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.

Why is backflow testing mandatory in North Charleston?

SCDES mandates an active Cross-Connection Control Program for all water systems under R.61.58.7(F). That is why backflow devices are monitored and tested regularly. North Charleston also has an active local pool of backflow inspectors and testers listed by the state.

What to do next

  1. Ask the pro to verify the leaking device against the state's approved backflow prevention assemblies list before any replacement.
  2. Ask to see the tester's SC certification card and check it is within its 3-year validity period.
  3. Ask for proof of licence and insurance in the quote.
  4. Ask which test - double check valve assembly, pressure vacuum breaker, or reduced pressure principle assembly - applies to your device.
  5. Call (843) 286-4721 or email [email protected] for a free quote from a licensed, insured local backflow tester.
