As part of my 2nd floor bathroom remodel I am adding a double vanity. I have a 4" PVC stack with a 1 1/2" wye piped for the sink drains. The 1st sink is inches from the stack so I have a 1 1/2" wye that continues to the 2nd sink. The sink farthest from the stack is about 30". Do I need to re-vent the farthest sink? I'm well within the critcal distance for the pipe size. Thanks
