Why Loudoun County Requires Backflow Testing
Loudoun Water requires annual testing of all backflow prevention assemblies to ensure safe drinking water throughout the county. Irrigation systems are considered a potential cross-connection because fertilizers, soil, and contaminants can enter the water supply if backflow occurs.
To prevent this, every approved backflow device must be tested yearly by a certified backflow tester and reported to Loudoun Water.
