What is a Customer Service Inspection (CSI)?

A customer service inspection is an inspection of a facility to determine if cross-connections exists or if there is the potential for a backflow situation to occur. A CSI must be performed in order for the Backflow Prevention Department to determine which type of protection is needed to prevent backflow or to eliminate cross-connections. A report is filled out for the facility and must be kept on file for ten years with the City of Red Oak.
