Backflow Testing & Certification Services in Columbus, Ohio

Certified Backflow Testing to Protect Your Water Supply

Backflow testing is a mandatory annual requirement to ensure that your drinking water remains safe from contamination. If your backflow prevention device hasn’t been tested or certified, you risk water shutoff by local authorities.

At The Waterworks, we provide certified backflow testing, certification, and repairs for homeowners, businesses, and municipal facilities across Columbus and Central Ohio. Our team ensures that your backflow preventers comply with all local and federal regulations, keeping your water supply safe and contaminant-free.

Call us today to schedule your annual backflow testing and stay in compliance!

What Are the Legal Requirements for Backflow Testing?

Federal and Ohio state laws require that all backflow prevention devices be tested annually by a certified backflow tester. These regulations help prevent contaminants, pesticides, and chemicals from entering the drinking water supply.

If your backflow device is not tested, local authorities may shut off your water supply. Each device has a unique serial number for tracking, and all testing and repairs must be completed by the property owner.

At The Waterworks, we make the process easy and hassle-free by handling:

  • Certified backflow testing
  • Official documentation & compliance reporting
  • Backflow device repairs and replacements (if needed)

We provide same-day testing and repairs, so you can stay compliant and keep your water safe.   

Why Is Backflow Testing Important?

Backflow prevention devices protect public and private water supplies from contamination caused by:

  • Pesticides & Fertilizers from irrigation systems
  • Chemicals & Industrial Waste from businesses and manufacturing facilities
  • Sewage & Wastewater from damaged plumbing lines
  • Fire Suppression Systems that can allow stagnant water to enter drinking supplies

Benefits of Annual Backflow Testing

  • Protects your home or business from water contamination
  • Prevents serious health risks from chemicals & bacteria
  • Ensures compliance with Ohio state and federal regulations
  • Avoids costly fines or water shutoffs

If you have a sprinkler system, irrigation system, or fire suppression system, backflow testing is required to prevent contaminants from entering the municipal water supply.

What Is Backflow & How Does It Happen?

Backflow occurs when water flows in the opposite direction than intended, allowing contaminants to enter the clean water supply. This typically happens when there is:

  • A sudden drop in water pressure (such as a water main break or high demand)
  • Cross-connections between potable and non-potable water sources
  • Improperly installed backflow preventers

A properly installed backflow preventer acts as a barrier, stopping pesticides, chemicals, and waste materials from contaminating your water supply.    

What Happens During a Backflow Test?

During a backflow test, The Waterworks’ certified technicians will:

  1. Shut off the water supply to inspect the backflow prevention device.
  2. Check test cocks and shutoff valves to ensure proper function.
  3. Use specialized pressure gauges to measure differential pressure readings.
  4. Identify leaks, pressure issues, or faulty components.

If any issues are detected, our team can immediately perform the necessary repairs—saving you time and money.

Unlike some companies that only certify devices, The Waterworks provides both testing and repair services in a single visit.

On a Tuesday evening at 5pm, we described the problem to Waterworks expecting to have to wait a couple of weeks for an appointment. Instead, they were able to get us on the schedule for Thursday afternoon (only 2 days later)! That day, Brian, our plumber, called and texted to say he when he would arrive, and he did right on schedule. He looked at the problem and identified a couple of different ways it could be handled. Then, Brian looked at pricing for each option to determine the one that was most long lasting yet cost effective. He then worked quickly but carefully to complete the job. And Brian did a great job cleaning up! Couldn't be happier with the job.

We use Waterworks as a contractor partner with our family business. Had a residential issue that needed attention and gave the Works a call. Scott was dispatched and arrived within an hour of my call. This is how Waterworks, well, works. They work hard from the front office to the site experience. Waterworks has: —responsive customer service —are organized and connected with their office and field teams —have highly qualified techs/certified plumbers that can address both non-complex and complex issues. —they are courageous, neat, and professional —they elevate their responses to the situation Call out to SAM who helped me today with a non -urgent issue and he did a great job. Not only did he do the work, he took time to educate me. He was prompt. On time, and as I indicated, very professional. I HIGHLY recommend Waterworks for any need you may have. You’ll be pleased with their service. Top level management and strong certified field team with excellent customer service.

I cannot say enough good things. This is the second time Waterworks has saved me from another big name company that tried to upsell me and deceive a single female homeowner into major repairs. I was told I needed a 3,500 dollar repair and Waterworks inspected and fixed it for 500. Customer for life!!

Someone's day is about
to get better.
