(A) Construction materials and methods. The size, slope, alignment and materials of construction of a building sewer, and the methods to be used in excavating, placing of the pipe, jointing, testing and backfilling the trench shall conform to the requirements of the State Building Code or other applicable rules and regulations of the city. In the absence of code provisions or in amplification thereof, the materials and procedures set forth in appropriate specifications of the ASTM and WPCF Manual of Practice No. 9 shall apply.
(B) Building sewer grade. Whenever possible, the building sewer shall be brought to the building at an elevation below the basement floor.
