When water flows in the opposite intended direction through a plumbing line, it's called backflow.  Our staff of experienced technicians is available 24/7. If you have a problem with your backflow that needs immediate care, we'll send someone over to take care of it right away. 


A backflow preventer stops backflow from occurring. It’s an automatic valve on a main plumbing line that senses when water is flowing in the wrong direction. The valve automatically closes when the device has to much pressure heading back into the city water system. When the water levels return to normal, the valve will open. Then your water flow will automatically be restored.

A backflow preventer prevents the water from a commercial or residential building from backing up into the city water system. This keeps the public drinking water safe from contamination.


According to Ohio law, all backflow preventers must be tested and certified every year by a trained certification specialist. At J&J Plumbing, Heating & Cooling we have several certification specialists on staff to make sure that your backflow preventer is working properly. We will also remind you every year when your testing needs to be done.

When we perform the test, we’ll make sure your valve is free from any debris and ensure the parts have free movement. We’ll replace any parts that are worn. We will use sanitary procedures to keep your water supply clean.

If you have recently received a letter from your water provider informing you that your backflow prevention device requires testing, just give us a call. We can walk you through the process and take care of the testing and all associated paperwork. If your business is in the Cleveland, Canton, or Akron area, you can trust us to install and maintain your backflow preventer.
