Common issues include worn-out check valves, faulty relief valves, or damaged springs. Our team carries a wide range of replacement parts for leading brands like Watts, Wilkins, Febco, and Conbraco.

Freeze and Heat Protection for Backflow Preventers in La Crosse, WI
Above-ground backflow assemblies are exposed to summer sun and winter cold. Insulating pipes on exterior walls, shutting off outdoor faucets and keeping garages warm prevent most freeze damage. Freezing can crack bodies and bonnets, while UV exposure breaks down plastic parts. We install insulated pouches, heated enclosures or lockable cages as needed. Protecting the assembly helps it pass testing and last longer.

We test all common types, including RPZs, DCVAs, and PVBs, with accurate readings and proper operation.
Backflow Repair vs. Replacement Cost in La Crosse, WI
