Further to the bathroom renovation, I need to fit a shower
mixer
(Triton Aire bar type). The instructions call for it to be
connected to a half inch BSP female fitting where the face of
the
fitting is flush with the finished (tiled) surface. It's
going onto
a dry lined wall and I intend to run the supply pipes up the
wall
from the floor. My problem is that a standard BSP elbow
fitting is
too short to reach through the plasterboard and tiles and a
standard
soldered elbow plus straight BSP connector will be far too
long.
Approximate distance from solid wall to tiled surface will be
40mm.
Anybody got any experience of this or could offer any
suggestions -
it must be a common problem. Only solution I can see is to
cut the
plasterboard and tile over the gap, but I'm not very happy
about
doing this.

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?

15mm compression fittings have a 1/2" BSP thread, so how about
removing the
nut from a FI coupler (Screwfix 12341 or what I think you are
calling a
straight BSP connector ) and screwing it into a wall plate elbow
(screwfix
17416) fixed to the solid wall. Haven't got the bits to hand
right now to
check but I think the distance is approximately correct and the
wall plate
could always be packed out from or chased into the solid wall to
tweak the
level. If you use enormous quantities of PTFE tape between the
two bits,
you can make a watertight seal by screwing the fitting only
partially into
the wall plate, just as you would with a bib tap in order to get
it
vertically aligned - this would give a further adjustment.

Thanks Adrian

I did wonder whether the fittings might work as you suggest, but
didn't have any to experiment with. I'll get a wall plate and give
it a go. Incidentally, I emailed Screwfix about their fitting kit,
but they were unable to provide details and have referred me to
their supplier. I'm a bit surprised by that, but may give it a go.
Thanks again.
