I'll rephrase my comment. The way it is now does not meet the IPC code. You need to start the entire thing over.

You can never drain any fixture at any time into the branch of a tee on its back. That is the first thing I see picking up the lav. If you place a wye to a shower between the toilet and its lav, you will need to vent that shower vertically.

I'm looking at those pics again. That drain line doesn't look very deep. That fitting may not work. How deep is the 3" line below the floor surface?

Ghost, if he uses the fitting I linked in #13 would that fix the problem with the horizontal T and allow the shower and WC to be vented by the existing lav vent?

Are you willing to move the toilet to another location?
Can you upload a floor plan of proposed fixture location so we can find an alternative vent location?

Thats a 25 dollar fitting. Why not just start over and do it right from the start. Move the toilet position so you have room for a 3 by 2 wye and can go back with a 2 by 1.5 wye to the lav and vent. 2 inch to shower. Now we have a wet vented bath.

Ghost would this work for him?

Fitting "A" is a San-T
Fitting "B" is a 3" Wye
Fitting "C" is a 3x3x2 Wye
Fitting "D" is a Wye or a Vent Tee and would come up inside a wall built for the shower.

Then tie the vent into that stack above the flood level of the lav? Hopefully there are no other fixtures from the above floors draining into that stack

took your idea and tried to have it make sense to me. what do you guys think?

- delete the T going out of toilet into vent
- run the drain all the way to shower vent so that i can vertically vent it out
-whe in the shower drain to toilet drain

Ghost...the reason he can have the Wye that I have circled flat is because its being washed by the lav correct??

Under IPC the lav is wet venting the shower and the toilet. A wye is what he needs there. He needs to use a sanatary tee when he picks up his lav sink in the vertical.

He only needs 2 inch to that lav wye and shower. 1.5 inch on the lav drain from the tee in the wall.
