Poly B in Calgary, neighbourhood by neighbourhood

Calgary boomed through exactly the wrong years for plumbing. The city added enormous suburban tracts through the 1980s and 1990s, and Alberta alone is estimated by the province to hold roughly 148,000 homes with Poly B. The upside for Calgary owners: Canadian installs here typically used copper or brass insert fittings, which carry a better record than the plastic fittings common in the US.
