We have a close-coupled toilet cistern in our utility room which leaks. It
doesn't leak externally, just into the bowl - the cistern overfills and
water leaks into the bowl via the overflow. This is of a modern type that I
have had no dealings with. It is of the type that fills from the bottom with
a vertical column that has a float attached. These can be replaced entirely
for about £15, but as this one is only about 2 years old I was wondering if
it is possible to strip these down and replace the washers? Any advice would
be greatly appreciated.
I have one of those and after it had been in use for a while, it may have
been about two years. I had to adjust the angle of the float to stop it
overflowing. Its been no trouble at all for the past two years or so. I put
it down to the washer bedding in.
Have a look at the float arm where it presses the valve. Mine has a threaded
adjuster, just lengthen the screw thereby pushing the float deeper into the
water, it might be all it needs.

I also reached the conclusion at the time that it was probably easier
just to get a full replacement if that didn't work as the frustration
level/time outweighed the cost for me.
Reading about vaseline prompted me to mention that my cistern became
hard to operate (flush button need a hard press) and I thought 'that's
strange - it's all plastic. What could have happened?' So I oiled the
flush mechanism with engine oil and it's fine now.
