Backflow preventers protect the public water supply from contamination and most utilities require annual testing by a certified tester. We test, certify, file the paperwork and repair or replace failed devices for homes, irrigation systems, fire sprinklers and commercial properties.
Homes in Washington range from older houses with original galvanized and cast iron plumbing to new construction with PEX — and each needs a different approach to backflow testing.
