The Saniflo range would not be suitable as they do not allow a
vertical run at the end, only at the beginning.

One can go from the 22mm Saniflo outlet pipe to a larger size near
the vertical drop though. This will allow air in and thus not siphon
the whole of the 22mm pipe.

Using such a device may also allow other locations to be considered.

While any added complication is best avoided if possible these pumps
are useful in some situations and work happily for a long time if
not abused.
