How can I tell if my Edmonton home has Poly B?
The straight answer
Check the year first: Edmonton homes built or replumbed 1978 to 1998 are the candidates, roughly 23 percent of the city’s housing stock. Then look for the pipe: grey, flexible, stamped PB2110, at the water heater, under sinks, or along basement joists.
The longer version
Same two-step check as anywhere in Alberta. The era: 1978 to 1998 is the install window, and about 23 percent of Edmonton’s housing stock dates to it. Run your address through the checker or find your area in the Edmonton neighbourhood profiles, 206 of them, most with a clear build-era verdict. Then the pipe: grey and flexible with PB2110 printed along its length, checked in two minutes at the water heater, under the kitchen sink, and along the basement ceiling. The identification guide walks every spot with photos.
