is typically at the water meter — in many Coquitlam homes it's in the mechanical room or crawl space. Then call us. Do not attempt to patch Poly B with plumber's tape or compression fittings as a permanent fix — these are temporary stops at best and can fail again quickly.
We'll stop the water, replace the failed section, and assess the surrounding pipe. A burst at one point is often a sign that adjacent sections are at a similar stage of degradation. We'll tell you exactly what we see and give you options — an emergency patch of the failed section, or a scope for full replacement. You decide.

Questions About This Service
Can you fix just the burst section and not replace everything?
Yes — an emergency patch of the failed section is an option. We'll be transparent with you about the condition of the surrounding pipe so you can make an informed decision about next steps.
Will my insurance cover a Poly B burst?
That depends on your policy. Many BC insurers cover sudden water damage from a Poly B failure — but are increasingly adding exclusions for homes with known Poly B that wasn't replaced. Review your policy and contact your broker. We can provide photos and documentation of the failure for your claim.
