Irrigation backflow refers to a phenomena where water in your irrigation system can reverse direction and flow back into the potable water supply of your community, thus polluting it.

This occurs due to a drop in water pressure within the system, usually caused by a sudden demand for water elsewhere, such as happens when water hydrants are opened to fight a fire. When that happens the water pressure to homes drops, and that drop in pressure can signal a reversal of water flow in homes.

Irrigation backflow preventers do not allow this reversal of flow to happen.
