Would this setup work for a wet vent? I'm converting a single vanity to a double vanity. The drain/vent is on the far right. It's about 3 feet center to center of the first vanity. It's about another 3 feet to the vanity on the left. I"m wanting to see a 90 degree elbow on the left vanity and a combo tee/wye on the right vanity, which then hooks into the drain/vent.
