(A) The building sewer shall be cast iron soil pipe, ASTM specification or equal; vitrified clay sewer pipe, ASTM specification or equal; or other suitable material approved by the Inspector. Joints shall be tight and waterproof. Any part of the building sewer that is located within ten feet of a water service pipe shall be constructed of cast iron soil pipe with leaded joints. Cast iron pipes with leaded joints may be required by the Inspector where the building sewer is exposed to damage by tree roots. If installed in filled or unstable ground, the building sewer shall be of cast iron soil pipe, except that nonmetallic material may be accepted if laid on a suitable concrete bed or cradle as approved by the Inspector.
(B) All joints and connections shall be made gas tight and water tight. Cast iron pipe joints shall be firmly packed with oakum or hemp and filled with molten lead, Federal Specification QQ-L-156, not less than one inch deep. Lead shall be run in one pouring and calked tight. No paint, varnish or other coatings shall be permitted on the jointing material until after the joint has been tested and approved.
(1) All joints in vitrified clay pipe or between such pipe and metals shall be made with approved jointing material in accordance with the latest edition of Volume III, Plumbing Rules and Regulations of the Administrative Building Council of the State of Indiana.

Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor. No building sewer shall be laid parallel to or within three feet of any bearing wall, which might thereby be weakened. The depth shall be sufficient to afford protection from frost. The building sewer shall be laid at a uniform grade and in straight alignment insofar as possible. Changes in direction shall be made only with properly curved pipes and fittings.

The connection of the building sewer into the public sewer shall be made by the "Y" branch, if the branch is available at a suitable location. If the public sewer is 12 inches in diameter or less, and no properly located "Y" branch is available, the owner shall, at his or her expense, install a "Y" branch in the public sewer at the location specified by the Inspector. Where the public sewer is greater than 12 inches in diameter and no properly located "T" branch is available, a neat hole may be cut in the public sewer to receive the building sewer, with entry in the downstream direction at an angle of about 45 degrees. A 45-degree ell may be used to make such connection, with the spigot end cut so as not to extend past the inner surface of the public sewer. The invert of the building sewer at the point of connection shall be at the same or at a higher elevation than the invert of the public sewer. A smooth, neat joint shall be made, and the connection made secure and watertight by encasement in concrete. Special fittings may be used for the connection only when approved by the Inspector.
