Why Backflow Prevention Is Required in Mississauga
Backflow prevention in Mississauga is regulated by the Region of Peel to protect the municipal drinking water system. Under By-law 10-2017, properties classified as moderate or high hazard must install approved backflow preventers and complete certified backflow testing annually.
Backflow can occur due to:
Water main breaks
Fire hydrant usage
Sudden drops in water pressure
Pump failures
Improper cross connections
Without proper plumbing backflow protection, contaminated water can flow back into the public water supply.
Property owners in Mississauga are legally responsible for maintaining backflow compliance, including installation, annual backflow testing, repair of failed devices, and submission of documentation.
