What Is Backflow and Why Does It Matter?

Backflow happens when water flows in the opposite direction, potentially drawing dirty water from irrigation systems, outdoor faucets, or sewer lines into your home’s clean supply. This can be caused by a sudden drop in water pressure or improperly installed plumbing connections.

Many homes are required to have certified backflow prevention devices in place, especially those with sprinkler systems, private wells, or pressure boosters.
