What Is Poly-B Piping?

Poly-B (short for polybutylene) is a flexible plastic pipe that was widely used for water supply lines in homes across Canada from 1978 to 1998. It was marketed as an affordable and easy-to-install alternative to copper piping, making it very popular among builders.

Poly-B pipes are usually:

• Grey in color (sometimes blue or black)

• Flexible, with plastic or metal fittings

• Found behind walls, in basements, or under floors

Why Was Poly-B Piping So Popular?

When Poly-B was introduced, it seemed like the perfect solution—cheaper than copper, resistant to corrosion, and easy to install. For nearly two decades, it was the go-to choice for many plumbing systems in Langley homes.

The Problem With Poly-B Piping

While it seemed like a great idea at first, Poly-B piping has significant long-term issues, including:

• Cracking and Leaking: Over time, Poly-B pipes become brittle, leading to cracks and leaks.

• Fittings Fail: The plastic fittings often fail, causing sudden water damage.

• Chlorine Sensitivity: Poly-B pipes deteriorate when exposed to chlorine in water supply lines.

• Insurance Concerns: Many home insurance companies refuse coverage or increase premiums if Poly-B is present.

How Do You Know If You Have Poly-B Pipes?

Here’s how to check:

• Look for grey-colored pipes near your water heater, under sinks, or in your basement.

• Check for a “PB” or “Poly-B” stamp on the pipe.

If you’re unsure, call Langley Home Plumbing for a professional inspection.

Should You Replace Poly-B Piping?

Yes. Most plumbing experts recommend replacing Poly-B pipes with PEX or copper as soon as possible. The cost of proactive replacement is far less than the damage from a burst pipe.

Delaying replacement can lead to:

• Major water damage in your home

• Mold growth

• Higher insurance premiums or denied coverage
