I have fitted a monoblock to a new sink and it is leaking. On investigation the leak is caused because of a poor seal between the tap and the sink. The water supply to the tap is fine.
I removed the monoblock and the problem seems to be because of the size of the sealing o-ring under the tap.. The o-ring is the same size as the hole in the sink and therefore does not provide a watertight seal.
Any ideas on how I can get the tap to seal - the only thing I can think of is to apply some clear sealant around the tap - but that's not going to look to good and probably will not last that long.
