Who is a Qualified Backflow Tester?
South Carolina DES mandates that all backflow testing must be done by a state-certified backflow prevention tester. There are four recognized types of certified testers: General Tester, Limited Tester, Inspector Tester, and Manufacturer’s Agent. A certified tester holds an up-to-date certification card issued by the Department.
The Process for Backflow Certification
Becoming qualified to perform backflow certification is not a same-day process. Charleston training classes are listed as a 4-day course. To earn certification, a tester must pass a written exam with a score of 70% and perform hands-on tests on specific assemblies.
When to Call a Pro for annual backflow certification in Charleston
You must call a local pro if you are not a state-certified backflow prevention tester. South Carolina regulations require annual testing except for limited exceptions. If you are unsure if your current certification is up to date, contact a local pro to verify compliance.
