I'm installing a WC sink combined unit, The current pan connector/soil stack is behind a false wall (in eaves of house) Soil stack is cast iron.

Using a standard pan connector on the soil stack will not work as its too far forward of the unit.
I have purchased a mcalpine 40mm offset connector, this should enable the connection to come inside the unit. How do a connect a flex connector to this offset conenctor to then link to the pan?

I also have an issue where I cant reach the 40mm waste in the wall/eaves that runs from the bath to tap into for the sink. I cut an access panel in the plaserboard (in blue on image) but its a fair distance back, i dont think I can get in to cut/weld the new connection/t piece.
Could I add another connection inbetween the 40mm offset and flex pipe to introduce a 40mm connection?

That looks like a recipe for a blockage at some point in the near future.

What is the connection at the cast iron stack - a stub of cast iron or a socket?
