Shower into toilet drain

[bill emery]

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.

so i can have a shower drain then P-trap then vent, then toilet santee fitting with the 2in drain from the shower draining into the santee fitting then 3 in line out of the house? so the shower would be up stream from the toilet, all flowing out of the house

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.

Will this work?

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.

combination Y 1/8 bend then into the 3 inch drain.

The combination is combination of wye and 45 (1/8 bend).

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.
