10-3-5: PERFORMING PLUMBING WORK:
   A.   Permit Required:
      1.   It shall be unlawful for any person, firm or corporation to proceed with any plumbing work connected or to be connected with any pipe or pipes in the city or to any private plumbing or any sewer system of the city until a permit for such work has been obtained from the plumbing inspector. No permit shall be required for the making of minor repairs unless a portion or a section of the plumbing or drain line is cut, removed or replaced.
      2.   Applicants for the permit described herein shall, prior to proceeding with any work requiring such permit, call the office of the plumbing inspector and give the name of the plumbing contractor who is to do such work and the address where the work is to be done. The contractor shall be furnished one copy of the permit. (1991 Code § 4-25)
   B.   Submission Of Plans:
      1.   The plumbing inspector may require the submission and approval of plans and specifications in duplicate showing the nature and extent of the proposed work before a permit is issued. If, in the course of the work, it is found necessary to make any change from the approved plans and specifications on which a permit has been issued, amended plans and specifications shall be submitted and, if approved, a supplementary permit shall be issued to cover the change after the same conditions required to secure the original permit have been satisfied.
      2.   Plans and specifications, when required by the inspector, shall include a plane view and a riser diagram showing the work and shall show the direction of flow, pipe size, grade of horizontal piping, elevations, drainage fixture unit loading of both stacks, drains or drain waster and vent, the supply fixture unit load for water system and branch supplies which serve more than one plumbing fixture, appliance or hose outlet. Symbols used thereon shall be in accordance with standard engineering practice.
      3.   Nothing in this subsection shall be construed to prevent the issuance of a permit for the installation of part of a plumbing system before the entire plans and specifications of the system have been submitted or approved, if adequate information and detailed statements have been presented for the same and have been found to comply with the plumbing code. (1991 Code § 4-26)
   C.   Inspection: It shall be the duty of any person, firm or corporation doing any plumbing work and who has obtained a plumbing permit to report the same for rough-in inspection as soon as such work is ready for inspection, and when the work is ready for final inspection. (1991 Code § 4-29)
   D.   Alteration After Inspection: It shall be unlawful for any person, firm or corporation to alter or change any pipe or fixture or to remove any material or fixture after inspection has been made without first obtaining a permit from the plumbing inspector to do so, and the plumbing inspector shall then reinspect all work altered or changed, and the same fee shall be charged as hereinabove provided for original inspections. (1991 Code § 4-33)
