Who needs backflow testing
- Commercial and industrial buildings connected to Region of Peel water
- Properties with fire sprinkler systems
- Buildings with irrigation systems or boilers
- Some multi-unit residential buildings
What testing involves
A certified tester uses a calibrated gauge to check that each check valve and relief valve in the device holds pressure correctly. Water is shut off briefly. If the device passes, a report is filed with the Region. If it fails, it is repaired and retested.
- Arrange a time when brief water shut-off is acceptable.
- Test each valve with a calibrated kit.
- Repair or rebuild if needed.
- File the test report as required.
Regional rules
The Region of Peel has a backflow prevention program with reporting rules for many properties. Requirements can change, so check the current Region rules for your building type. Most single-family houses do not need annual testing, though some features like irrigation may need a device.
