 move flanges and get pipes in wall
Author: Pipe runner (AZ)

Have a project to move one upstairs flange (the bend painted white) over one joist bay. The cast iron fitting is back to back with the WC in adjacent upstairs apartment. Project 1

Because of a new door being added in basement apartment no pipes can be coming out of wall. So the vent for basement lav and shower needs offset taken out and upstairs tub rerouted. Project 2.

Any thoughts on cutting CI and demo and as well routes for new ABS piping? thanks for any input. Good news is that I have plenty of time on this one.

I'd start by pulling the toilets, cutting out all of that cast iron and start anew at the basement floor. Just lay a 3" wye and 45 flat against the wall to get over in the other joist bay to catch the other toilet. There's a wire stapled exactly where you need to drill thru the joist so you'll need to move it. The holes in the floor for the cast iron flange may be too large to work well with the ABS flange so you'll probably need to add some wood so that you can screw the new flanges down.

well thanks NCP ! I appreciate the advice.

got a good start on that yesterday.


Now you are dead on about the floor needing repair.
I've put this back onto the general contractor to repair the
floor. We'll shall see what happens with this.
Seems to me that floor repair falls under carpentry.
