(A) It shall be permissible for the city or county employees to cause inspections to be made of all properties served by the public water supply where cross-connections with the public water supply are deemed possible. The frequency of inspections and reinspections based on potential health hazards involved shall be as established by the city and as approved by the State Department of Public Health.
(B) The representative of the city or county employees shall have the right to enter, at any reasonable time, any property served by a connection to the public water supply system in the city, for the purpose of inspecting the piping system or systems thereof for cross-connections. On request, the owner, lessees, or occupants of any property so served shall furnish to the inspection agency any pertinent information regarding the piping system or systems on the property. The refusal of this information or refusal of access, when requested, shall be deemed prima facie evidence of the presence of a cross-connection.
