Can anyone recommend a quiet ball valve for the main water tank?, I have
seen maker names Torbeck and Fluidmaster, mentioned elsewhere.

It depends what's causing your current tank to be noisy.

If, like me, you're disturbed by the constant dribble and then drip of
water as the tank finishes filling then, yes, I'd suggest a Torbeck
valve as that worked for me(although it does give a single significant
"thump" as it shuts off which may cause a fair bit of noise if your
pipes are loose)


This can be solved with a surge arrester fitted near the valve.

Do they have an alternative name ? I've just googled that and all I
got was electrical surge protection stuff.

Sorry, I should have said Shock Arrester. These are like a small pressure
vessel that would be used on a heating system, but about the size of a fist.
There is a diaphragm inside. When the tank valve closes and there is a
resulting thump, the arrester absorbs most of the shock and reduces the
noise. You could also check that the correct flow insert has been used in
the valve. The thump is made worse if the pressure and flow rate are too
high.
