If required, drawings or blueprints shall accompany the application, showing the piping in its entirety as to the length of the run, size of the same, etc.

§ 120-4 Stopcocks.

There shall be a heavy main fullway cock on every service pipe close to the inside of the foundation wall, and in case there are two or more meters supplied from one service pipe, there shall be an additional straightway cock at the inlet side of each meter.

A. 
No pipe shall be laid so as to support any weight, except fixtures, or be subject to any strain whatsoever.

B. 
No drop or bracket shall be taken from an ell; it must be taken from a tee fitting, and the pipes must be run not less than four inches longer, or to a bearing, and be capped and securely fastened on both sides of the tee so as to prevent movement when the fixture is attached.

All brass tubing shall be at least No. 18 standard gauge. All threads on brass pipe shall screw in at least 5/16 of an inch.

A. 
Nothing in this chapter shall prohibit the extension of a gas pipe from a building located on the front portion of a lot to a stable, workshop or building of a similar character located on the rear of the lot if there is no gas main in the rear alley or street and both buildings are located on the same lot and owned, occupied or used by the same owner.
B. 
No extension or alteration of any existing system of gas piping in a building in excess of 15 feet in length, and unless the same is entirely exposed, shall be made without reporting the work to the office of the Plumbing Inspector for inspection and approval. Extensions shall conform in size to the table in § 120-10 of this chapter and shall be made where the proper size pipe can be maintained, and in no case shall extensions be made from smaller pipe.

Where necessary to cut pipe for extensions or repairs, pipe shall be again put together with right and left couplings, and in no case shall unions or running threads be permitted.

§ 120-16 Venting.

All gas appliances, including gas ranges and all types of gas water heaters, shall be connected with a vent to a chimney or flue. In cases where this is impossible, the vent shall be run to the outside of the building and shall be installed subject to the approval of the Plumbing Inspector.

§ 120-17 Air test.

Upon the completion of any system of gas piping in any building, premises or establishment and before the piping is enclosed, covered or concealed, it shall be promptly reported to the Plumbing Inspector for inspection. The outlets shall be suitably capped and the system tested with air to a pressure equal to a column of mercury six inches high in the length of time as will satisfy the Plumbing Inspector that the work is sound and tight. No piping shall be covered up nor shall any fixture, gas heater, range or appliance be connected thereto until the test is approved.
