Main Water Tank: - Noisy Ball Valve

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

Sometimes I sits and thinks, other times I just sits.

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)

Cheers,

John

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.

Thanks for that. I may install one of those if things get noisy (currently the thump is akin to the noise you'd get shutting a kitchen cabinet door, you can hear that it's happened but it's not deafening or anything)

Cheers,

John

I've got a torbeck in the toilet systern (bottom entry) and a fluidmaster in the hot water header tank. Both work well. The torbeck is silent but I don't think it would have enough flow for the hot water, (perhaps they make bigger ones). When I fitted a new bathroom suite I transferred it to the new systern rather than fit the ball c*ck that was supplied. I've got a spare diaphragm for it (somewhere) but I've never needed it.

The fluidmaster is easy to fit and doesn't flex the side of the tank like the Victorian ball c*ck fitted by the plumber so I don't get that psst....psst...psst.... sound as the water slops back and forth in the tank.

I have a good solution that addresses both issues - i.e. quietness and getting enough flow for the tank in the loft.

I fitted two Torbeck valves to the tank. This gives plenty of flow into the tank as follows:

- One valve is set to operate on/off at a higher level than the other. This higher one is fitted with the high pressure restrictor as recommended by the manufacturer. This is to prevent water hammer and to ensure correct operation of the mechanism.

- The second valve is set to open lower and is fitted with low pressure restrictor. However, this one opens second and closes first as the level rises. There is plenty of flow through it and when it closes, no thump because the first valve is still open.

- For small amounts of water drawn off, only the first valve opens. For larger amounts the second one does as well.

It works very effectively and Torbeck valves are very inexpensive so two is not a major investment.

I have done the same with Fluidmaster valves. However, in general I have not found them to be as reliable as the Torbeck. A typical problem is that the float seems to stick, so I threw mine out.
