What is a backflow preventer and why do I have it tested?


Water that flows in your home should only flow in one direction. Clean water enters and contaminated water exits. Back flows can happen due to a sudden change of water pressure which can force unsanitary water into a lower pressure area like your home’s or community’s drinking water supply.

These changes can occur for many reasons, some reasons this can occur would be a water main break, a clogged irrigation system, or a hydrant flushing.


Many businesses are required to have backflow preventers and some residences are. Your home may be required to have a backflow preventer if you have a water-driven backup sump pump, irrigation system, or fire protection system.
