West Ashley, SC: what's different here
West Ashley sits in Charleston County, South Carolina, and is served by Charleston County government and utility programs. The area is about 10 miles and roughly 17 minutes by car from downtown Charleston via US-17 S. Charleston's hot, humid summers with afternoon thunderstorms from June through September can affect exterior testing and scheduling. Sandy, low-lying soils and a high water table can also affect underground utility work.
Who must perform the backflow test in West Ashley?
In South Carolina, all backflow testing must be done by a state-certified backflow prevention tester. The state defines a certified tester as a person holding an up-to-date backflow prevention assembly tester certification card issued by the Department. Installations must be completed by a licensed plumber.
How often does a West Ashley backflow test need to be done?
One Charleston-area utility program says all assemblies must be tested upon installation and annually thereafter. Annual testing must be completed by a SCDES-certified backflow tester. Charleston-area testing can be billed annually.
How long is a tester's certification valid?
A certified tester's credential is valid for 3 years in South Carolina. Recertification through GSWSA is a 3-day workshop that costs $250.00 per person. Ask the pro for their current certification card before booking.
