Regular backflow preventer maintenance isn't just good practice - it's often required by local water authorities. This Ladson assembly showed significant corrosion on the exterior brass components, though the internal check valves were still functioning. We serviced the unit by testing the check valves, cleaning the exterior, and verifying proper operation at the required pressure differentials. Annual testing catches problems early and keeps your water supply protected year-round. Schedule your backflow testing today to stay compliant and keep your drinking water safe.
