HI Folks
We had a lever-operated kitchen kitchen sink mixer tap fitted about four
years ago - in the past few months it's started dripping.
It has quarter-turn levers - I'm guessing that these operate ceramic valves?

If so - does anybody have experience of obtaining replacement valves,
and how are they fitted. I'm expecting that the lever is held on by a
screw, under the end-cover - but how do you get the conical cover off
without damaging the chrome?

Anybody been there & done that, successfully?

I notice that the Amazon item carries a 15-year guarantee - "(excluding
working and serviceable parts, abuse or neglect)" - we have pumped
well-water supply - so it's quite possible that some grit as found its
way into the valve...

Thanks, Adrian
