Finally getting to fitting the sink in my d/stairs bog. *The sink is a
B+Q 'to go' cloakroom job with a single tap hole while the tap is a

but the hot control lets water through to the heater, displacing water
from the heater unit).

Anyway, the hole in the sink is slightly conical at the top, while the
base of the tap has a rubber O-ring. *When I tighten the bolt that
holds it all together, the tap slips out of the vertical into the
dished/conical top of the hole, so won't sit straight. *I don't think
there's anything missing from the kit - it's more likely that the B+Q
sink is carp - and the only way I can see to keep things right is to
put something between the tap and the sink to stop it, for example a
flat plastic washer. *This looks like a bodge, even though the washer
is translucent, but I could try trimming it once the whole thing's in
place. *Alternatively, I could be missing something here so I thought
I'd post and ask if anyone had come across this problem and had a
better solution.

Sadly the box (and probably the receipt) has long gone so no going
back to the orange shed!

Dave - Do you reckon they would go into the top and keep things
steady? Only it says they're not for monobloc taps (which I would
have got the most benefit from that type of washer).

As far as I can see, the problem is a combination of the top of the
sink, where the tap meets it, not being flat and the fact that
monobloc-design taps are held in place by an offset stud and not.
Tightening generates an uneven force which, in this case, makes the
base of the tap slip onto the 'ole, kinda skew. If the tightening
pressure was even, I'd expect the tap to burrow a little into the
conical hole and settle there but the best I can get it is sort of
metastable, ie, it looks right, it's tight, then you touch it and the
whole thing slips!
