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?

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.

You were clear enough, I was just trying to add some more info. I guess
in the old days that natural rubber (or the synthetic SBR which is
chemically almost identical) might have been used for cold tap washers
for cheapness. But the other common synthetics such as nitrile, butyl,
EPDM and neoprene which have a higher temperature rating are (IIRC) not
significantly more expensive these days. I think they would all be safe
for potable water. Silicone and Viton will take higher temperatures and
are a bit more expensive. In a tap washer, the environmental factors
that degrade some rubbers (Ozone and UV light) are not present. On a
quick Google I have not been able to find any obvious statement of what
tap washers contain.

When I was a kid in the 1950's/60's tap washer replacement was if not an
annual then certainly a routine job for my dad. I don't believe I have
replaced more than three or four in my ten or so taps in the past 30 years.

Yeah some of mine are very hard something or other.

I never had anything like that and it would have been me doing it.

taps in the past 30 years.

Me too in the 45 years in this house I built.

And more in the laundry taps than the kitchen taps
for some reason and they are all the same technology.
No cartridge taps at all for me.

Rubber washers have a high temperature coefficient of expansion, so what
might be shut off when hot may not be when cold.

The other problem I have come across it the tap thread, where it becomes
stiff when under pressure. I would suggest an application of silicone
grease on the threads to see if this helps.

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

About 7 years ago I replaced two taps. The cold one always did this, and
early this year I took it apart and discovered that the seat was simply
not uniform - maybe a casting error - so it would drip unless screwed
down HARD which of course destroyed the washer.

I spent hours reseating it because I couldn't get a decent replacement
in the same style.

Fredxx explained :

might be shut off when hot may not be when cold.

The metalwork of the tap will also expand and contract with variations
in temperature. When washing up, I will set the cold tap to dribble to
rinse things. The slow dribble will sometimes stop when the really cold
water gets to the tap.

Not been a problem, especially with the Torbeck

Tirning the tap more just ends up deforming the washer into the seating.
The washer is just like a lid - pressed "on" should be enough. Tightening
it more only ends up wrecking the washer and wearing the threads.
I used to orient the "H" and "C" into the correct angle when the tap was
turned off sufficietly. I could tell at a glance when my brother in law had
been round as his house wasn't well maintained and he was used to being
brutal with taps.

Yep, me too. Some see the spout dripping after it's off, as a need to
give it an extra 1/2 turn, whereas it is just the spout draining. The
cold usually does this, as the cold water warms up and expands.
