West Ashley, SC: what's different here
West Ashley sits in Charleston County, South Carolina, about 10 miles and roughly 17 minutes from downtown Charleston via US Route 17. The area's housing stock includes a mix of ranch homes and newer construction. Its humid subtropical climate can affect home materials over time. Certified backflow testers serving the Charleston area are listed publicly by the state, so local service is available.
Who can perform a reduced pressure zone assembly test in West Ashley?
South Carolina requires all backflow testing to be done by a state-certified backflow prevention tester. A certified tester holds 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 an RPZ assembly tested in West Ashley?
South Carolina requires backflow prevention assemblies to be tested after installation and at least once annually after that. Plan on a yearly test for your reduced pressure zone assembly. Ask the pro about scheduling so you stay current.
What equipment does a certified tester use?
South Carolina requires the tester's differential gauge to be accurate to within 2% of full gauge scale or +/- 0.3 psi differential. This accuracy standard helps ensure valid test results. You can ask the pro what gauge they use.
How do I verify a tester's certification in South Carolina?
