I know but the problem is its all glued so if I turned the pipe so that the elbow is facing upwards then the whole drain pipe would be pointing towards the ceiling. Its a single piece of pipe that goes through the bulkhead with the elbow glued at one end and the t-piece on the standpipe at the other. Really wish i'd have put a union on there or something now...I think @cboylan1606 was asking if you could turn the whole bulkhead, thus turning the pipe in your overflow box.
