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 ?

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