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.

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

Generally best of you can do it near the source end, but usually ok so
long as most of the run is within the recommended falls (typically
between 1 in 10 and 1 in 80 for 110mm soil pipe).

Its quite common to need a little bit of pipe height adjustment near
soil stacks for example.

OK. Sadly the basin waste can't conveniently be used as a flush.

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

Our second toilet exits through the wall, turns 90° and then immediately
descends at 45° for about 800mm, before changing again to a normal
"horizontal" run. There was no choice, as there was a window half-way
down the stairs, between the toilet and the stack, preventing a straight
run. It has worked fine for 9 years now, but from the outside, it is
quite a bit noisier than the pipe from the other toilet.

Hmm.. I'll let you know how I get on:-)
