What this means in Ainslie Wood North
Ainslie Wood North sits on the edge of the Poly B window, which makes it a neighbourhood of exceptions. Streets built a few years apart can differ completely: one phase plumbed in copper or early PEX, the next in Poly B. The build year of your specific home matters more here than the neighbourhood average, and a five-minute look at the pipe settles what no map can.
How to check a Ainslie Wood North 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 Hamilton replacement ranges. Selling or buying here? The disclosure chapter covers the rules that apply.
