In regards to the 3" we are starting with the 3" LS 1/4 bend at 45 degrees to the wall behind the toilet and using the 45 st el to get parallel with the wall. The sewage ejector inlet center line is 18 inches from the wall behind the toilet, toilet flange is 12" from the back wall so I will need to add a short 3" dia. piece between the 3" 90 and the 45 to get lined up with the pit inlet. I will also have to add a 3" dia. piece into the upper end to get to floor level.
I'm trying to get the 2" into a wall behind the toilet. I'm not sure I following your idea with the 22 els. roll the wye up 22 degrees from horizontal, then I'm not getting it.
