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! Â
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. Â
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.  Â
What Happens During a Backflow Test?
During a backflow test, The Waterworks’ certified technicians will:
- Shut off the water supply to inspect the backflow prevention device.
- Check test cocks and shutoff valves to ensure proper function.
- Use specialized pressure gauges to measure differential pressure readings.
- 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. Â

Tech was very nice and serviced the air conditioner in a timely fashion with no problems.
I observed water backing up and fountaining from the outside downspout where it enters the ground during rainfall. To determine whether there was an underground blockage or another drainage issue, I contacted Waterworks for an inspection. The technician, Logan L., reviewed the situation, explained the range of possible causes, discussed potential outcomes, and provided sound recommendations for resolution. He was professional, courteous and very patient in explaining (and even re-explaining). When I need to work with Waterworks again, I would very much like to request Logan.
Look, sometimes your major appliances finally give out and when you’re faced with such situations, what you want is a reliable service that will help get your homestead back to normal operating order. That’s what these technicians (Conrad and Ryan) were able to do for me. They removed an 80gal hot water tank with nearly 2 decades of accumulated sediment out of one helluva tight utility closet in a condo. Installation of new tank was performed seamlessly, and they were a couple cool dudes that made the time go by easily. Took 1 business day to get on the Waterworks’ books. Job wrapped up within 5hrs. Appreciate the quality work.
Able to reach Waterworks easily and set up appointment at convenient time. Chris was professional, efficient and pleasant. Answered all my questions and assured I was satisfied. Pricing was reasonable. Would recommend.
Worked with Jonle for years, on repairs to original furnace then eventually when did a new system. They're always very professional and answer all questions! Do the yearly tune up package for peace of mind to take care of system/ prevent problems! Highly recommend!
Waterworks wonderful experience. Todd shepherd was at my facilities the next day and took care of the issues. Friendly fast and efficient.
Victor was great at identifying the blockage in my basement floor drain and quickly resolved it. Thx!
We have seasonal checkups and are very satisfied with all aspects of the services provided. A couple of years ago we needed to replace our old HVAC systems, and that process -- sales and installation -- was also excellent.
Our tech was friendly and professional. He did a great job and communicated clearly. He turned off all the lights in the basement when done saving me time to not walk downstairs to turn them off, very conscious. Paperwork was electronic and speedily sent upon completion of the work. The dispatch personnel are pleasant to talk to, they are helpful and responsive. We have been using Jonle for many years and will continue due to the great service. We participate in the annual contract that gives two maintenance tune-ups, on for winter and one for summer. If problems arise the maintenance plan provides availability above non plan members, parts are cheaper and other perks.
My technician was very professional and helpful with getting our A/C working. I highly recommend JonLe for all your HVAC needs!
I have had the maintenance service for years, and every technician that has come to my house has been on task, courteous, and respectful of the property. I really like that the company sends a photo of the technician and a brief description prior to his arrival. Any work they have done, including installing a new air conditioner and heat pump, has been professional, and I highly recommend them.
Called and they came the next morning! Great communication - Matt did a great job and put everything back tidy and clean when he left. Couldn’t have been a better experience.
Technician investigated my problem and offered estimates on different options. Fee for trip was remarkably low.
Peter did a terrific job, analyzed the problem and fixed it in under an hour.
Great company, friendly employees - very satisfied with the twice yearly maintenance they provide.
Courteous, friendly and professional. I like gettong a reminder call a day or so out and the tech calling me to give me a heads up on actual arrival time. Eadily understood and communicative:)
A repeat customer here and as always, the experience was a great one. Experienced technician who knows their trade and is very efficient and courteous.
We had our new system installed by Jon Le. When built our house in 2021. They installed that one. So 24 years later when we needed a new system , there was no question. Their technicians are, friendly and knowledgeable. They serviced our system the first 24 years and we will definitely have them service our new one. Thank you for you wonderful service!!
I've depended on the services of JonLe Heating & Cooling for the past 5 years, and remain a happy customer. Their staff and technicians have always been kind, courteous, and thorough in their work. I'm grateful for the services they offer, and will continue to call on them. Thanks, JonLe!
We recently had our sump pump replaced by The Waterworks, and I couldn't be happier with the service. Our technician, Kameron Gates, was professional, courteous, and punctual from start to finish. He arrived on time, wore shoe covers before entering our home, and took great care to keep everything clean throughout the job. Kameron performed a thorough inspection, explained the condition of our old sump pump, and replaced it with a new one. What really stood out was his attention to detail and willingness to answer every question we had. He clearly explained the work being done and made sure we understood everything before he left. After the installation, he cleaned the work area thoroughly and left everything in excellent condition.
Jonle is always there when we need them, on time, professional, and clean. Recently Jason got our thermostat back online and took the time to explain itt to me.
We needed fire hydrant repair. For privately owned hydrants. I have used them multiple times they are always absolutely the best.
They were able to get me in and taken care of very ppromptly. Definitely the best service I have had done. Highly recommend.
I've used Waterworks 5 times now, and will again when I need plumbing work. Most recently, I needed a leak under a bathroom sink fixed and I also needed a new faucet. Todd Shepherd did a fantastic job! Very happy.
We have used Waterworks Plumbing for multiple commercial repairs and they have always done a tremendous job!
Mr Victor Gonzalez was awesome he did a great job and taking the time to explain everything
The service person who came was very kind and on time. I was hoping there was record of what electrician they had come out to install the outlet for my sump pump they installed 6 years ago, but they said they don't keep records that long ago which was unfortunate, since it the faulty outlet that stopped the sump pump from working which then caused my basement to flood.
Great service! The technician, Noah Pettit, showed up on time, explained what he was going to do, and then did it in a thoroughly professional manner. He was very friendly and courteous throughout.
Our technician, Wade, was exceptionally professional and knowledgeable. Despite having to work in a very tight space, he took extra care and spent additional time ensuring that nothing was damaged. His attention to detail and commitment to quality were greatly appreciated.
We have used JonLe for a very long time, over 20 years. Everyone has been friendly and very helpful. Will Ross was our technician this time. He was punctual and notified us that he was on his way. He answered our questions and did a great job with our A/C maintenance service. Thank you, Will!
I had a really positive experience with Water Works. They are one of the few places which will take Sunday calls. I called and the person I spoke to was professional. The technician Luke was out the next morning. The clog was cleared promptly. Thanks!
Mr. Sheppard did a FANTASTIC job. He took his time, was happy, friendly and respectful he explained what he was doing, explained our humidifier, air cleaner and thermostat (we just moved into a new home and no papers were left.) We would like to have him our system in the spring.
Our service tech Will did a great job. He was thorough and explained what he was doing
Excellent service; efficient with good explanation with digital photo of completed cleaning.
Fast and very thorough! The technician explained everything and let me know exactly what was going on the whole time.
Jon Le has been our go-to for annual AC/heating maintenance. Always quick to schedule and they listen to our concerns when we do have them.
I called this morning (Sunday) no doubt and they were courteous and on time and the tech guy pointed out the problems within seconds and will be back Tuesday hopefully to fix the problem. Thanks
