If you own a home in Calgary built between the late 1970s and mid-1990s, there’s a good chance your plumbing system includes Poly B piping. While it was once a popular choice for residential plumbing, Poly B has since proven to be problematic, posing risks to your property, insurance coverage, and peace of mind. 
In this guide, we’ll walk you through everything you need to know about Poly B plumbing, how to identify it, and why Aquality Plumbing & Heating is Calgary’s trusted expert for safe, professional replacement.
What Is Poly B Plumbing?
Polybutylene (Poly B) is a flexible, grey plastic pipe that was widely used in residential plumbing systems across North America from the late 1970s until the mid-1990s. It was inexpensive, easy to install, and initially considered a breakthrough in plumbing technology.
However, over time, Poly B began to show serious flaws:
- It deteriorates when exposed to oxidants, such as chlorine, which is commonly found in municipal water supplies.
- It’s prone to cracking and leaking, especially at joints and fittings.
- It’s no longer accepted by building codes in many regions, including Calgary.
Why Poly B Plumbing Is a Risk
Poly B pipes may look harmless, but they carry significant risks for homeowners:
- Leaks and Water Damage: Poly B pipes are notorious for sudden leaks, which can cause extensive damage to drywall, flooring, and personal belongings. These leaks often occur without warning and can be costly to repair.
- Insurance Limitations: Many insurance providers in Calgary either refuse coverage for homes with polybutylene (Poly B) plumbing or impose higher premiums. Some may even require full replacement before issuing a policy.
- Health Concerns: While Poly B itself isn’t considered toxic, leaks can lead to mold growth, which poses health risks—especially for children, seniors, and those with respiratory conditions.
- Reduced Property Value: Homes with Poly B plumbing may face lower resale values or longer time on the market due to buyer concerns and inspection issues.
How to Identify Poly B Plumbing in Your Home
Does your home have polybutylene (Poly B) pipes? Here’s how to check:
- Look for grey plastic pipes—usually flexible and about ½ to 1 inch in diameter.
- Check near your water heater, under sinks, or in the basement ceiling.
- Look for markings like “PB2110” printed on the pipe.
- Review your home’s construction date—if it was built or renovated between 1978 and 1995, polybutylene (Poly B) is likely to be present.
If you’re unsure, Aquality Plumbing & Heating offers inspections to confirm the presence of Poly B and recommend next steps.
