Backflow prevention devices are devices configured to prevent or avoid flow of a liquid (typically water) in a direction opposite to normal-use flow directions.

In irrigation, a backflow prevention device is required to be installed between the municipal water supply and your home or business potable water system for the purpose of preventing your irrigation system’s water from flowing backwards into the municipal water system, potentially contaminating municipal water supplies (yours and your neighbors).

Backflow prevention devices are required on all irrigation systems that are connected to municipal water supplies. Additionally, these devices are required to be tested annually by a certified backflow tester.

Failure to have a backflow prevention device installed and tested on an annual basis not only jeopardizes the health of you and your neighbors, but may also result in your water being turned off by your respective water purveyor.
