Summerville, SC: what's different here
Summerville is located in Dorchester County, South Carolina. It features a humid subtropical climate with an average annual precipitation of 52.7 inches. The town is approximately 25 miles and 30 minutes from Charleston via I-26. This location is subject to Charleston-area backflow concerns due to heavy rainfall.
SC Regulations for Backflow Preventer Leak Repair
South Carolina regulations require a backflow assembly to be tested immediately after any repair is made. Repairs must be conducted by a DES-certified backflow prevention assembly tester. This ensures compliance with state cross connection control laws.
Who is Qualified for Backflow Preventer Leak Repair in Summerville?
A certified tester must hold an up-to-date certification card issued by the Department. South Carolina recognizes four types of certified testers: General, Limited, Inspector, and Manufacturer's Agent. All testing must be performed by a state-certified backflow prevention tester.
Annual Testing Requirements for Backflow Assemblies
Backflow assemblies in South Carolina must be tested at least once annually by a certified tester. Heavy rainfall in the Charleston area is a known backflow concern because heavy rain can increase pressure on plumbing and drainage systems.
Certification Standards for Backflow Testing
Renewals for backflow prevention certification require a written exam with a passing score of 70%. Performance testing must also be completed on reduced pressure principal, double check valve, and pressure vacuum breaker assemblies.
What to do next
- Verify the local pro has a current backflow prevention assembly tester certification card from the SC DES.
- Ensure the repair is followed by a full assembly test, as required by SC regulations.
