The Water Supervisor, or any of his authorized agents, shall have free access at all reasonable hours to inspect any premises supplied with water. No person shall refuse to admit authorized agents of the Water Department to any premises for such purpose. In case any authorized employee be refused admittance, or is in any way hindered in making the necessary inspection or examination, the water may be turned off from such premises after giving 24 hours notice to the owner or occupant thereof.
