I need to run my trap arm from the p trap to the main drain under the tub so it runs parrallel to the tub (looking at tub, tub drain is on left and main line i'm draining into is on the right running perpendicular to the tub). Can i attach a vent in the trap arm with a 45 wye say 3' from the p trap so the wye goes up but at a bit of an angle so i can go towards the back wall of the tub and up the back wall of the tub to tie into a vent in the ceiling? I'm a little confused how else to do it.
