    The answer is quite simple...
    The horizontal drain requires the use of a wye and 45 or, a combo.

    Ty

    Actually, if you cannot see the reason by looking at the two different fittings, maybe you should not be doing the job. The TY, assuming you are referring to a sanitary tee and not a combination Y-1/8 bend, has negligable sweep and the code specifies the amount of sweep for ANY fitting below the overflow level of the fixture. If you are refering to a combo, then it is the same as a Y and a 1/8 bend/45.

    Both of these can be used on the horizontal

    The SanTee can not be used on it's back.
    It has to be vertical.
