What is a backflow preventer and why do I need it? Homes built in Arizona with a front yard landscape already installed, usually have a backflow preventer installed. If your house does not have one already in place, then you must have one in order to have an irrigation system.
The backflow preventer is designed to stop the back flow of water from your irrigation system to your house and the city or well water system. The valves in the sprinkler system will not do this alone, thus a backflow preventer is needed. Landscape irrigation water is considered a contaminant and can introduce chemicals to your house and your drinking water. In Arizona, you are required to have a backflow preventer on your irrigation system. If your landscaper says you do not need one then find a new landscaper. The valves will eventually leak or break and without a backflow preventer installed, all the contaminants in your yard and ground water will come into your house.
