I note that Screwfix have a special fitting for bar mixers -
somebody else asked about these recently, but I can't recall seeing
any replies. Does anybody know whether these fittings would help?

I'm guessing you mean Screwfix item 56419, right? Two components, one for
each 15mm pipe. I bought this a while ago to fix the wonky mixer valve a
builder left me with, and it does seem quite good although I have yet to
actually get round to fix it (on investigation I found further problems
which need sorting, ie seemingly the builder left me with such massive
access holes in the plasterboard below the tiles that I've nothing to attach
the fitting to!)

The chrome 'drums' in the picture unscrew to reveal a steel fitting beneath
with screw holes etc; and be warned that you need a massive spanner, of
about 2" across the flats, to fit these things; something Screwfix don't
mention when you buy it!
