    Default Ugh. Tapping into sanitary T below basement slab.

    Need to run 2" shower drain to this 3" stack. Wasn't expecting a long sweep sanitary T to be just below the slab. Cutting out the T isn't much of an option since there's fittings immediately to the left and right so no open run for a union.

    Maybe a saddle of some sort? Cutting/jacking out more of the slab is not a good option.

    Could sure use some helpful suggestions. Photo is rotated 90 deg - damn iPhone.

    Much thanks.

    A sanitary tee would not be permitted in that position; that is a TY fitting.
    Your connection will need to be made further downstream in the horizontal run. The shower will also need a separate vent.

    Not what I was hoping to hear but probably the only acceptable solution.

    Thanks for the replies.

    Default drain

    NO SADDLE!!! And your shower drain will have to have a vent.
