(A) The only approved type of backflow prevention is an air gap or vacuum breaker. Any mixing of liquids that does not have either of these devices is hereby prohibited as a cross-connection.
(B) The city, acting through its water superintendent or consulting engineer or their duly authorized assistants, shall direct investigations and keep suitable records of all premises, either residential, commercial, or industrial, suspected of having existing or proposed cross-connections with the municipal water supply.
(C) The city water superintendent or consulting engineer or their duly authorized representatives may enter upon any property of any residential, commercial, or industrial user of the water purveyor to inspect any suspected cross-connection violations of this section. Refusal to permit inspection by either the consulting engineer, water superintendent, or their duly authorized representatives shall be sufficient grounds to terminate water service.
(D) The consulting engineer or his agent shall order in writing the owner or occupant of any premises having or suspected of having any cross-connections to remove the cross-connections at his expense within twenty-five (25) hours of the date of receipt of the order to remove the cross-connections.
