What is a backflow preventer and why do I need one?
A backflow preventer is a device that allows water to flow in only one direction. Its purpose in an irrigation system is to allow water to exit a home or building for watering the lawn while keeping it from coming back into the building. A backflow device must be installed on all systems that tie it to a public water supply. These devices must be tested by a certified Technician annually. Our technicians are certified in Maine, New Hampshire, and Massachusetts to test and repair these devices.
