Slow refilling cistern

Postby WANOSTROCHT » Thu Feb 26, 2009 2:10 pm

I have a toilet cistern which has started to refill very slowly. The top of the cistern does not just lift off and has a central button on top which is flush with the top of the cistern, and is surrounded by a stainless steel looking ring. The question is, is how do I remove the top of the cistern to get to the gubbins inside, and then when I am inside, what should I be looking for? Thanks

Simply Build It

Generally the centre small buttons can be levered out gently which will allow access to a nylon screw which must be removed before the cover can be removed.

My guess is some debris has possibly travelled into the float assembly and blocked the valve. Dismantle the valve and examine for small bits that may be trapped. It is possible the whole mechanism may need to be removed from the cistern as many now have filters and restrictors fitted in the main body which cannot be accessed from above.

Hi there.

There was a very similar question to yours posted early in January. I have reproduced the answers here.

Posted: Sun Jan 04, 2009 1:44 pm Post subject: push button toilet

Our toilet as suddenly started re-filling extremely slowly.

I was going to take a look in the cistern to see what's going on, but have failed at even this basic first step.

The toilet has a push button flush mechanism (a single round button split into two halves for full or partial flush). This is located in the centre of the cistern lid and appears to also screw the lid down against the cistern.

Presumably the button unscrews or detaches in some way to release the lid, but it's not obvious how.

Can anyone enlighten me on how you go about taking these things apart?

Go to the DIY Projects page and look at the project on push button or European cisterns.

Depends on the make. You could try and push one half of the button down. Use a flat bladed screwdriver ad gently prise the other button up (it should pop without much force). You should see a large plastic screw under this.

Or unscrew the ring around the button and lift cistern lid off.

I hope you find this helpful.

The silver ring - unscrews - try this gently by hand.
Then look to see if the float is snagging on something.
