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 cock 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 cock fitted by the plumber so I don't get that
psst....psst...psst.... sound as the water slops back and forth in the
tank.

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.





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.
