Mount Pleasant, SC: what's different here

Mount Pleasant is located in Charleston County, South Carolina. It is approximately 9 miles and 15 minutes from Charleston via US-17. The area must adhere to specific cross-connection control policies. These regulations ensure that all backflow testing is performed by a state-certified backflow prevention tester.

Mount Pleasant Requirements for Sprinkler System Backflow Certification

Mount Pleasant Waterworks requires that all backflow assemblies be selected from SCDHEC’s approved-device list. A device must be tested by an SCDHEC-certified tester once it has been installed. This ensures compliance with local cross-connection control programs.

Annual Testing for Sprinkler System Backflow Certification in Mount Pleasant

A Charleston-area municipal policy states that residential irrigation backflow devices are tested upon installation and every 12 months thereafter. Mount Pleasant Waterworks confirms this annual testing requirement. Customers have 15 days after activation to test the assembly.

The SC DES Certification Process for Testers

South Carolina DES requires a 4-day course for backflow tester certification. This process includes both written and hands-on exams at the end. Certification is valid for three years, requiring renewal through a written exam and performance testing.

What to do next

  1. Verify if your device is on the SCDHEC approved-device list.
  2. Ensure the tester holds a current certification card issued by the SC DES.
  3. Confirm the testing is performed by a licensed, insured local backflow tester.
