The building sewer shall be laid at uniform grade and in straight alignment insofar as possible. All changes in direction and/or depth shall be made through the use of pipe fittings meeting the same specifications as set forth in § 1042.09 to tie in existing building sewers and the test tee required at the property line. No angles, either horizontal or vertical, shall be greater than 45 degrees along the length of the building sewer.
(Ord. 1979-33, passed 5-7-1979)
The building sewer shall have a minimum fall of one-eighth inch per linear foot from the building to the public sewer. The City Engineer may, by special permission in each case, authorize the building sewer to be constructed with a fall less than one-eighth inch per linear foot if he or she determines such procedure to be necessary and desirable.
(Ord. 1962-69, passed 6-4-1962)
The interior of each length of pipe shall be made perfectly clean and free from offsets, fins and projections before the next length is connected thereto. All building sewers shall be graded by line and pole, the line being first leveled from the building to the lateral or public sewer and then lowered at the lateral end to obtain the required fall.
