The cover of the Y-branch or stub on the public sanitary sewer shall be carefully removed to avoid damage to the socket or bell. The first length of pipe attached to the Y-branch or stub shall be laid so as to give a good fall into the public sanitary sewer. The entire length of pipe on any house connection shall be laid in a straight line and on a uniform grade from a point three feet outside the wall of the building to be served, to the Y-branch or stub. Such grade shall be a fall of not less than one foot in 100 feet from the house to the public sanitary sewer, unless by special permission of the city, in which case provision must be made for regular and efficient flushing. Curved pipe shall be used for every deflection from a straight line of more than three inches in two feet. Unless otherwise specified in writing by the city, the manner of laying the pipe and making the joints shall be as follows:
(1) The sanitary service installed for a new building or when replacing an old or damaged sanitary service shall be made to a wye or tee. If there is no existing wye or tee, a new wye or tee may be installed or it shall be connected to a saddle, properly connected, in the presence of a city inspector.
(2) Except for multi-story residential structures, when one sanitary sewer lead serves more than one dwelling unit within a single structure, separate clean-outs may be provided for each dwelling unit and also for each end of the common lead and a clean-out shall be provided at the point where leads join to become a single lead.
