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.

We love Nixco, they are extremely polite to us, solve all problems, and go above and beyond to make things right. Our last appointment was with Shawn and Kyle, to install a second floor washer. Small issues ensued, but they were resolved before the day was done! We love being able to call for issues knowing we will have a very qualified person working in our home .

Mason from Nixco Plumbing gave us options for repair or replacement. He had the part he needed in his truck and was able to successfully make the repair in about a half hour. He did a great job and was very pleasant.

I noticed my dump pump wasn’t working after looking at it I couldn’t find the issue. Called Nixco and the quickly scheduled an appointment for the next morning. Audie gave an ETA and arrived on time! He was very personable, knowledgeable and did his homework on our last repairs. He assessed the issue and much to our surprise, it was just the control panel in the battery back-up. No need for a new sump, only the battery & control panel. He also checked our hot water tank and noticed the expansion tank was faulty. Thanks Nixco for being honest and forthcoming…it saved us money & prevented emergency situations. Being a NIXCO CBustomer is well worth it!!!

Nixco came to inspect slow draining sinks in bathroom and replace the two u-drains as well as change two pop-up sink drains that were no longer popping up. Shawn Crank came as scheduled on time. Job was fixed promptly and left everything perfect. Shawn was very conscientious to make sure all was perfect and great to work with. Highly recommend.

My fault, 2.5 hours cost $600 an hour, I think that’s a bit much. It was the shower and I wanted it done.

In my experience, Nixco has some of the best plumbers we've used over the years. Today, Mason replaced our leaky bathroom faucet and had to do a deeper dive behind the faucet to get the job done. He was confident, efficient and professional. Thanks, Nixco, for doing a great job hiring great plumbers!!!

Had an issue with an outdoor faucet and a toilet that would not fill. Todd and Paddy arrived during the scheduled time window, assessed the issues and provided me with options on how to fix them. They took time to answer any questions, finished the jobs in a timely matter and cleaned up afterwards. Second experience with the company and no complaints.

I had a great experience with Mark Gossler at Neyer/Nixco Plumbing. My mother's hot water heater was leaking from a spot that the technician said was not usual. Instead of just replacing the part that was leaking, he spot checked multiple places around the house to find what was causing the leak and was able to fix all issues that day.

We recently required emergency services and called Nixco on a Sunday afternoon. Our technician Jared McCall arrived shortly thereafter. He quickly began accessing the issue using a camera and determined the issue must be outside the house. He located the sewer cleanout and using his auger and camera found we had root intrusion in our pipe. He was able open the clog but determined he needed to return the next morning with more powerful equipment to fully break through the roots, which was completed in about 90 minutes. We were completely satisfied with Nixco and Jared’s professionalism. We will continue to use Nixco for future plumbing services.
