PVC at odd angles

Hayzee..that would be a great idea but it won't fly with code.

I started trying to put it together over the weekend and I think a 'real' solution occured to me. I'm _very_ rusty on geometry and trig, so bear with my inaxact jargon: If I take a 1/16 bend and rotate it along the axis of the pipe, I end up with some of the 22.5 degrees in the horizontal plane, and some in the vertical. I can rotate the 1/16'th until I correct for the orignal wierd angle, leaving me with some slant upwards. I can then rotate the 1/4 elbow to meet the upward slant.

In you were under the Uniform Plumbing Code the minimum angle for a vent is 45deg. but given that your existing vent runs horizontal, and assuming it was inspected when installed, it would then stand that you are under the International code, which permits flat venting.
