If you take a small circle blade that you can buy at hardware store and put it in a EL. drill and cut the flange off inside about 3/8″ below the bottom of flange and buy a 4×3″ pvc flange and glue it inside of 4″ pipe.I forgot is this in a wood floor are concrete, if it is wood then all you have to do is cut the pipe below and use a coupling and new flange, if con. then chop around if it is 3″and cut out flange.
