Backflow Testing FAQs for Oklahoma City Businesses

How often does a backflow preventer need to be tested? Annual testing is required for all commercial backflow assemblies in Oklahoma City and most surrounding communities. Fire line backflow preventers are also required to be tested annually under fire code.

Do you repair backflow preventers? No. We test and certify backflow assemblies. If a device fails the test, we document the failure and refer you to a licensed plumber for repair or replacement. We can re-test after repairs are completed.

Why does my fire sprinkler line need backflow testing? Fire sprinkler lines can contain stagnant or treated water that must not flow back into the public water supply. Annual backflow testing confirms the prevention device is working, as required by both water utility and fire code regulations.

What happens if my backflow certification expires? The water utility may issue a notice requiring testing within a deadline. In extreme cases, water service may be interrupted until the assembly is tested and certified. Schedule your annual test before it expires to avoid this.
