Mount Pleasant, SC: what's different here
Mount Pleasant sits about 9 miles and roughly 15 minutes by car from Charleston via the main highway. Homes here are served by Mount Pleasant Waterworks, which runs an annual backflow testing program billed at $50 per year on the water and wastewater bill. Staying current with that annual test matters locally, because missed testing can lead to disconnection and a $65 fee. A local pro can handle the inspection and file the required report.
Who can perform a residential backflow inspection in Mount Pleasant?
South Carolina requires all backflow testing to be done by a state-certified backflow prevention tester certified by the Department of Environmental Services. Certification requires passing a proctored practical exam and a written exam, and it must be renewed every 3 years. Ask any pro for their current certification card before the test.
How often is a backflow test required in Mount Pleasant?
South Carolina Regulation R.61-58 requires each backflow assembly to be tested after installation and before use, then at least once annually by a certified tester unless an exception applies. Mount Pleasant Waterworks runs an annual testing program with a $50 annual fee charged to your water and wastewater bill. If required testing is not completed, water service can be disconnected and a $65 fee added to the bill.
What affects the price of a residential backflow inspection?
Charleston-area backflow testing is commonly priced at about $50 to $200 per device. The exact price depends on the device type and installation complexity. Ask the pro for a written quote covering the test, any report filing, and possible retest fees.
How does a tester become certified in South Carolina?

The state lists four types of certified testers: General Tester, Limited Tester, Inspector Tester, and Manufacturer's Agent.
