James Island, SC: what's different here
James Island sits in Charleston County, about 6 miles and roughly 10 minutes from downtown Charleston via the James Island Connector. It is one of Charleston's lowest and flattest areas, with a maximum elevation of about 18 feet along Maybank Highway. The local Charleston soil series is deep, moderately well drained loamy soil, and the area averages about 65 degrees and roughly 48 inches of rain per year.
Who can perform irrigation backflow testing in James Island?
South Carolina requires all backflow testing to be done by a state certified backflow prevention tester. That means a person holding an up-to-date certification card issued by the Department of Environmental Services. Ask the pro for proof of licence and insurance before the test.
Why does James Island's irrigation system need a backflow device?
Irrigation systems connected to a public water supply must have a backflow prevention device and be inspected each year, per Charleston-area municipal guidance. For low-hazard residential lawn systems, state rules call for a written cross-connection control policy and a testing schedule for double check valve assemblies or other testable assemblies.
How long does a backflow tester certification last?
A tester certification is valid for three years. Recertification is done through a three-day state-sponsored workshop that costs $250.00 per person. You can ask to see the tester's current certification card before the work starts.
What should a James Island irrigation backflow quote include?
Ask for the test fee in writing, since the state rule allows the required testing fee to not exceed $50.00 for low-hazard residential lawn irrigation. Confirm the tester will submit the results to your water provider. Request proof of the tester's state certification card and insurance.
What to do next
