    Thanks for the add. i am new to plumbing. I am redoing a bathroom and was wondering if i could drain the shower into the toilet? Shower would have P trap 66 in run to 1.5 in vent line to the roof. Then 20 in line and connect under the toilet into a 3 in line. Toilet has its own vent line to the roof. thanks for any help you can give

    A shower can come in downline of the toilet if it has it's own vent.

    The picture your words paint is not so good. Try a paint program to illustrate.

    You need a different fitting for the toilet. No santee in the horizontal for drainage. Somebody will have a specific suggestion I hope.

    California is UPC code, so your 66 inch should only be 60. Move the vent closer to the shower.

    For the fitting under the toilet would a combination Y 1/8 bend work? If I had to I would put a bushings in it for the shower to drain into

    Yes. I thought that was Option A. So are are you picturing the closet flange centered above? So all of that is in the same vertical plane? That would be ok, but not required. That would put the 3 inch pretty deep.

    Option B looks good if they are in different vertical planes. You might try adding an overhead view to go along with your side view.

    The 3 inch is very deep. This is under a mobile home. Lots of room down there. The closet flange would be centered above the 3 inch. Having 2 or 3 inches straight down under the closet flange then into the combination Y 1/8 bend then into the 3 inch drain. Everything is on the same vertical plane

    Sounds good.
    The combination is combination of wye and 45 (1/8 bend). [​IMG]

    If you use the two separate pieces, as in the picture, that gives an extra point of adjustment if that is needed. The adjustment may not be needed.

    Yes. I was also talking about an alternative. I was not suggesting PVC instead of ABS.

    Thank you for taking the time to work this out with me. I have the ABS fitting in the pic. It will go under the closet flange.
