The parents bought new taps for the bathroom and d/s cloakroom.
The instructions from one manufacturer say that the sealing washer
should go between the tap and the basin.
The instructions from the other manufacturer say that the sealing washer
should go underneath between the basin and the locknut.
Now, I don't see any functional difference in the design of the taps,
their sealing washers or locknuts, so the question is, which is right/best?
I would have thought that the washer should go under the basin; if you
put it on the top side, it creates a visible black ring or shadow gap.
