What Is the Law Regarding Backflow Testing in Mason, OH?

By federal law, it is required that all backflow devices be tested annually. This must be performed by a certified backflow tester. If these devices are not tested, your water will be shut off by the local governing authorities. All devices have a serial number that allow for record-keeping. All testing and repair costs are to be met by the consumer.

Why Is Testing Important?

It is important to test backflow devices to make sure they are performing the necessary job of preventing herbicides, chemicals, and waste products from entering your drinking water. The entire community relies on the proper chemical makeup of the water coming from the treatment plant.

Though some homeowners find this task to be too much, the safety of your drinking water relies on the proper function of these devices. If any of these chemicals are ingested, they can cause serious illness and even death.

What Is the Testing Process?

The testing process of backflow prevention devices is quite detailed, but the general process can be explained fairly easily. The tester turns off the shutoff valve and checks all of the test cocks for proper function and flow. Then, a test kit is inserted at various valves and cocks. The tester then takes a reading of each check valve. Pressure gauges are used for differential pressure readings. Leaks and other problems are detected when readings are extreme.

What Is Backflow?

Backflow occurs when water flows in the opposite direction than intended in a plumbing or irrigation system. A backflow preventer keeps the drinking water safe by keeping chemicals and waste from entering the water supply.

If it is time for your annual backflow testing, call Nixco Plumbing Inc. to set up an appointment. We can also answer any additional questions you may have about backflow and the importance of testing. Do your part to keep our community healthy through prompt testing as required.

If you are ever concerned that your backflow devices may have leaks, we can also perform additional testing. The great part is that we can fix any problems that we find, whereas other certified backflow testers do not provide solutions to common problems. We have the experience and training to perform an accurate backflow test.

Are you in need of backflow testing and certification? Call (513) 457-0915 to schedule an appointment with our experts today.

Every service call we’ve had with NixCo Plumbing has been extremely professional. Called on Tuesday, Mason W and Kris B were out on Wednesday to provide estimates for what we thought was a serious water pressure issue raised by our RO water company. They tested and explained why their finding wasn’t as serious as we were told. There are items we have to discuss with our HOA before making any repairs/adding a pressure valve but I am extremely confident that NixCo will do a great job. There were a few other items we wanted estimates for (two leaky faucets, bathroom remodel/shut off valves needed and corrosion on water main). Mason and Kris checked those items out, explained what the work involved would require, then gave estimates for those as well. Very appreciative of their time and professionalism.

Our technician Shawn Crank showed up right on time and diagnosed and explained the situation of the sewer back up in the kitchen. He then fixed the flooded sink and to my surprise cleaned the kitchen sink, counter and floor. I was extremely pleased and can only recommend Shawn with NixCo. Plumbing. He went over and beyond of my expectations.

We experienced a water backup in the kitchen sink after not being in the home for almost 3 weeks. The kitchen was mostly flooded and the water seeped into the carpet of the dining and living rooms in the open concept condo. A neighbor recommended Nixco. We come down from Michigan, so were glad to get a recommendation. We called them and they sent Shawn out. Shawn was super friendly and professional! He saw the mess and also arranged for a restoration company right away. Shawn and his collegue did a wonderful job explaining what happened, fixing the issue, cleaning up and making sure that everything was left perfectly, including making us feel comfortable with the process! I would highly recommend Nixco, and especially Shawn! Thank you, guys!!

Nathan and Paddy came out to replace a pinched water pipe below my garage. They arrived when scheduled and completed it in one day, like they planned. They were both friendly and answered any questions I had. The job entailed jackhammering through the cement floor and digging about 4.5 feet down. They dealt with the challenges of the task. My water volume and pressure is now outstanding. As for the price, my condo association paid for it, so I have no knowledge.

John, Jason & Greg came and fixed our sump pump lines that lead to the storm sewer. After they assessed our situation they came bk with a back hoe in a timely manner . They did an exceptional job! All 3 were very conscientious, extremely polite & professional and were able to fix our sump pump lines in the front yard. They operated a back hoe & even saved our sod! Once everything was finished they put everything back and our yard looks great w the sod placed back over the giant ditch they had to make. The new sump pump lines are operating perfectly. I would highly recommend Nixco Plumbing!

We were thoroughly impressed with Nixco and their service technician, Chris McClure! We talked to Becky (the receptionist) at Nixco and requested Chris, due to wonderful reviews online he had for his work! Becky had Chris scheduled to be at our house the very next morning. Our kitchen sink was completely plugged up, and he finally had to go up on the roof and unplug the line from there. We are very grateful to Chris, and highly recommend him if you have plumbing needs!

They were patient with me and very sensitive to keeping my home clean by putting on and taking off shoe covers. I would hope either of these service persons would be my service person in the future, if needing service.
