What should Markham buyers know about Kitec and Poly-B plumbing?Kitec, a flexible pipe with brass fittings often in blue and orange, was installed in some Canadian homes and condos from the mid-1990s into the 2000s, and its fittings can deteriorate and leak. Poly-B is an older grey plastic pipe. Insurers often ask about both and may add restrictions. Have a plumber confirm the material, disclose it to your insurer, and get itemized replacement quotes before you firm up.
Many Markham homes from the 1990s and early 2000s, and some condos, were built during the years these products were used.
Michael John Lau, a REALTOR® with the Kaizen Real Estate Team, one of the most active real estate teams in Markham and York Region, asks about plumbing materials early, because insurance can depend on the answer.
How to spot them
| Material | Look for |
|---|---|
| Kitec | Blue and orange pipe, brass fittings, stamps such as Kitec, KTC, PlumbBetter or WarmRite, sometimes a sticker near the panel |
| Poly-B | Grey plastic pipe, often with plastic or metal crimp fittings |
Check near the water heater, under sinks and in the mechanical room, without cutting into walls. A plumber should confirm.
Why insurers care
Failed fittings can cause water damage. Sudden water damage may be covered, but insurers commonly do not pay to replace the pipe itself, and some add restrictions, exclusions or deadlines for replacement. Ask for the insurer’s requirements in writing.
Replacement
- Get at least two itemized quotes covering the same scope.
- Include drywall repair, permits and fire stopping.
- Keep the plumber’s report and photos as proof of the repipe.
- The Kitec class action claims deadline passed in January 2020.
