A backflow prevention assembly is a valve that stops water from flowing backward out of your property into the public drinking water supply. Without one, a pressure drop in the city main could pull water from a lawn sprinkler system, which may carry fertilizer, pesticides or animal waste, back into the lines that feed your neighbors’ taps.
Utah’s drinking water rules require testable backflow assemblies to be tested by a certified tester when they’re installed and at least once a year after that. In St. George, Hurricane and the rest of Washington County, they’re most common on irrigation systems, and also on fire sprinklers, boilers and some commercial equipment. A test checks that each check valve and relief valve opens and closes as it should; a failed assembly needs repair or replacement before it’s retested.
Backflow testing is offered by our St. George & Hurricane team. It isn’t offered in Flagstaff, Durango or Jackson. If a test shows a failed assembly, every location offers plumbing repair: Flagstaff, Durango, St. George & Hurricane and Jackson.
