Quick takeaways
- Poly B is grey plastic plumbing with metal or plastic crimp fittings.
- It was used in many Kanata homes 1985-1997.
- Failures (typically at fittings) are unpredictable and can be catastrophic.
- Some insurers now require replacement or charge significantly higher premiums.
How to identify Poly B in your home
Look in your basement, mechanical room, or under sinks. Poly B is grey plastic pipe (sometimes labelled 'PB2110'), typically 1/2 inch, with copper or grey plastic crimp fittings. It's not PEX (which is usually red, blue, or white). If you have a Bridlewood, Glen Cairn, or older Beaverbrook home built between 1985 and 1997, you probably have at least some Poly B.
Replacement options and cost
Full-house Poly B repipe in a typical Kanata 1,800-2,400 sq ft two-storey runs $7,500-14,000 depending on how much drywall opening is required. We typically go with PEX-A and try to route through accessible paths to minimize drywall work.
