(a) If in the judgment of the Plumbing Inspector, after inspection, the plumbing or plumbing system in any building are unsafe or dangerous to persons or property, the Inspector shall have the power to cause the plumbing or plumbing system to be disconnected from the supply of gas or water and may, at his or her discretion, seal the control valves for the same in a closed or disconnected position, whereupon he or she shall give notice to the owner, or his or her agent, or by posting such notice at the site and shall also notify the utilities serving the premises. Thereafter, it shall be unlawful for any person to cause or permit gas or water to be supplied to the plumbing or plumbing system so sealed until they shall have been made safe and the Inspector shall have issued a certificate of approval to that effect.
(b) When the Plumbing Inspector condemns all or part of any plumbing system, the owner may, within ten days after receiving written notice thereof, file a petition in writing for review of the action of the Plumbing Inspector by the governing body, upon the receipt of which the governing body shall at once proceed to determine the facts, and within ten days from receiving the petition make a decision in accordance with their findings.
