Backflow Prevention

Backflow prevention devices are designed to prevent contamination or pollution from infiltrating water supplies. These devices are required by law in many municipalities, and must be properly installed and maintained in accordance with plumbing and building codes. Backflow prevention systems are required to be inspected once a year following installation. M & T is fully certified by the Ontario Water Works Association (OWWA) to install and inspect backflow prevention devices in the City of Toronto, Markham, and Halton Regions amongst others. We perform installations and inspections for industrial, commercial, institutional, and multi-residential properties.
