As Calgary homeowners, we often overlook what’s behind our walls – until there’s a problem. One such hidden danger lurking in many Calgary homes built between 1985 and 1997 is Poly B piping. At Harper’s Plumbing, we’ve seen firsthand the devastating effects of Poly B failures, and we’re here to shed light on this critical issue.
What is Poly B plumbing?
Poly B, short for Polybutylene, was widely used in residential plumbing systems from the mid-1980s to the late 1990s. Initially celebrated as a cost-effective alternative to copper, it has since shown significant drawbacks:
- Chlorine Sensitivity: Poly B can degrade when exposed to chlorine over time.
- Cracks and Leaks: It has a tendency to develop microscopic cracks that can lead to major issues.
- Unexpected Failures: These pipes can burst with little warning, causing extensive damage.
Poly B pipes were marketed as “the pipe of the future” due to their low cost, flexibility, and ease of installation. However, this promise quickly turned into a nightmare for many homeowners.
When was Poly B banned in Canada?
Poly B’s reputation began to crumble in the mid-1980s when insurance companies noticed a pattern of leaks emerging in homes with polybutylene piping. By 1995, most tradespeople had stopped using the material in residential construction. The situation became so severe that in 1997, Poly B was banned by the National Plumbing Code, which oversees plumbing trades in Canada.
The final nail in the coffin came in 2005 when the NRC-CNRC National Plumbing Code and the Government of Canada officially removed Poly B from the list of acceptable plumbing piping materials. As a result, typically only homes built between 1978 and 1995 have polybutylene piping installed.
This rapid fall from grace was due to several factors:
- Frequent leaks and pipe failures
- Susceptibility to damage from chlorine in water systems
- Degradation when exposed to high temperatures
The issue became so widespread that a $1 billion class action lawsuit was settled in the USA, covering the cost of replacing Poly B systems in 320,000 homes. This legal action underscores the severity of the problems associated with Poly B piping and the significant financial impact on homeowners and the construction industry.
The Risks of Waiting
Many homeowners are unaware they have Poly B until it’s too late. A single pipe failure can lead to:
- Water Damage: Resulting in costly repairs and significant disruption.
- Mold Growth: Even small leaks can create conditions for mold to thrive behind walls.
- Structural Issues: Over time, leaks can compromise your home’s integrity.
Insurance and Resale Challenges
Square One Insurance highlights several challenges associated with homes that have Poly B piping:
- Insurance Difficulties: Many insurers now require replacement of Poly B in Calgary or charge higher premiums for homes with this piping. Some may even deny coverage altogether.
- Resale Issues: Homes with Poly B are becoming harder to sell or may sell at a discount. Square One advises that it’s crucial to know what type of plumbing is in your home before buying or seeking insurance.
- High Deductibles: Claims related to Poly B might face high deductibles, leaving homeowners with substantial out-of-pocket expenses.
Why 2024 is the Year to Act
- Age Factor: Most Poly B installations in Calgary are now 25-35 years old – well beyond their expected lifespan.
- Increasing Risk of Leaks: Square One reports that “Poly-B piping begins to leak around 10 to 15 years after installation,” meaning any existing Poly B is likely already at risk.
- Protect Your Investment: Replacing Poly B now may help safeguard your home’s value and insurability.
