How to Tell If Your Edmonton Home Still Has Poly B Plumbing (And What to Do Next)

September 12, 2025

Numerous homes constructed in Edmonton from the 1970s through the 1990s may still contain Poly B (polybutylene) plumbing concealed within their walls. Although they may not pose immediate issues, these pipes are notorious for failing without warning, frequently resulting in leaks, insurance complications, and costly repairs. The difficulty for many homeowners lies in determining whether Poly B is present in their property—and understanding the appropriate actions to take if it is.



What is Poly B Plumbing?


Poly B, short for polyethylene, refers to a type of grey plastic pipe that saw widespread use in Canadian homes until the late 1990s. Its early popularity was due to its cost-effectiveness and ease of installation in comparison to traditional copper pipes. However, as time went on, the shortcomings and weaknesses of Poly B became more apparent, especially in Edmonton’s harsh climate, the chlorine found in municipal water, and its general degradation, prompting many homeowners to explore alternative options.


How to Identify Poly B in Your Edmonton Home


If you’re unsure whether your home features Poly B pipes, there are several distinctive traits you can look for to help identify them:


1. Pipe Colour: The most prevalent Poly B pipes are light grey, although they can also appear in blue, silver, or even black hues.


2. Stamping: Check for the identification code “PB2110,” which is usually printed on the pipe's surface.


3. Locations: Typical areas to examine include around your hot water tank, beneath sinks, in basements, or even behind washing machines, as these spots commonly housed Poly B pipes.


4. Fittings: Poly B pipes often connect with various metal or plastic fittings, which may exhibit visible signs of wear, leaks, or corrosion over time.

Risks of Poly B Plumbing in Edmonton


There are several noteworthy risks associated with having Poly B plumbing in your home, especially in a city like Edmonton:


- Leaks and Flooding: Even a minor pinhole leak can quickly escalate, resulting in significant water damage that can be costly to repair.


- Insurance Issues: Many insurance companies in Alberta are reluctant to provide coverage for homes with Poly B plumbing, or they may charge higher premiums due to the associated risks.


- Resale Value: If you plan to sell your home in the future, the presence of Poly B plumbing may raise concerns among potential buyers, which could lead to a decrease in your home’s resale value.


- Cold Weather Stress: Edmonton’s freeze-thaw cycles can impose additional stress on these already susceptible pipes, heightening the likelihood of complications.


What To Do If You Discover Poly B


Schedule a Professional Inspection – It’s crucial to consult a qualified plumber who can accurately determine the extent of Poly B plumbing in your residence. This expert evaluation will give you a comprehensive insight into the current state of your plumbing system.
