Any toilet experts out there?

Having problem with one of the toilets in my house. It is the type whereby there is a button on the top of the toilet and you press down to flush. Problem occurs after flushing whereby somewhere in the toilet continues to trickle water a few minutes after the flush and dosn't appear to stop! It's more anyoying than anything else. Didn't do it before and the other 2 toilets in the house are fine. I have tried to remove the cover to see inside, but can't seem to remove it! No water leakage out or anything like that.

Can anyone offer any help?

Many thanks.

Push button should unscrew in cistern lid allowing access to inside.
Alter flow of water into cistern by adjusting float
Push button toilets have internal overflows which is the trickling problem
you are having. Cistern not fully closing off water . If altering float does not cure go to DIY store ask for UNIVERSAL SYPHON PACK with internal overflow.
Just turn water off and drain cistern by flushing .Simple unscrew and replace
with new .
Hope this helps but 99 out of 100 float movement will fix problem !!

Will have to pass this info on to my other half for him to sort out. Or get the plumbers in from the site to look at it (it's a new build home). Too technical for me! Thanks for the tip Barney666 :A

If it's a new build home, get the builder to fix it if it's less than 2 years old (I think it's 2 years with NHBC for everyday defects??, maybe it's only 12 months)

we had a similar problem when the toilet was fitted into our loft conversion, turned out there was a type of cable contraption (similar to bicycle brake cable) which wasnt releasing thefore wasnt shutting off properly.

plumber replaced with a new cable thingy, every thing ok

I know it's the best and cheapest option to get the builders to sort out (only been in house 2 months), but me and partner both work 9-5 so never see them unless we're on holiday! Just wondering if there was a possible quick fix.

Take the top of the cistern and have a look.
The ball float valve can be adjusted.

Not on this type of flush it can't. There isn't one.

There is a float device, but adjusting it won't make any difference to the problem they're describing.

I can only think that the plunger on the bottom of the flush button is set too low and is stopping the flush mechanism, which is returned to the top by a compressed spring, from rising fully up to it's rest position.

Remove the cistern lid and there should be a 'piston' type plunger screwed into the underside of the button. Try winding it in half a turn at a time and put the lid back. Flush and see if that solves the problem.

Ah right, I've never looked at one of these. I still advise taking a look because it might be obvious when you see it.

The inlet valve is probably a Fluidmaster float valve and it's not necessarily overflowing. Modern push-button toilets have a drop valve as opposed to a syphon and they have a diaphragm that is seated on the bottom of the cistern that is lifted to allow a flush. Quite often these are faulty and let a trickle of water past and need replacing. In the case of a back-to-wall low level pan the problem is often that the flushpipe has not been cut to the correct length and is pushing the diaphragm up.

Why did they go over to drop valves from syphons then? Something to do with water saving?
