Daughters house in Cheyenne Wy, ~90 years old on a crawl. (Single story)
I am a lic MHIC contractor in MD, Flying out to get the 90 YO bathroom in shape.
I already replace all the beams with footers, piers and LVLs
Currently it is a 4" C.I. main line that 90s up as a main vent stack, and wyes off with a 4" C.I. to the W.C.
Off the W.C. branch is a wye tying in 1.5" galv to the tub (unvented),
The Lav tyes in the main 4" just before it 90s up as the main vent stack. The lav has a 1.5" vent tying into the main vent stack in the attic.
The entire 4" run of C.I. is supported by laying on loose brick scraps,, so 1st thing is a bunch of galv hangers.
The changes I am making is the new tub will be flipped right to left, and adding a 2x4 wet wing wall for the diverter valve and adding a tub vent.
The toilet will move about 6" to the left to maintain 15+ inches from the new wing wall. (still maintaining 15" on the right side)
I will be cutting the 4" C.I. W.C. branch and transitioning to 4" PVC with a banded coupler, (RED is new PVC in the proposed drawing)
Adding a PVC 4x4x2 wye to service the tub,, the tub will have a 1.5 or 2" vent.
Questions:
Does the W.C. branch need the "Tub vent" to be 2" ,, or is the main stack taking care of that?
Any issues with moving the wye that ties in the tub farther away from the main line?
The 4x4x2 PVC wye I will be adding,, can that be anywhere from vert (2" coming out the top) to Horz (2" coming out the side)
I am guessing it will be rolled up about 15-20 deg.
Any words of wisdom is appreciated.
