Does Westwood, Edmonton have Poly B plumbing?
Lower likelihood
The 30-second answer
Lower likelihood from original construction. Westwood was largely built around 1960, before the Poly B era. Census data for the area around Westwood counts 245 occupied homes, with roughly 12% dating to the 1978 to 1998 Poly B installation window. Only a look at the pipe confirms anything about a specific home.
When Westwood was built
Statistics Canada’s 2021 Census records the construction period of every occupied home. Here is the distribution for the census area at the heart of Westwood, with the periods overlapping the Poly B era in red:
Occupied private dwellings by period of construction, 2021 Census. The 1961 to 1980 bucket only partially overlaps the Poly B era, which our scoring weights accordingly.
What this means in Westwood
Westwood's construction era falls mostly outside the Poly B window, so original plumbing here is typically copper, galvanized, or modern PEX depending on age. The caveat that matters: homes renovated, converted, or replumbed between 1978 and 1998 can still carry Poly B regardless of when they were first built, and basement developments from that era are a classic hiding spot.
How to check a Westwood home
Look where pipe is visible: the ceiling of an unfinished basement area, under sinks, at the hot water tank, and at the main shut-off. Poly B is usually grey and flexible and reads PB2110 on the pipe wall. The identification guide has photos and a room-by-room walkthrough, and the address checker gives a street-level read for any address. Don’t forget the buried water service line, which can be polybutylene even when the house isn’t.
If you find it
Don’t panic, and don’t ignore it either. Poly B fails from the inside as chlorinated water embrittles the pipe, so its condition can’t be judged by looking at it. The failure chapter explains the mechanism, the insurance chapter covers what it means at renewal time, and the cost guide gives honest Edmonton replacement ranges. Selling or buying here? The disclosure chapter covers the rules that apply.
