Floor mounted toilet to wall mounted

[arunraj.in]

Hi all

I am trying to install a wall mounted toilet in my bath. Currently the waste line is for floor mounting. I have broken the concrete and have the ABS drain pipe accessible. I will be building a narrow wall in front of the existing wall to run waste line and water line.. also will be installing the in-wall flush tank and frame in this new wall. he question I have is on routing the waste plumbing into the wall. Can someone suggest what all fittings to use here? in the picture attached I have shown a blue pipe where I am planning to have the new in wall waste line, The black lines show where the new wall will be.

Can I just use a sweeping 90 and go up and then again another 90 to come out of the wall ?

Why would you want an in the wall tank,just seems like it would be tough to work on that how is the toilet vented????

You'd have to do a lot more demo to get a the correct drain piping to work there. I doubt a Ram-bit chowdering out the fitting will provide room for the needed long sweep 90 because height could be a big problem.

Thank you guys for helping me out. I opened up the floor more to make things clear. Please find attached pic. The toilet outlet connects to a double sanitary tee. Drain line from bath tub is connected to the the 2nd inlet of the tee. Outlet from the tee goes to the main drain under ground. The upper outlet goes to the over the roof vent. Drain line from washbasin is also connected to this line. So the vent is for bath tub + toilet + wash basin. We are planning for wall mount toilet for the aesthetics factor. Planning to build a narrow width wall just in front of the current wall - inside which the in-wall flush will sit.

Should I replace the double sanitary tee or can I just do a 90 elbow to bring the pipe up and then another 90 elbow for the pipe to come out of the wall ? I was thinking of using a medium sweeping 90, but looks like that will be difficult. Will 2 X 90 elbows cause clogs?

Two 90s would be inviting clogs. a 45 horizontally would be fine. The fitting on the bottom of a wall closet assembly is very close to the floor itself, so I don't think there is room to have what you describe.
To do it right, you'd need to get rid of the side inlet fitting, tie that in lower down off a separate tee, and swing the 3" tee to project where the WC needs to be.
We use no-hub fittings when messing around with fine adjustments.

Thank you very much for your suggestions. It's a bit difficult to tie on the main drain line. So will the plan attached work? The toilet waste in will face outward from the wall and a back to wall toilet will be connected here- couldnt manage to draw that way.. so just showing sideways.

I would say 'yes', but it all depends on how low the toilet tee actually is, because the distance developed by the long sweep which comes off the toilet tee and points up is critical.
