Mount Pleasant, SC: what's different here
Mount Pleasant is located approximately 9 miles from Charleston, a drive that takes about 17 minutes via US-17. Local certified testers are available in Mount Pleasant, as confirmed by the South Carolina DES. The area requires adherence to state-level backflow prevention standards for all installations. Compliance with these rules is necessary for local water system requirements.
What is required for backflow testing in Mount Pleasant?
South Carolina rules require that each backflow prevention assembly be tested after installation and before use. Furthermore, local regulations require that each assembly be tested at least once annually by a certified tester. The Charleston Water System requires all reports to be filed through its third-party reporting process.
Who is qualified to perform the backflow testing?
A certified tester must hold a current certification card issued by the South Carolina Department of Environmental Quality. The state recognizes four types of certified testers: General Tester, Limited Tester, Inspector Tester, and Manufacturer’s Agent. These professionals must pass both a written and a proctored practical exam.
What are the technical standards for testing?
South Carolina DES requires that the tester’s differential gauge be accurate to within 2% of full gauge scale or +/- 0.3 psi differential. This standard ensures the integrity of the backflow prevention assembly during inspection. Local certified testers in Mount Pleasant are available to meet these specific requirements.
How long is the certification process for testers?
Initial certification training involves a four-day course, such as those offered at Midlands Technical College. Certification is valid for three years and must be renewed every three years to remain valid. Testers must also pass a proctored practical exam to earn their credentials.
