This is a really clean build of this washing machine box, stand pipe, and P-trap. If only I was so lucky to have this much space. Anyway, I have a couple questions about the P-trap and spacing...
Check out the attached picture. Isn’t the P-trap supposed to be attached so that the vertical part of the P-trap is connected to the stand pipe? And the smoother transition of the P-trap follows onward from there? It is not like that in the picture.
Also, the washer is in the corner of a room and I have some space and obstruction issues that prevent me from putting the vent pipe in the same stud bay as the P-trap. Would it be ok to put the vent pipe into the next stud bay? In order to do so, the short piece of pipe connecting the end of the P-trap to the sanitary tee would have to include a 90 degree elbow because the next adjacent stud bay is on wall that is at the corner of the room. Does that make sense?
