Question for the group. I presently have a double vanity that is drained by a two inch pipe. It is vented by a 3 inch DWV. The 3 inch waste passes through the floor and I would like to reduce it to a two inch pipe to connect to the main waste line. Would this be against code or do i need ti leave it as a 3 inch pipe. Also the distance to the waste line is around 6 feet
