RPZ Certification

The City of Oak Forest requires inspection of any RPZ/ Backflow Preventer at the time of installation and at least once annually thereafter by a licensed Cross Connection Control Device Inspector (CCCDI).  The device is installed for lawn irrigation systems, fire sprinkler systems, and commercial/ industrial occupancies to continually protect water supplies from contamination.
