Consider you have the layout in the first picture and consider that I want to replace the upstairs toilet with a floating one. For that to happen the plumber will have to do something with the drain for the old toilet and then cut the main stack (the blueish big vertical pipe) and connect the drain for the new toilet somewhere there.
Right now I am renovating the downstairs bathroom. I just realized that the plumber who will do the upstairs work might need to work from below to do a better job. You can see what it looks like from below in the second picture. The drain that needs to be removed is connected to the main stack just above the 10" mark on the tape, you can guess it there. What is the standard procedure in these situations what does the plumber do with the old toilet drain and when should I call the guy?
It might be too early from the upstairs bathroom perspective since I have not started the work there and I have not removed the horrible subway tiles that I currently have there. Do I have to call the plumber now? I would prefer not to but I am asking just because this is the last moment when I can still do that and allow him to work from below if he has to
