I have bought a Fluidmaster bottom entry valve but it is too tall to fit my
cistern, unless I leave the lid off!. If I adjust the height down, the
"Critical Line" mark falls below my internal overflow. The instructions say
it is supposed to be at least an inch above - so the Fluidmaster is out!
Are there any other models that do not need quite so much height?
Unfortunately I have to find something suitably quiet, SWMBO is insisting
ever since she heard her friends loo or should that be didn't hear her
B&Q usually have them. I think Focus might as well, and plumber's
merchants certainly do.
Here is the Screwfix detail for what you are looking for.
Obviously check the dimensions before buying.
There is a diagram at
Level adjustment is done by rotating the float so it travels up and
down in the arm.
If you are tight for space and the stalk of the float fouls the
cistern lid, after adjusting you can clip off the excess.
You do need to pick the right flow restrictor when installing.
It wouldn't hurt to use a new fibre washer as well.
The usual note about being careful when putting the back nut of the
tap connector onto the fitting definately apply to this like all
plastic ball valve fittings. A useful trick is to leave the nut
fixing the valve in place in the bottom of the cistern loose, then
locate the brass nut on the thread of the valve and tighten both.
This is much less likely to cross thread.

Well I have fitted a Torbeck. I phoned my local water authority to check my
mains pressure to decide which size reducer to use, I was just inside the
band for the high pressure reducer so i fitted it. however filling the
cistern went from 40 seconds to more than 3 minutes! So I changed to the low
pressure reducer it now takes 85 seconds - does this seem acceptable? it's
noticably slower than the old one, should I try it with no flow restrictors
even though the instructions say not to for mains pressure?
On the positive side it is very quiet which is what the wife wanted, maybe
we just have to trade the slower filling times?
I fitted a Torbeck a while ago, after a long hard day when everything
went wrong (stopcock wouldn't work, old ball valve stuck, no service
I forgot the flow restrictor, and it filled a little faster than before.
No sign of leaks, overflow etc....! I was tired, so I left it...it's

Funny how you wait ages for a subject to come up in a thread and then all of
a sudden 2 or 3 come along at once :-) Something similar came up recently in
the thread "Cold Water Tank Valve".
If you just want a quiet fill from a standard WC cistern float
valve you can hang a bit of plastic pipe e.g. overflow pipe over the outlet
of the valve so the water runs down inside the pipe without splashing. You
must make sure there is NOT an airtight connection between your bit of pipe
and the outlet of the valve (so water couldn't get sucked back up the pipe
and into the valve and thereby the water supply if there were a partial
vacuum in the main supply pipe - water regulations).
All Torbecks have is a bit of polythene tube - like an open-ended plastic
bag about 20mm wide - down which the water flows. I occasionally come across
quite ancient brass piston valves with plastic tubes fitted to the outlets
for quiet filling, so the idea's not new.

Well it will cure the splashing but not the singing which is the main
source of noise in a standard ballcock valve. Torbecks (really just a
particular make rather than a type) are not only quieter than a normal
ball valve but also faster. Note the warning on the packaging about
ensuring the overflow can cope, a torbeck type valve lets in water
quicker than a normal valve.
They have a different operation principle as well and are far less
prone to singing. The difference is more than just 6" of soft poly
