Your irrigation system helps keep the lawn healthy and beautiful. But, did you know it can also contaminate your family’s drinking water? Chemicals and microbes on the lawn can flow back through your home’s plumbing and even into the neighborhood water mains under low-pressure conditions. These conditions can occur when fire hydrants are in use, and during water main breaks.

A backflow prevention device has been installed on your system, per the State Department of Health (DPH) code, to prevent this contamination.  For you and your neighbor’s safety, DPH requires that you have your backflow device inspected annually to ensure proper performance.
