Backflow testing questions, answered

Backflow happens when water flows backward into the public water supply — potentially pulling contaminants from irrigation systems, private wells, or other sources into your drinking water. A backflow prevention assembly stops that from happening, and annual testing confirms it's still working correctly. South Carolina law requires it.

It depends on your system and your water purveyor. South Carolina sets a minimum of every two years (biennial) for low-hazard residential systems like lawn irrigation — but your local water purveyor can require testing more often, and many require it annually. We'll tell you exactly what yours expects.

If you have a backflow prevention assembly — common with irrigation systems, private wells, and most commercial properties — then yes. Your water purveyor and SC DHEC require regular testing to keep your water service compliant.

Most tests take about 30 minutes, during which your water supply is shut off. Your certified tester shares the results with you on the spot.

Yes. We file your compliance report with your water purveyor — typically within 24 hours of the test — and a copy lands in your free online dashboard.

A failed test means your assembly needs a repair or replacement. We'll quote the work, fix it, and re-test to confirm you're back in compliance.
