Before selecting a backflow preventer you must research the state and community laws regarding backflow installation types. You should select a backflow device that meets your watering or fertilization requirements. For instance, you may need a single device for a water hose, or one device which will protect an entire irrigation system. Some backflow preventers allow for the safe use of fertilizers in the irrigation system. Each device has a specific use for your unique irrigation system.

Yes, different irrigation systems may require specific backflow preventers. For example, drip irrigation systems might use a different type of backflow preventer compared to traditional sprinkler systems. It’s important to choose the correct device for your system’s design and requirements.

A backflow preventer attaches to the main water line from your home and averts water from flowing back into your home’s pipes and contaminating your clean water supply. It only allows water to flow in one direction, thus avoiding backflow. This is crucial for sprinkler systems and irrigation systems, where water in your yard might carry fertilizers, pest control chemicals, or other contaminants. Backflow preventer device installation is required by law under some circumstances, such as at the source of a sprinkler system, irrigation system, or swimming pool.

Irrigation backflow devices are designed for installation on potable water lines to protect against both back-siphonage and back-pressure of contaminated water into the potable water supply. Backflow assemblies provide protection where potential health hazards exist.
