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.

There are several kinds of sprinkler system backflow preventer or backflow preventer valve designs in use today. They range from simple to complex designs incorporating multiple fail-safes for protection. A backflow prevention device allows for water to flow in one direction into a system but will prevent any water from returning back into the potable water source. These variations are based on the irrigation needs of the property and the local legal regulations. Shop for your backflow preventer device today at Sprinkler Warehouse!

An AVB requires one unit per valve and most cities don’t allow them in irrigation systems. A PVB is similar to an AVB however it only requires one for the entire irrigation system. The RPZ allows for fertilizers in the irrigation system, a function that no other preventer performs. The DCA allows for the flow of pure water that is not susceptible to contaminants in the air.
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.
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.
