Backflow Testing That Helps Protect Our Drinking Water

Backflow occurs when water flows in the wrong direction, potentially carrying chemicals, contaminants or other unwanted substances into the drinking water supply. Pressure changes caused by water main breaks, firefighting or connected equipment can create these conditions. A properly functioning backflow preventer helps protect both your property’s water supply and the wider community.

Regular testing checks that your backflow prevention assembly is working as intended—something a visual inspection alone cannot confirm. The American Water Works Association (AWWA) supports ongoing testing and maintenance as part of effective backflow prevention. Locally, the City of St. Thomas requires annual testing through its backflow prevention program under By-law 44-2000, with completed test results submitted to the City.

We explain the results, provide testing documentation and recommend repairs or replacement when needed. Whether you’re arranging your annual test or addressing a failed device, we’re totally here for you.
