I have a tap which I believe was made in Italy probably more than 30 years ago. It is hard to turn off fully, even after replacing the washer, and I assume it needs the seat grinding. Unfortunately the thread into which one expects to screw the grinder does not match any of the threads on the grinder I have. Can anyone identify the thread, and ideally tell me where I can get a tap grinder that will screw into it, or best of all (a really long shot!) an adapter that will enable me to use the grinder I have.
The grinder thread needs to be (as near as I can measure) 19.7mm outside diameter, with a 1.2mm pitch. In case it helps someone to recognise the tap, the tap washer is 15mm diameter (I believe this is unusual in the UK). An adapter for my tap grinder would need to fit onto a shank 2.6mm in diameter.
