Ballcock vibration in toilet cistern

[richard7761]

Hi. The bottom entry, ballcock arrangement is stamped "Microvalve". It has started vibrating, but I have a fix. The water coming out of the valve and filling the cistern passes through a flimsy plastic tube. I've managed to stop the vibration by pinching this tube with a clothes peg. No idea why it has worked.

Also, there is a kind of knob (red coloured) associated it seems with that plastic outflow tube. It must have a purpose, but I cannot figure it. Just seems to dangle there. What is it for? Thanks.

No idea - I`m more familiar with a purple one

Hmm, talking of knobs...

Anyway, moving on.

Microvalve is, I think, Armitage Shanks.
Get rid and fit a Fluidmaster 400UK073, PRO400 or PRO45B.

Thanks for the recommendation. Yes, I'll probably end up buying a better quality item that can cope with low or high pressures.

Someone elses setup in the pictures, but my setup is just like you see in the pictures. You can just see the red knob thingy.

Where would I get a washer from I wonder, If I tried to replace it.

It gets better - that red knob is a spare orifice for the ballvalve in the picture . If it`s red it`s low pressure - if it`s white it`s high pressure . You sound like you need a 2/- diaphragm washer for your float/ball valve - ah well , back to the pickled onions and a nice bath.

Exactly the same thing happened to me last week with the same sort of valve and the cure was a new 29p 'rubber washer'. The old one had stiffened up and was causing the vibration.

Hi. Where did you obtain your "rubber washer" from? I cannot seem to locate the required part searching on the internet.

2/- as in "two bob"? That be 10p then.

I assume that you have undone the plastic nut so you will then have a 30mm approx formed rubber washer that seats down on the nozzle when then arm lifts. Search for "ballvalve diaphragm" on google and there are few pictures of them. I got mine from a local hardware store.

In the piccies you have linked to, end of the white plastic screw sticking out horizontally below the valve body should be snugged up against the side of the cistern, and the locknut tightened.

The screw braces the top of the valve assembly to stop the standpipe flexing and the valve chattering as the float rises.

Just checked, and that screw does press against the cistern. So, that is okay.

Damned inflation . It`s a washer for a Part 2 float ( ball) valve - that should help you locate it easier ( or is it part 3 being a plastic one ) anyway the washer is the same .
