Why Backflow Testing Matters in Highland Park, IL (60035)

Backflow prevention devices protect the potable water supply from contamination caused by reverse flow in the plumbing system. Highland Park has a large number of residential properties with irrigation systems serving manicured lawns and gardens, boiler systems in mid-century and older homes, and commercial properties along Central Avenue and in the downtown district. Illinois requires annual testing of RPZ (Reduced Pressure Zone) backflow assemblies, and the Highland Park water department tracks compliance. Properties with irrigation systems are especially subject to enforcement because cross-connections between irrigation water containing fertilizers and pesticides and the potable supply pose a direct contamination risk. Boiler fill connections in older Highland Park homes also require backflow protection to prevent non-potable heating water from entering the drinking supply.
