The Importance of Backflow Preventer Maintenance


What is a Backflow Preventer?

  • A Backflow Preventer is a device that prevents water from flowing in the wrong direction.

  • Backflow Preventers are used to prevent contamination of drinking water.

  • Backflow can happen when rainwater, pool water, or other sources enter your home's plumbing system through the pipes and fixtures. This can lead to contamination of your drinking water if not properly handled by a backflow prevention device such as an air gap or check valve (the most common type).


Two main types of Backflow Prevention Devices. 

The two main types of Backflow Prevention Devices are Check Valves and Pressure Vacuum Breakers.

Check Valves are used in situations where water is flowing in one direction only.  They prevent water from flowing back into the main water supply by closing off the flow of water when it senses a pressure difference between two sides of their internal mechanism, which means they're ideal for use with gravity-fed systems like rainwater collection systems or ponds that don't have pumps running constantly (like farm ponds).

Pressure Vacuum Breakers are used in situations where water is flowing in both directions. They work similarly but also have some built-in safeguards against overpressure--they'll automatically close if too much force builds up against them after an extended period without being used!


Why do I need to have my Backflow Preventer inspected?

Your Backflow Preventer needs to be inspected because it is a requirement of the State of Ohio. The inspection ensures that your backflow preventer is working properly, ensuring that you are not polluting any nearby bodies of water. Additionally, it certifies that your backflow preventer is free of any flaws that might be problematic for you or other people who frequently use it.


What types of Inspections are performed on my Backflow Preventer?

  • Visual Inspection

  • Functional Test

  • Pressure Testing (Hydrostatic Testing)

What happens if I fail the Backflow Inspection?

If the inspector finds a problem with your Backflow Preventer, they will notify you. You will be required to fix the problem and pass another inspection before you can use your water system.

You may also be charged a fine for failing an inspection or not having a permit on file with the city.

If necessary, you may be required to have your backflow preventer tested again to obtain a new permit.


You need to schedule routine maintenance for your Backflow Preventer.

  • Routine maintenance is an important part of keeping your Backflow Preventer in good working order, which can save you money on repairs and equipment replacement costs.

  • Not doing regular inspections could result in a costly repair or even replacement of your system.

Make sure your Backflow Preventer is inspected annually by a certified technician.

  • Make sure your Backflow Preventer is installed correctly.

  • Make sure it is maintained properly.

  • Make sure it is tested annually by a certified technician. 

  • Inspect and repair your Backflow Prevention device if necessary to ensure that it performs following its intended purpose of preventing cross-connection between potable water systems and non-potable sources.
