Licensed Plumber in Markham — Trusted Local Plumbing Services

Markham covers a large area with housing from multiple eras. The preserved 1820s–1890s Unionville village heritage core contrasts with 1970s–1990s south Markham subdivisions in Milliken and Cornell, and the 2010s condo and commercial development around Markham Centre and Highway 7. York Region's mixed water supply (Lake Ontario and groundwater wells) creates variable hardness of 6–8 gpg depending on the area.

Markham's water chemistry interaction with Kitec brass fittings installed in homes built 1995–2007 is a significant concern. York Region's water causes dezincification of these fittings — the zinc component leaches out, leaving porous, weak brass that fails suddenly. Markham homeowners with Kitec pipe should have a professional assessment.
