North Charleston, SC: what's different here
North Charleston is in Charleston County, South Carolina, about 6 miles and roughly 10 minutes by car from Charleston via the main highway. The state lists an active local pool of backflow inspectors and testers serving the North Charleston area. Water systems there fall under South Carolina's mandated Cross-Connection Control Program, so backflow devices are tested regularly.
Who is qualified for backflow preventer leak repair in North Charleston?
South Carolina requires all backflow testing to be done by a state-certified backflow prevention tester. A certified tester holds an up-to-date certification card issued by the Department. Ask the pro for proof of licence, certification and insurance before work starts.
Does my backflow device have to be on an approved list?
Yes. Any backflow prevention assembly used in South Carolina must be on the state's approved backflow prevention assemblies list. Check that list before agreeing to a replacement device for your leak.
How do I check a tester's certification in North Charleston?
South Carolina tester certification is valid for 3 years and must be renewed to remain valid. You can ask to see the tester's certification card issued by the Department. Certification is earned after a proctored practical exam and a written exam.
