(A) General.
(1) Upon completion of installation, alteration, or repair of gas piping, and prior to the use thereof, the Building Inspector shall be notified that gas piping is ready for inspection.
(2) Excavations required for the installation of underground piping shall be kept open until such time as the piping has been inspected and approved. If piping is covered or concealed before approval, it shall be exposed upon the direction of the Building Inspector.
(B) Required inspections. The Building Inspector shall make the following inspections, and shall either approve that portion of the work as completed, or shall notify the permit holder wherein the same fails to comply with this subchapter.
(1) Rough piping inspection. This inspection shall be made after gas piping authorized by the permit has been installed and before any such piping has been covered or concealed, or any fixture or appliance has been attached thereto. This inspection shall include a determination that the gas piping size, material, and installation meet the requirements of this subchapter.
(2) Final piping inspection.
(a) This inspection shall be made after piping authorized by the permit has been installed, and after all portions thereof which are to be covered or concealed are so concealed and before fixtures, appliances, or shutoff valves have been attached thereto.
(b) This inspection shall include an air-pressure test, at which time the gas piping shall stand a pressure of not less than ten pounds per square inch gage, or, at the discretion of the Building Inspector, the piping and valves may be tested at a pressure of at least six inches mercury, measured with a manometer or slope gage. Test pressures shall be held for a length of time satisfactory to the Building Inspector but not less than 15 minutes, with no perceptible drop in pressure. For welded piping, and for piping carrying gas at pressures in excess of 14 inches water column pressure, the test pressure shall be not less than 60 pounds per square inch and shall be continued for a length of time satisfactory to the Building Inspector, but not less than 30 minutes. Tests shall be made using air pressure only and shall be made in the presence of the Building Inspector. Necessary apparatus for conducting tests shall be furnished by the permit holder.
(C) Other inspections. In cases where the work authorized by the permit consists of a minor installation of additional piping to piping already connected to a gas meter, the foregoing inspections may be waived at the discretion of the Building Inspector. The Building Inspector shall make such inspection as the Building Official deems advisable in order to assure that the work has been performed in accordance with the intent of this subchapter.
