Are all 1/4 turn taps of the ceramic disc variety? The one I've just looked at is a monoblock kitchen mixertap with 1/4 turn between open and closed and they are not only quite stiff (so much so that one of the plastic handles has rounded splines and wont turn the valve ) but have a 'plasticy' feel to them, different to my own which I know are ceramic discs.
What is the most cost effective way of sorting this out?
