The condensate pipe from the boiler is solvent welded, and one of the
fittings had developed a hair line crack. I had to cut it out and put in
a new length of pipe, plus connector fittings in order to replace this
one joint. Did I miss a trick there for replacing it? And why would it
have cracked in the first place?

Dis similar expansion rates?

This is well down the condensate pipe, 2-3m from the boiler. So the
water must be room temperature.

Wrong solvent cement? They can be PVC or ABS and there are two different
types of solvent; one solvent is compatible with the other, but there is
a "wrong way round". Some plastics get brittle if exposed to the wrong
solvent.

No. This was under the kitchen sink.

The bit I had to cut out had a 90 degree bend and a 45 degree bend.
After I'd messed around for quite a while cutting little itty bitty
lengths of pipe and using 4 solvent weld fittings to replace it, I went
home and checked the www. I found:
http://www.screwfix.com/p/mcalpine-f...56-206mm/34977

So would that have done the job in 5 minutes? Plus 30 minutes to go and
get it, but still quicker than all the messing around.

Who knows, but could the problem be some strain, ie the angles of the pipes
have moved over time as hot or cold water flowed through the pip. You say it
should be room temp, but have you actually measured what it does?

As it's a waste pipe with no pressure I'd have painted the crack with solvent.

Someone has pushed something in the cupboard and it's either cracked it or
put enough strain on it that it's cracked over time?

Wrapping with pvc electrical tape also works.
