Hanahan, SC: what's different here
Hanahan sits in Berkeley County, with city limits touching the Charleston County line on the west and south sides. The area is mostly suburban, and single-family detached homes are the most common land use. Hanahan is about 16 miles and roughly 23 minutes by car from Charleston via the main highway.
How often does a backflow device need testing?
South Carolina requires backflow assemblies to be tested at least once a year by a certified tester. Testing is also required after installation and before the customer uses the system, and after any repair.
Who is allowed to test backflow devices in South Carolina?
Only a state-certified backflow prevention tester may perform the test. South Carolina recognizes four tester types: General Tester, Limited Tester, Inspector Tester, and Manufacturer's Agent.
Why does the price vary between homes?
Typical U.S. backflow testing runs about $75 to $200, and costs rise for complex or multiple-device systems. Routine tests in South Carolina commonly run about $50 to $250 per assembly.
What to do next
