I've got a monoblock tap fitted to a washbasin but it seems the basin hole is a mm or so too big as there is a small gap between the edge of the tap and the edge of the basin hole, meaning water can easily go through.
Do monobloc taps and basin holes come in standard size or do you need to choose taps of the right size to overlap fully the hole?
