Backflow Testing

Backflow is the term used to describe water moving the opposite of its intended direction.

It can occur following a water main break, frozen pipes, or reduced water pressure. With an underground sprinkler system, this can become a serious issue because the lines used to water your lawn and landscaping are the same lines that supply water to your home. Backflow could result in contaminated water from fertilizers, pesticides, bacteria, etc. entering your drinking water, creating a real health hazard.

To safeguard against backflow, most Northern Virginia water authorities require a prevention device on your source line and annual testing of the device by a licensed, certified professional to ensure it’s in working order and keeping your water supply safe.

Our professional crews are certified in backflow testing and have the experience and knowledge to get the job done thoroughly and properly.
