    I would like to tie into the 3" cleanout in my basement where the main line enters under the foundation in order put in a small utility sink. Is it possible to add a riser to the threaded connection with a wye to attach a sink? I assume this would need to be vented. Would it be possible to use an AAE? Extending a vent through the roof would not be practical in this location.

    Thanks!

    Legally, no, and if it is a non-directional two way cleanout, then it would also be NO.
