Harleston Village: what's different here
Harleston Village is one of Charleston’s oldest downtown neighborhoods. It features historic single houses and Victorian homes, some dating back to the 1700s. The area is highly walkable, situated on the downtown peninsula between Calhoun and Broad Streets. Colonial Lake sits at the center of this historic neighborhood.
SC DES Backflow Testing Requirements
South Carolina’s Department of Environmental Services requires an active cross-connection control program for all water systems. Backflow prevention assemblies must be tested annually to ensure they function properly. All testing must be performed by a state-certified backflow prevention tester.
Harleston Village Backflow Testing Process
Standard backflow testing is usually quick, often taking between 20 to 45 minutes for a typical assembly. If a new backflow preventer installation is needed, the process can take several hours or even a full day depending on plumbing access.
Understanding Backflow Testing Costs
