I need to take a T off a 22mm pipe (and off an old imperial pipe the same
size), but it doesn't look like there will be any play in the pipe to get
the new fitting in. Any ideas?

Conex compression - you need about 1cm max play - do you not have even that
much flex?

Otherwise chop a section out and use a solder slip coupling to insert a new
bit of pipe to join into the tee (can be slid onto one pipe fully, then
slid back over the other pipe).

Chop a lump out and use plastic or a flexible connector or even a bendy
corrugated copper section.

You could cut the tube back further and do it with two elbows and a T.

You could drill out the central flange in the T and slide it right
over one pipe first if there is enough lateral play.

Thx to you and Robertl - just the advice I needed. I haven't cut the pipe
yet, so I'll just try an ordinary tee first, then if that doesn't work I'll
move to plan B with the slip coupling.

BTW, is there a preferred type of plastic pipe for hot and cold feed to a
shower? In the past I've always used copper, but something flexible would
work better here.

Actually that was Tim's idea :-)

You're welcome

JG Speedfit (pushfit) is good IME. There are other (incompatible) types. JG
will pushfit onto copper too (I polish the ends of old copper with fine
gauge wire wool)

That's a good way. I was after some recently though and my local local
plumbers merchant (PTS) told me that they didn't bother stocking them
anymore because everyone is going to plastic/push-fit. They still
stocked a good range of ef/sr copper fittings though, so I don't know
why slip couplers have been dropped.
