Poly-B Replacement in Delta, BC

Polybutylene plumbing was commonly installed in Delta 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 →

Delta is a 1960s-and-1970s city first: 17,735 of its 38,055 occupied dwellings, nearly half, were built between 1961 and 1980. The poly-B decades came next, with 6,270 dwellings from the 1980s and 4,375 from the 1990s, or 28.0% of the total in the 2021 Census. Construction has been slower since 2000, so the houses most likely to contain poly-B are those finished from about 1978 onward, along with older homes whose plumbing was renovated during those years.

British Columbia does not list plumbing among its seven compulsory certified trades (SkilledTradesBC), so ask who will do the work and what trade papers they hold. BC Housing’s leak guide suggests a pressure-reducing valve where pressure exceeds 80 psi and puts basic leak sensors at $10 to $150 (BC Housing). The Vancouver guide compares Delta with the rest of the region.
