RPZ Backflow Testing

Backflow prevention devices are used to protect the Village’s water supply from contaminants and pollutants. Common uses for backflow devices are fire sprinklers, lawn irrigation, chemical injectors, fountain drinking machines, machine shops, and car washes to name a few. The backflow devices on these service lines will stop contaminants from flowing or siphoning back into the water mains. Residences or businesses that have these devices must have them tested annually by a licensed plumber that is certified to test rpz’s by Ordinance 96-47.

Please be advised that the Village has contracted with Backflow Solutions Inc ( BSI ) to administer our Cross-Connection Control / Backflow tracking program.  As of September 1, 2013, all test reports must be submitted via BSI Online at www.bsionlinetracking.com.  Please contact BSI at 800-414-4990 or bsionline@backflow.com with any questions.
