Your talk of problems with toilets backing up got me thinking. Maybe you could
make the drain lines oversize the next time you do any work. Of course, it isn't
going to help to make the drain lines 8" in new suites if they drain into older
6" lines further downstream, but, if they don't, it'll reduce clogs.
