What is RPZ backflow testing and why is it required in Deer Park?
An RPZ (Reduced Pressure Zone) backflow preventer stops contaminated water from flowing backward into the municipal water supply. Deer Park requires annual backflow testing for properties with irrigation systems, fire suppression systems, boiler connections, or commercial water equipment. Failure to test on schedule can result in water service disconnection or fines.
Why is backflow prevention important in Deer Park, IL (60010)?
Deer Park’s larger residential lots commonly include in-ground irrigation systems, swimming pools, and landscaping water features — all of which require backflow protection. Properties with well-adjacent plumbing or mixed water sources add additional cross-connection risk. Deer Park homes may have multiple RPZ devices covering different water uses across the property, each requiring separate annual testing.
