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.
