Before any devices or assemblies for the prevention of backflow or backsiphonage are installed, they shall have first been certified by a recognized testing laboratory acceptable to KDHE. These authorities include the American Society of Sanitary Engineers (ASSE), American Water Works Association (AWWA), University of Southern California Foundation for Cross Connection Control and Hydraulic Research, Canadian Standards Association (CSA), International Association of Plumbing and Mechanical Officials (IAPMO) or Factory Mutual (FM), and other testing or certifying authorities that may be accepted by KDHE. Devices or assemblies installed in a building potable water supply distribution system for protection against backflow or cross connection shall be maintained in good working condition by the customer. The Backflow and Cross Connection Enforcement Official shall inspect such devices or assemblies or may require the devices or assemblies to be inspected by a certified backflow inspector and if found to be defective or inoperative shall require the repair or replacement thereof. (Ord. 20196 § 5, 7-23-19.)
