I have to bury a 1/2" BSP (using washer) and a compression joint inside
a (solid) wall, i.e. basically, no access from behind etc. (BSP
compression elbow behind bar mixer), I've done this before, no
problems, but I just wondered, what could I do to make leaks
"impossible". e.g. thread sealants, bandages etc. Any-one else bother
with this, or do we all just hope its all OK ?
Cheers,
Simon.

I would use jointing compound and look for any leaks before closing the
hole.

Screwfix (and no doubt others) offer something which allows one to
bring 15mm pipes out of the wall and into a compression fitting,
onto which bar mixers fit. Seems like a good way of avoiding a joint
in the wall to me.

You could slather it totally in chemical metal afterwards.

Pressure test it first. If it's to be driven from a shower pump then mains
pressure should do, if it's to run at mains pressure then it should be
tested with a pump which can deliver about half as much again as the mains
is likely to. You may be able to hire one (they're £100 to buy) but if
you don't do at least test at mains with hot water.
