Backflow Prevention Testing & Repair in Xenia & Beavercreek, OH

Ever wondered how your wastewater doesn’t contaminate your drinking water? Every pipe has a “backflow device” that makes sure everything flows in the right direction. However, if the backflow device is damaged or worn down, you could risk mixing your clean and dirty water in unhealthy ways. It’s critical to have your backflow tested on an annual basis to ensure the quality of your water supply.


Backflow, as the name implies, is when water flows backwards into a building or house. This typically happens when there is a major drop in pressure in the municipal water system and can be caused by water main breaks, faulty sewer line drainage, major flooding or a host of other disturbances. If left unattended, backflow can introduce harmful pollutants and bacteria into the water supply.


A backflow preventer keeps contaminated water from being pulled backward into the clean drinking water supply — a real risk any time water pressure drops unexpectedly, whether from a water main break, firefighting demand, or a pump failure. Most commercial properties, irrigation systems, and many homes in Xenia and Beavercreek are required to have a backflow prevention device tested annually to stay in compliance.



Louderback Plumbing is certified in backflow prevention testing and repair, and handles the full process: testing your existing device, filing any required paperwork with your water provider, and repairing or replacing the assembly if it fails inspection. We serve both residential and commercial backflow testing needs throughout Xenia, Beavercreek, and the surrounding Greene and Montgomery County area.

  • Q: What happens if my backflow test fails?

    A: If a backflow preventer fails testing, it typically needs to be repaired or replaced before it will pass. Louderback Plumbing can complete the repair or replacement and retest the device as part of the same service call in most cases.
