Caple Atlanta Tap Leaking

[dave40]

Hi everyone - here's my question:
On my kitchen sink I have a Caple Atlanta monobloc single lever mixer tap, with a lift and swivel mechanism top. The tap is slowly leaking from the top and running down the pillar - when I remove the swivel top, there is water around the joint/workings but I don't know if this is a washer problem, and if it is, how to get to the washer and replace it. Grateful of any advice. Thanks, Dave. ps I'm a bit of a plumbing novice.

Probably an O-ring seal that has gone - you'll need to know the right size and how to get at it - change the tap.
