I just installed a Kohler Archer in my Bath remodel. When installing the drain pipe on the tub prior to setting it in place I thought I had it installed straight. Once in place, from the basement you can see it is slightly misaligned from being perfectly vertical to the existing drain pipe, the overflow socket down pivot to allow this. What can I do to make up for this slight angle and make the connection? Are there and PVC/ABS joints that pivot some to make up for the difference? Any sort of flexible P-Trap units? Thoughts?
