What’s a Backflow Preventer — and Why Do You Need One?
A backflow preventer keeps contaminated water from flowing backward into your clean water supply. Changes in water pressure, nearby hydrant use, or heavy water demand can all increase the risk of backflow.
A properly working device helps protect your home and your community’s drinking water.
💧 Pro Tip: Have your backflow preventer tested annually by a certified technician.
