I am installing stackable washer and dryer in custom built area behind wall at rear of new cast iron tub. Is it code that I have to have 3" drain for washer because it is on second floor? If so, I will have to cut out a section of 4" cast iron drain pipe below joists of second floor bathroom and install PVC 4 x 4 x 3" insert. Please respond.
Thanks!
