West Ashley, SC: what's different here
West Ashley is a Charleston County area, identified in Census data as the West Ashley CCD. It sits about 10 miles and roughly 17 minutes by car from Charleston via US Route 17. As a coastal community subject to storm surge and heavy rain, Charleston County identifies backflow valves as a flood-damage prevention measure. The county recommends a qualified, licensed plumber install an interior or exterior backflow valve, with permit requirements checked through Building Services.
Who can perform sprinkler system backflow certification in West Ashley?
South Carolina requires all backflow testing to be done by a state certified backflow prevention tester. A certified tester is defined as a person holding an up-to-date backflow prevention assembly tester certification card issued by the Department. Ask the pro for proof of certification before the test.
How often is sprinkler system backflow certification required?
Certification is a recurring compliance requirement, not a one-time task. A certified backflow prevention tester's license in South Carolina expires every 3 years, and recertification means retaking the three-day workshop. Irrigation customers in one South Carolina utility service area must test each assembly upon installation and annually thereafter.

One training provider lists the course at 28 class hours and $699.00, not including fees and equipment.
Where can tester certification classes be taken near West Ashley?
