    A wye and 45, sometimes called a combination fitting or combo.

    I've googled to the end and couldn't find a definitive answer, so I'm hoping to get it here.

    Is it possible to use a sanitary tee in a waste line on its side? I'm doing this to change directions/tap into an existing waste line.

    and from the differing answers I found, none of them gave a clue as to why this can't be done, other than to say it can't be done.

    You need a wye, or tee-wye. A horizontal to horizontal change of direction needs to be sweeping.

    the turn radius on a san tee is too tight, it will eventually have a problem with clogging.

    thanks for the quick replys.

    Sometimes, google isn't the best place for information.

    What about vertical to horizontal ? (Although I could feel advantage of
    45+wye in this case as well)

    horizontal to vertical, santee or wye unless the vertical is used as a vent, and then a santee.

    Are combo's OK? The type that is like a "T" but has a sweep 90 sort of with it?
    This is for a horizontal to horizontal.

    Yes, a store bought combo is also known as tee-wye. I hadn't seen them until recently, we made them up and always called them combos.
