(A) 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, in-so-far as possible. Changes in direction shall be made only with properly-curved pipes and fittings.
(B) In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by the drains shall be lifted by approved artificial means and discharged to the building sewer. No water-operated sewage ejector shall be used.
