West Ashley, SC: what's different here
West Ashley is a Charleston neighborhood in Charleston County, South Carolina, about 10 miles and roughly 17 minutes by car from downtown Charleston via US-17 S. Homes and businesses there fall under South Carolina's cross connection control rules, which require annual certified testing of backflow assemblies. Local testers also serve the broader Charleston area, so scheduling is straightforward from West Ashley.
How often is backflow preventer testing required in West Ashley?
South Carolina rules require testing after installation and before use, then at least once annually. That means most West Ashley properties need a certified test every year. Ask the pro to schedule so you stay on the annual cycle.
Who can perform backflow testing in West Ashley, SC?
Only a state certified backflow prevention tester can do the test. The tester must hold a current Tester Certification Certificate from a DES-approved training seminar. Ask the pro for proof of licence and insurance before they start.
