The trap has to be right next to a joist for the tub I ordered. I had my tub drain and vent completely built out but frodo pointed out my crown vent. So I moved my wye further away from the trap. I can either fix this with a cut or try to refigure something else out. Im gonna try the cut bc I've got an extra 1/4 bend laying around. Just googled crown vents : "A "Crown Vent" is a vent that is located within 2 pipe diameters of the trap it is serving. When a vent is that close it is more subjected to fouling of hair, soap oils, grease, and other debris because; the flow of water does not have a chance to dissipate thus reaching the top of the pipe where the vent is during discharge causing premature failure.
