Is it possible to have too much venting on a line? I have a water closet that flows 4" to a wye that goes to a tub. Another 6" down that line is a 1 1/2" vent that is only attached to the 3" drain. Another few feet down the drain is a 2" vent for the toilet. Does that first vent even need to be used? the toilet is 6'4" from 2" vent which I know is slightly too far. Does the 1 1/2" vent make this 4" excessive distance acceptable or do I need to make the 1 1/2" vent a 2" vent? Thanks.
