Replacing Poly B (Polybutylene) Pipes in Winnipeg Homes

Poly B (Polybutylene) Pipes

Poly B, also known as polybutylene plumbing, was a popular choice for residential water lines from the late 1970s to the mid-1990s. These grey plastic pipes were inexpensive and easy to install, but time has shown that Poly B piping is prone to leaks, bursts, and costly water damage. If your home still has polybutylene (Poly B) pipes, it’s strongly recommended that you consider repiping.

Below are the most frequently asked questions by Winnipeg homeowners about Poly B replacement.

What is Poly B (polybutylene) piping?

Poly B, short for polybutylene, is a flexible, grey plastic plumbing pipe that was widely installed in Canadian homes between 1978 and 1995. It was used for both hot and cold water supply lines.

Over time, Poly B has proven to be unreliable because it can deteriorate, crack, or burst under pressure, especially when exposed to high chlorine levels in city water.

Why should I replace Poly B pipes?

Poly B pipes have a high risk of failure. Common problems include:

• Leaks and bursts leading to water damage.

• Insurance issues – many providers either increase premiums or refuse coverage for homes with Poly B.

• Reduced resale value – buyers are wary of homes with outdated plumbing.

Replacing Poly B improves your home’s safety, protects against water damage, and increases property value.

How do I know if I have Poly B pipes?

Look for:

• Grey plastic pipes often marked with “PB2110.”

• Typically installed near water heaters, under sinks, or in unfinished basements.

If you’re unsure, a licensed plumber can perform a plumbing inspection and confirm if your system has Poly B.

Can I still live with Poly B pipes?

While Poly B may still carry water, it’s not a long-term solution. Most failures occur without warning, and leaks often appear in hidden areas, such as behind walls. Continuing to rely on Poly B increases your risk of sudden plumbing emergencies.

How much does it cost to replace Poly B piping in Winnipeg?

The cost depends on the size of your home, number of bathrooms, and type of replacement material (commonly PEX or copper). On average, repiping a home in Winnipeg ranges from several thousand dollars to over ten thousand.

The best way to get an accurate cost is to request a professional in-home estimate.

What materials replace Poly B?

The most common and reliable replacement options are:

• PEX piping – flexible, durable, and resistant to freezing.

• Copper piping – long-lasting and corrosion-resistant.

Both are approved under Canadian building codes and provide decades of reliable service.

Will insurance cover Poly B replacement?

Typically, insurance does not cover replacement of Poly B pipes, since it’s considered an upgrade rather than a repair. However, replacing them may lower your premiums and make it easier to get coverage.

How long does it take to repipe a house?

Most Winnipeg homes can be fully repiped in 3–7 days, depending on size and complexity. A skilled plumbing team will minimize disruption and restore water service as quickly as possible.
