Default Plumbing For 2nd Floor Bathroom

Looking to add a 2nd floor bathroom (shower, toilet, sink). Existing
home has bathroom on 1st floor with cast iron pipe drains. Would like
to get some info as to how to plumb new PVC drainage run into existing
cast sewer pipe, as well as venting into existing stink pipe.


You can NOT connect the 2nd floor waste lines into the
existing stack on the 2nd floor.

To do this job you will have to run a new stack inside the
wall(s) and connect to the old stack *below* the lowest 1st
floor fixture. If your town will allow 3" PVC (not all will),
you will at least have an easier time of it.

The top of your new stack can tie back into the old one
to avoid having to punch another hole in the roof.

Pick up a Basic Plumbing book that shows remodeling jobs.
There are many good books that will show exactly what to do.
