Toilet bowl fills after flush

[mjb0871]

Hi
Our toilet bowl is constantly filling after flushing.
I've looked on the internet and youtube and couldn't see anything like the cistern we have (I'm no DIYer by any means)
I've attached a picture, cousl anybody point me in the right direction? I've tried to change the height of the white floaty thing (technical name) that changes the water height, but nothing changes.
Cheers
Mark

The white floaty thing is letting water through. Either needs a cleaned/ washers replaced.

I think you are refering to your toilet pan ...thats the thing you sit on...the pan
or are you refering to the white box of water that sits behind and above the pan ?
if it is the cistern not the toilet bowl then its easier. Maybe the floaty thing has failed
. look underneath for a chrome valve with a flat screwdriver slot. Turn it by 90deg
this will turn the water off ....then get back to us. centralheatking

See I said I was no expert!

The toilet pan/bowl is getting a constant trickle of water from the cistern (the box on top on the toliet!)
I adjusted the white floaty thing so it sat lower in the water, thinking there would be less water in the cistern and then it wouldn't overflow...I was wrong because I guess the water goes from there to the bowl at a lower level.

If you gently but firmly pull the white float cap up does that stop the water filling the cistern? I find adjusting those floats takes time to find the sweet spot, a little bit out either way and they don`t seem to shut off the water.

no it doesn’t. Doesn’t even slow down.

Get it replaced with a quality unit, with a brass thread. Quick, easy, peace of mind.

Probably best to replace it in all honesty. If you can isolate the water to the fill valve we can talk you through it.
