Irrigation backflow preventer devices are designed for installation on potable water lines to protect against both back-siphonage and back-pressure of contaminated water from sprinkler systems into the potable water supply. Backflow assemblies provide protection where potential health hazards exist.
A backflow prevention device is attached to the main water line from your home and prevents water from flowing back into your home's pipes. This is to prevent any contaminants from reaching your drinking water. It only allows water to flow in one direction, thus avoiding backflow. Backflow preventer device installation is required by law under certain circumstances such as at the source of a sprinkler system, irrigation system, or swimming pool.
