For good and sufficient cause, the Plumbing Inspector may revoke the registration of any journeyman plumber, and thereafter he or she shall not be permitted to do business or work as a journeyman plumber within the city or on premises connected or to be connected with the city water or sewer system.  In the event of the revocation, the holder of the registration may appeal to the City Council and the action of the City Council thereon shall be final.
