I think the steel pipe will just be sitting there, no socket other than the part
that has broken and just the mortar will have been holding it in place. Now
that it is broken I don't think you can rely on it sealing properly again so a
rubber sealed adaptor socket is the way to go. I think your confidence will
be raised if you go to your PM to have a chat and see what they have.
Locally I have a drainage specialist who doesn't stock regular plumbing
stuff at all and it is there that I would go if I was in your spot, perhaps you
have a similar outfit in your area. Ideal would be to remove the steel pipe to
check socket & pipe dims but I can understand you not wanting to do that
until you get the necessary bits. Get the to the PM :-)

Thanks Fred - yes I'm sure you're right about the mortar being the only
seal. I didn't mention it before, but in fact if you look at the photo
(http://tinyurl.com/ap2fg), at the very back of the area now exposed by
the lump having broken away, there is a cavity beneath the mortar seal,
which AFAICS goes right round the pipe. There was the rotting remnants
of some sort of fibrous material inside there, which I suspect may have
been some form of spacer or washer? Make any sense? Also, if you look
at the base of the lump which has broken away (now positioned upside
down) you can just see annular grooves, with a corresponding pattern on
the opposing face in the pipe. I'm wondering whether this lump has not
broken off the pipe per se, but off a separate annular component? Might
make a difference as to whether the Kwickfit adapter will work?

Anyway - having reinspected the 'project' this morning, I find that
there is certainly no easy way to raise or move the steel pipe; it goes
upwards through the ceiling (mating with the loo upstairs) and then
continues straight up through the roof to a vent cowl. It's all very
rigidly fixed and sealed in place and would be a nightmare to shift it.
So I'm thinking, cut through the pipe about 1m above the floor so I
can move out the bottom section. How would I successfully rejoin the
cut ends - another Kwickfit adapter, assuming there's a suitable one
available?

Oh, deep joy...

Btw, the fact that it has leaked at all (if the socket wasn't broken before)
suggest that the soil pipe may be backing up a bit, just thought I'd mention
it.
