Backflow preventers keep water in your building from flowing back into the public supply. In Durham Region, By-law 24-2018 requires them on industrial, commercial, institutional and multi-residential properties classified as severe or moderate hazards, tested every year.
Backflow is the undesirable reversal of water flow in a plumbing system, which can contaminate drinking water. A backflow prevention assembly keeps water in your own system from flowing back to the public water system. The Region of Durham's Backflow Prevention By-law 24-2018 applies to industrial, commercial, institutional and multi-residential properties classified as severe or moderate hazards, and their devices need testing and maintenance every year. Hayes Plumbing provides testing, installation, repair and emergency service across Durham Region.
