(A) Size and slope of sewer.
(1) The size and slope of the building sewer shall be subject to the approval of the town; but in no event shall the diameter be less than four inches.
(2) The slope of the four-inch pipe shall not be less than one-eighth inch per foot.
(B) Grades for sewers. 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 load bearing wall which might thereby be weakened. The building sewer shall be laid at uniform grade and in straight alignment insofar as possible. Changes in direction shall be made only with properly curved pipes and fittings.
(C) Building drains. In all buildings in which any building drain is too low to permit gravity flow to the public sewer, sanitary sewage carried by that drain shall be lifted by approved artificial means and discharged to the building sewer.
(D) Angle of connection. The connection of the building sewer into the public sewer shall be made at an angle of approximately 45 degrees. A 45-degree ell may be used to make the 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. Special fittings may be used for the connection only when approved by the town.
