Yes indeed, one that goes underwater is the way to go. I need one for my
toilet cistern as well as it has the wrong valve size, ie its for a mains
feed not a gravity feed and so it constantly sounds like a babbling brook.

While tying up the plastic ballcock arm in the loft, I rather stupidly
snapped it. I went out and got a brass one, which seems to be a much
stronger replacement, so no big deal. However, the new one is a lot
noisier than the old one. Again, that wouldn't be a big deal, but when
the tank is close to its full level, and the valve is near to closing, the
noise starts to fluctuate. I imagine that it has created some kind of
resonance in the water, and that adjusting the mains water cock will get
rid of it (I only open it about a single turn). But I have a question
about the new brass valve. The water comes out of a hole drilled into the
bottom of the valve body. Okay, I know it's got to come out of somewhere,
but since it just dribbles and splashes all over the place, I'm wondering
if perhaps there shouldn't at least be some kind of nozzle to attempt to
direct it (like the old plastic one had)? Am I supposed to buy something
else to finish it off? I'm thinking that this might be contributing to
the noise.
