I just purchased a new garbage disposal. The current plumbing will not allow the new disposal to fit in place. The main sewage line with a wye is in the way and I need to replace it. This is a single sink single trap set up.
1. what is the best way to do this (see picture) 2. Can I cut the wye pipe just before the base and then use a saw of some sort to cut the remaining flange around the bottom? 3. Or, should I just cut the whole wye pipe out and install a new one?
