The problem is that I have just measured the inside of the old pipe
and it is approximately 105mm ie too small for the 110mm pipe!

I do not want to disturb the concrete where it joins a 90 degree
ceramic pipe (no collar on surface of garage floor), I have been to
a builders merchant who said I had to fit a rather unsightly black
plastic gaiter with clips, is there any other neater way I can do this?



Yes, there is a much tidier adaptor than the big rubber boot.
Unfortunately, none of the online suppliers seem to stock them, so I
can't post a link. Last time I bought one it came from our local City
Plumbing.

It's a piece of 110mm plastic pipe, perhaps 250mm long, which reduces
in diameter to about 100mm half way along its length. The narrower
section is fitted with rubber ribs, and is pushed into your iron pipe.


That's certainly the way to go: I'm pretty sure I've seen those fittings
on www.bes.ltd.com actually. But any decent plumber's merchant (not a
builder's merchant) ought to stock them - yours is by no means an
unusual requirement.

Thanks, BES does not seem to show them, but I will keep looking!
