Polybutylene (poly-B) pipe leaks or failures
Common Causes
- Chlorine in municipal water reacts with polybutylene, causing micro-cracking from the inside out
- UV light exposure at exposed pipe sections accelerates degradation
- Pipe fittings (acetal plastic) fail at compression points
- Age — most poly-B is now 35-45 years old and past reliable service life

- Home insurance renewal is approaching — many insurers in Alberta no longer cover homes with poly-B
- You are buying or selling a home with poly-B — negotiate a replacement allowance
- Pipe is showing grey or beige plastic piping with "PB2110" stamped on it

Alberta Context
Approximately 17% of Innisfail's housing stock was built between 1981-1990, the peak era for polybutylene pipe installation. Poly-B was used in hundreds of thousands of Alberta homes during this period. In 2023-2024, several major Canadian insurers including Intact and Aviva began restricting coverage on homes with poly-B, increasing replacement urgency. The Town of Innisfail's municipal water is chlorinated, which is the primary driver of poly-B degradation. PEX-A (Uponor AquaPEX) is the preferred modern replacement material — flexible, freeze-resistant, and rated for 50+ years.
