Brilliant Steve, that's the information I needed to know. Can you tell me

how
much of the CI pipe is sticking through the wall into the bathroom please ?


About 50mm.


Could you make the connection between them using two 90 degree bends ?


Funny, but that thought occurred to me over lunch.

Using two of these:

which can be cut to length so they fit together and form an "S" sort of

shape
from the pan to the CI pipe may help, and be a lot cheaper.


I didn't realise you could cut them to length. I'm not sure that the
four inches or so of gap which I'd have would be enough space to fit
those, though.

Would that fit into my CI pipe? I'm assuming it's 3 1/2", the same as
the soil stack.

Are you sure that the soil stack is only 90 mm (3.5'') in diameter Steve, as
anything less than 110 mm (4'') is not allowed for solid waste soil pipes. Have
you changed the use of the room into a bathroom ? Or was the room changed
around before you moved in to the house ?

Does the original WC connect to the pipe with a normal pan connector or is it a
bodge of different sizes of pipe ?

If you see he

All soil pipe is made in 110 mm, but waste water pipework is made in smaller
sizes because they don't take solid waste away, only dirty water.

If the CI pipework has been used originally for a kitchen or bathroom with no WC
then it would use smaller sized pipes, and may not have had the pipework changed
when the new use of a WC was planned. This might cause problems later you know.
