What is a backflow device? 
Backflow devices are required by State law where fire or irrigation services are installed. The device prevents back siphonage and backpressure into the main water supply, protecting the water supply from cross contamination.

Testing: All installed devices must be tested on an annual basis. Each year, customers will receive a reminder notice along with a certified list of testers. Failure to have the device tested could result in the termination of service.
