Be it ordained by the City Council of the City of Boston as follows:

Section 1. No person shall carry on the business of plumbing unless he shall have first registered his name and place of business in the office of the Inspector of Buildings, and notice of any change in the place of business of a registered plumber shall be immediately given to said inspector.

Sec. 2. Every plumber, before doing any work in a building, shall, except in the case of the repair of leaks, file at the office of the inspector, upon blanks to be provided for the purpose, a notice of the work to be performed; and no such work shall be done in any building without the approval of said inspector.

Sec. 3. Every building shall be separately and independently connected with the public sewer, when such sewer is provided; and, if such sewer is not provided, with a brick and cement cesspool, of a capacity to be approved by the said inspector.

Sec. 4. Drains and soil-pipes through which water and sewage is used and carried shall be of iron. when within a building and for a distance of not less than five feet outside of the foundation-walls thereof. They shall be sound, free from holes and other defects, of a uniform thickness of not less than one-eighth of an inch for a diameter of four inches or less, or five thirty-seconds of an inch for a diameter of five or six inches, with a proportional increase of thickness for a greater diameter. They shall be securely ironed to walls, laid in trenches of uniform grade, or suspended to floor-timbers by strong iron hangers, as the said inspector may direct. They shall be supplied with a suitable trap, placed, with an accessible clean-out, either outside or inside the foundation-wall of the building. They shall have a proper fall toward the drain or sewer, and soil-pipes shall be carried out through the roof, open and undiminished in size, to such height as may be directed by the said inspector; but no soil-pipe shall be carried to a height less than two feet above the roof. Changes in direction shall be made with curved pipes, and connections with horizontal pipes shall be made with Y-branches.

Sec. 5. Rain-water leaders, when connected with soil or drain pipes, shall be suitably trapped.

Sec. 6. Sewer, soil-pipe, or waste-pipe ventilators, shall not be constructed of brick, sheet-metal, or earthenware, and chimney-flues shall not be used as such ventilators.

Sec. 7. Iron pipes, before being put in place, shall be first tested by the water or kerosene test, and then coated inside and out with coal-tar pitch, applied hot, or with paint, or with some equivalent substance. Joints shall be run with molten lead and thoroughly calked and made tight. Connections of lead pipes with iron pipes shall be made with brass ferrules, properly soldered and calked to the iron.

Sec. 8. Every sink, basin, bath-tub, water-closet, slop-hopper, and each set of trays, and every fixture having a waste-pipe, shall be furnished with a trap, which shall be placed as near as practicable to the fixture that it serves. Traps shall be protected from syphonage or air-pressure by special air-pipes, of a size not less than the waste-pipe; but air-pipes for water-closet traps shall not be of less than 2-inch bore for thirty feet or less, and of not less than 3-inch bore for more than thirty feet. Air-pipes shall be run as direct as practicable, and shall be of not less than 4-inch bore where they pass through the roof. Two or more air-pipes may be connected together or with a soil-pipe; but in every case of connection with a soil-pipe such connection shall be above the upper fixture of the building.

Sec. 9. Drip or overflow pipes from safes under water-closets and other fixtures, or from tanks or cisterns, shall be run to some place in open sight, and in no case shall any such pipe be connected directly with a drain, waste-pipe, or soil-pipe.

Sec. 10. Waste-pipes from refrigerators, or other receptacles in which provisions are stored, shall not be connected with a drain, soil-pipe, or other waste-pipe, unless such waste-pipes are provided with traps, suitably ventilated, and in every case there shall be an open tray between the trap and refrigerator.

Sec. 11. Every water-closet or line of water-closets, on the same floor, shall be supplied with water from a tank or cistern, and the flushing-pipe shall not be less than one inch in diameter.

Sec. 12. Pipes and other fixtures shall not be covered or concealed from view until after the work has been examined by the said inspector, and he shall be notified by the plumber when the work is sufficiently advanced for inspection.

Sec. 13. Plumbing-work shall not be used unless the same has first been tested by the said inspector with the peppermint, ether, or water test, and by him found satisfactory.

Sec. 14. No steam-exhaust shall be connected with any soil or waste pipe, or drain which communicates with a public sewer.

Sec. 15. Water-pipes in places exposed to frost shall be packed with mineral wool, or other substance equally good, and they shall be cased to the satisfaction of the said inspector.

Sec. 16. A grease-trap shall be constructed under the sink of every hotel, eating-house, restaurant, or other public cooking establishment.

Sec. 17. The provisions of Sections 3-13, inclusive, and of Section 15 of this ordinance, shall apply only to buildings erected, or to work performed, after its passage. March, 17, 1883.

Approved.

Albert Palmer, Mayor.
