Backflow Prevention Device and Annual Testing

What is a backflow prevention device? Backflow is the reversal of the normal flow of water. It's caused by pressure differences and can allow contaminants from an irrigation system, boiler, or other source to enter a home or building's plumbing system or the public water supply.

Backflow prevention devices protect plumbing systems and our public water supply by preventing backflow.
