How Backflow Prevention Testing Works in Oklahoma City

Oklahoma City ordinances require annual backflow prevention testing for properties with irrigation, fire sprinklers, and certain types of commercial plumbing systems. The goal: prevent contaminated water from flowing back into the city’s public supply. Routine inspections make sure your backflow device operates as designed and maintains code compliance.

Routine annual checks: Most owners of commercial and certain residential systems must schedule yearly inspections to comply with state and local standards.
Certified test reports: The city requires documentation from a licensed plumber to confirm that your devices passed inspection.
Responding to failed tests: When a device fails, prompt repairs or replacement restore both system safety and legal compliance.
Council, school, and business needs: Schools, commercial sites, and government buildings face extra scrutiny and must keep current on their compliance testing or risk city fines or service interruptions.

Working with Hull Plumbing, Inc. keeps your property compliant with Oklahoma City ordinances, whether you need a single annual test, ongoing service, or support before a city inspection. Our team shows up with fully stocked vehicles, finishes the job efficiently, and provides easy-to-understand information about your results. We keep you one step ahead of city deadlines and promptly provide those test certificates so you avoid penalties.

The City of Oklahoma City sometimes requires you to submit your backflow test certificate as proof your system is up to standard. If you remodel, update your irrigation, or change property ownership, you may be asked to test again before approval. Our team stays familiar with these processes, so you can manage these transitions without extra stress or last-minute rushes. By opting for a local, licensed plumber, you maintain compliance, receive prompt communication, and keep your property safe for the long term.

Thanks guys!
“Just wanted to share my excellent experience with Hull Plumbing and their stellar technician Anthony M. Purchasing a home built in the 1960's can be stressful. I wanted to know what was lurking under the ground, so I picked Hull and gave them a call. Later that same day Anthony called and was on the spot exactly when he stated he would be. We spoke about my concerns, and I asked if he would take a quick look around the house and its fixtures before starting to send the camera down the sewer line. He happily obliged and then started the imaging. It was a long line and he took the time to point out the areas of concern and to describe what he thought it would be as a future problem. When he finished the job he gave me the video and made certain I was completely satisfied. Great job! I would just like to say that I have hired literally hundreds of folks over the years. It is one in a hundred that has the forward looking positive outlook shown by technician Anthony. If you are looking for a company to hire for your plumbing needs I can whole heartedly recommend Hull. If they have a crew of technicians with the attitudes, skill and drive show by Anthony then they will certainly get the job done for you. Thanks guys!”
