Is it ok that my laundry drain trap is tilted?
It looks like the hole drilled on the outlet side of the p-trap needs to be enlarged so the hub of the fitting can slip in, thus leveling the p-trap, thus keeping it from sticking out of the wall, however, ideally, and by most codes, there needs to be a larger drop directly from the installed washerbox, because  as piped, when the washer drains, water will shoot right back out of the opening.  The y fitting in the stack where this drain connects, needs to be lower, and you can eliminate some couplings in the lateral, by feeding your piping from the end of the wall.
