The chalet bungalow upstairs bathroom.

Are there likely to be any issues with arranging a short 45 deg. fall in
the toilet waste pipe?

The current plan is a vertical outfall terminated at a manifold above the
soffit. There is insufficient space to get this high enough to accept a
full *horizontal* run. Probably 2m level, 45 deg. bend, 800mm and another
45 deg. to the manifold.

the water will leave the solids behind......

I will arrange a vented (AAV) stack inboard to be higher than the basin
overflow.

that is going to be noisey .......
