So far as I can see, there is no scale present at all. We live in mid
Cheshire which is a very soft water area. I'm really baffled as to
why the 'drip' is occurring.

Noted. I certainly know that the water in the Manchester area doesn't
cause any scale, so it's unlikely that that is your problem. You could
try the Kilrock treatment, but it might be easier to replace the
insert(s) (if you can).

I'm going to try 'lapping' the discs on glass first. If that doesn't work
then I'll hunt for new cartridges.


Don't forget that, while the H & C inserts screw in the same
('normal') way, they turn in opposing directions. [NB: I think we
established that, otherwise, the construction is the same and, if you
prefer the handles to open in the opposite direction, you can simply
swap the inserts over.]

LOL! I discovered this after reassembling the cartridges, replacing them in
the tap, turning the tap handles off, and getting my son to turn on the
water. Although the cold tap was in the 'closed' position - it was actually
fully open - and I got drenched with the splash back! I had to remove the
cartridge again, dissassemble it again, and rotate the disc with the holes
through 45 deg. to re-establish shut off when the tap handle was in the
closed position!


I live in the Chiltern water area, and the difference is (almost
literally) chalk and cheese. The chalky water plays havoc with
plumbing - and especially taps.

Yes - I lived in Sussex for a few years and it was like that down there as
well. Kettles required 'de-furring' quite frequently and it was hard to get
a lather in the shower!
