First post for a complicated problem. I have a '60s house with copper waste lines. The master en-suite was originally was plumbed with toilet and bidet against the wall. Complicating matters--the master en suite actually extends into the next section of the house (which is two steps down) so it could be level with the master bedroom.
The waste line from the toilet and bidet had to make a 90 deg turn and come back towards the outside wall and the vent stack is connected with a wye where it makes the turn. Either because of back wash or not enough drop on the vent line, it has corroded on the bottom and leaked waste into the crawl. So it has been out of service while I have worked on other things.
(I've attached a drawing and pictures of what I have because it is a bit of a nightmare and we simply can't afford the services of the plumber that I have worked with before, but for now while I'm doing other stuff, I wanted to start thinking about how to finish this $#@%^^& renovation.)
First order of business--repair the soil line (and I have to replace the section, since I had to redo the subfloor in the bath and already cut out the original soldered in toilet flange). So I already imagined cutting out the section of copper soil line, cutting the bottom of the vent where it has corroded and adding an appropriate replacement abs section with Ferncos and a new toilet flange.
Then I started thinking--if I am going to repair the soil line, can I install back to back toilets on the common wall? The adjacent room (now a furnace room) is at the lower level and would make an ideal powder room. The common wall between them would be framed up to enclose the existing vents; furnace relocated to the crawl (since it also needs redoing).
So I imagine if the soil line were relocated at a lower level to accommodate a new powder room toilet (spaced in about the same place as where the old bidet was in the master), it would mean that the master toilet would have to have a straight drop from toilet flange to soil line.
First question--can you have a straight drop from the toilet before connecting to the soil line and how would you make that connection--wye or?
Second question--is there a better way to redo the crazy over-under connection between the soil line and main--especially if I am adding a second toilet?
Third question--if I change the height of the soil line to allow for a second toilet, can there be jogs in the vent, since I can't see a way up other than how it is routed now, since the steel sits underneath that wall section.
