    Default Can I roll a Wye to 45 degrees?

    Phoenix AZ here (UPC).

    My main 3" drain line is quite deep. To tie the rest of the fixtures into the horizontal main, can I roll a Y up 45 degrees to make the other lines more shallow?

    Alternatively (or in addition to) can I use a 45 to make steep depth change and then level off before entering the Wye?

    Yes. Ideally the inlet of a wye will be anywhere from right on top to 45 degrees to either side of the top. Given proper pitch, it can be rolled all the way down to 90 degrees from the top, but that is usually avoided.

    short of rolling it upside down you can pretty much do anything you want with a wye. Cacher's explanation is good

    There is absolutely NOTHING wrong with laying a "Y" on its side, therefore it can be rotated 180 degrees from one side to the other. HOWEVER, depending on which direction you will be going from the "Y" will determine what fittings to use because a 45 elbow will ONLY straighten it out parallel to the pipe if the "Y" is NOT on its side or perfectly vertical.

    Thanks for the responses! So now that we've established that a Y can be rotated 180 degrees, what about a 45 coming off of it? If I want to roll a Y up to 45 degrees, then put a 45 off of it going off to the side (to attached to a horizontal drain which will empty into the main) can I do that or does the code say no? Or is it a bad practice? Please see attached picture for reference:

    If it makes the angle you can most certainly go right ahead
