Does City Centre, Coquitlam have Poly B plumbing?

Lower likelihood

The 30-second answer

Low likelihood. Homes in City Centre were mostly built 2011 to 2015, after Poly B production ended. Census data for the area around City Centre counts 2,970 occupied homes, with roughly 14% dating to the 1978 to 1998 Poly B installation window. Only a look at the pipe confirms anything about a specific home.

When City Centre 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 City Centre, with the periods overlapping the Poly B era in red:

1960 or before0
1961 to 198020
1981 to 1990100
1991 to 2000380
2001 to 2005180
2006 to 2010725
2011 to 20151,120
2016 to 2021440

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 City Centre

City Centre'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 City Centre 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 Coquitlam replacement ranges. Selling or buying here? The disclosure chapter covers the rules that apply.
