(a) The county administrator shall cause the inspection of the plumbing within every building and all water service pipes as frequently as in the county administrator’s judgment may be necessary to insure that such plumbing has been installed and maintained in such a manner as to prevent the possibility of pollution of the water supply.

(b) Agents of the county administrator, bearing suitable identification, shall have the right of entry into any building, during reasonable hours, for the purpose of making inspection of the plumbing system installed in such building, or premises, and water service pipes, for cross-connection or backflow problems caused by improper installation, repair or maintenance, faulty equipment or any other cause. Upon request, water system or property owners shall furnish to the county administrator pertinent information regarding the piping system on such property. In the event the owner or occupant of any building, including a building under construction, refuses to permit such inspection or furnish such information, the county administrator may order water service to such property terminated.
