I#ve recently re-washered the H & C taps on the
bathroom handbasin.

Now, both washers were from the same batch, but
whereas that on the cold tap remains soft (and
requiring more and more turns to shut it off),
that on the hot tap has gone hard and seems to
be dripping again unless screwed down hard.

I suspect that the hot tap needs reseating,
but it there any explanation for the differing
performance between the H & C?

Could also be bad design of the washer, gets ****ed by hot water.

In the old old days hot and cold washers used a different rubber, the
hot being more temperature resistant (often two colours, as well). I
have not seen this for decades, they are normally made from the same
sort of synthetic rubber that should not harden in normal hot water. Is
yours *very* hot? If so, it's potentially unsafe. I suspect you have
just got cheap and very unsatisfactory washers.

Are the taps very old? I have re-cut seats on old valves a couple of
times, but it's not a common problem.
