Saniflow connection to 32mm pipe?
 

About to commission a Saniflow into a 32mm vertical outlet pipe. The vertical section appears out of the wall to a short horizontal section via a slow 90 degree bend.

The horizontal section appearing out of the wall is about 40mm long ready for a 90 degree solvent connection to the Saniflow flexable fitting.

It strikes me that it would be better to have a semi-permanent fitting to the wall pipe, instead of a 90 degree solvent bend.

Words have been mentioned about a "Mcalpine" fitting that may be suitable, in that the joint can be broken easy for maintainance, should there be a blockage.

Ordinary compression or push fits are a NO in the this case.

ideas please?
