A backflow preventer keeps water from an irrigation system or other connection from flowing back into the drinking water supply. About 73% of Fort Mill homes were built since 2000, so many original water heaters and irrigation backflow assemblies are reaching replacement age together. Testing is required periodically, and outdoor assemblies need protection from freezes.
Testing and repair: backflow testing in Fort Mill
How often is backflow testing required?
Utilities generally require testing when an assembly is installed and periodically after that, often annually; your water provider sets the schedule and the list of approved testers.
Can a failed assembly be repaired?
Often. Many assemblies can be rebuilt with replacement parts and retested rather than replaced.
Freeze protection: backflow testing in Fort Mill
Outdoor assemblies left full in winter can freeze and crack. Drain or insulate them in fall, and test when the irrigation system is turned back on in spring.
