What Is Backflow Prevention?
Backflow prevention protects your home’s water supply by stopping dirty or contaminated water from flowing backward into clean lines. When water pressure changes unexpectedly (such as during a pipe burst or heavy usage) it can cause pollutants to enter your drinking water. A backflow preventer keeps water moving in the right direction, protecting your family’s health and ensuring your system remains compliant with safety codes.
