Got a Backflow Test Notice From Your Water Utility?
Water utilities send these letters to customers with a backflow assembly on file. If you got one, here is what to do:
- Read the notice for the deadline and which assembly it covers.
- Have a certified tester test it. The utility only accepts results from certified testers.
- Make sure the passing result is turned in to the utility that sent the notice.
- If it fails, repair or replace it, then retest.
Send us a photo of the notice with your address and we will tell you what is needed.
Who Needs Backflow Testing
- Homes with in-ground irrigation systems or pools, where the utility requires a protective device.
- Businesses and commercial buildings, where assemblies are typically tested every year.
- Any assembly that was just installed or repaired.
Why Backflow Is Tested
Backflow is water flowing the wrong way through the pipes. If pressure drops, water from an irrigation system, boiler, or hose can be pulled back toward the clean supply. The device stops that, and the yearly test confirms its check valves still work.

Backflow Testing FAQ
I got a letter saying my backflow test is due. What do I do?
Check which water utility sent it (Columbia Water, West Columbia, SC Water Utilities, or another). Have a certified tester test the assembly and send the results to that utility by the deadline on the notice. Call or text us with the address and the notice and we will tell you what is needed.
How often does a backflow assembly have to be tested?
South Carolina rules call for testing after installation, after any repair, and at least once a year in most cases. Some utilities set their own schedule for certain residential irrigation systems, so follow the schedule on your notice.
Does my house need a backflow preventer?
Many homes do not. In West Columbia, for example, a home only needs one if it has an in-ground irrigation system or a pool. Businesses are different, and requirements depend on the type of building and water use. Your utility decides, so check your notice or call us.
What happens during the test?
The tester connects a calibrated gauge to the assembly with the water in a no-flow condition and checks that the check valves hold. Water to the property is briefly interrupted. The result is recorded on the utility's test form.
What if my backflow preventer fails the test?
It has to be repaired or replaced, then tested again before the passing result is sent in. Rules require a new test after repairs of any kind.
How much does backflow testing cost?
It depends on the type and size of the assembly and whether it needs repair. Call or text us with the address and what you have, and we will give you a straight answer. If we send a plumber out for an on-site inspection or repair, the $89 house-call fee is credited toward the job if you move forward.
