Poly-B in New Westminster homes

Polybutylene plumbing was commonly installed in New Westminster homes built between 1978 and 1998. If your home was constructed during this period, there's a possibility it contains poly-B pipes. Many insurance companies in British Columbia now have specific policies regarding polybutylene plumbing, including potential surcharges or requirements for replacement. Learn more about poly-B →

New Westminster mixes some of the region’s oldest housing with a solid block from the poly-B years. Nearly one dwelling in five (18.6%) predates 1961, while the 2021 Census counts 4,395 from 1981–1990 and 5,325 from 1991–2000, which is 9,720 homes or 26.9% of 36,095.

For apartment and townhouse owners, the key law is BC’s Strata Property Act: a pipe in a wall shared with another unit, or one that serves other units, belongs to the common property (BC Laws). The standard bylaws add that altering common property needs the strata corporation’s written approval, which may come with a condition that the owner pays (standard bylaws). BC Housing also advises owners to get that permission in writing before any professional alters the plumbing (BC Housing). The Vancouver guide covers costs and insurance across the region.
