Mount Pleasant, SC: what's different here
Mount Pleasant is in Charleston County, South Carolina, about 9 miles and roughly 17 minutes by car from Charleston via US-17. The area has a humid subtropical climate with hot, humid summers and mild winters, averaging around 50 inches of rain a year. Its coastal location brings saltwater exposure and moisture, which can stress plumbing and backflow devices.
Who is allowed to test backflow devices in South Carolina?
South Carolina requires all backflow testing to be done by a state-certified backflow prevention tester. The state offers four tester types: General Tester, Limited Tester, Inspector Tester, and Manufacturer's Agent. Ask the pro for proof of licence and insurance before work starts.
How often does a backflow device need testing?
Each backflow prevention assembly must be tested after installation and before use. After that, it must be tested at least once a year by a certified tester. Mount Pleasant Waterworks also runs its own annual backflow program.
What does Mount Pleasant Waterworks charge for backflow?
Mount Pleasant Waterworks charges an annual program fee of $50 per device, billed to your water and wastewater bill. If testing is not completed, the utility states water service can be disconnected and a $65 fee added to the bill.
What happens after a new backflow device is installed?
After installation, the device must be tested by a SCDHEC-certified tester. The test report must be returned to Mount Pleasant Waterworks within 30 days. Inspections of new installations can be requested and are conducted within 72 hours of the request.
