Hi,first post here and a bit nervous about any plumbing type jobs! icon_eek.gif
We have a centre top push button toilet,just noticed that it overflows down centre pillar flush into the toilet itself,i've tried pulling up the ballcock lever but does not seem to stop the flow of water coming into the 'internal syphon' is it? Do i need to replace this and if so where can i buy one please,i have looked but really confused now! Thanks in advance. icon_wink.gif

There should be some sort of float you can adjust by turning a threaded plastic rod-hard to tell without seeing it-can you post a pic?

it will be the ballcock. If new, and it does not stop the flow when fully lifted, it may have a bit of grit or scale in it. You can take it apart and wash it out. Or fit a new one - they only cost a few pounds. A "Torbeck" valve is very quiet in use and slightly dearer. They have a delay of about 10 seconds between being fully lifted and cutting off the flow (this is part of the design).

Ok-not very clear but on the black part where you say you tried lifting the arm,there is a seperate float below it on the same post but lower-cant see from the pic but there is usually a threaded bar or it may just click down but the bottom float needs to be a bit lower to stop it overflowing,thats the best I can tell you without being there! icon_smile.gif

Read this http://www.fluidmaster.com/pdf/400uk_instructions.pdf

and make sure the float doesn't bind on the side of the cistern - also clean off the scale around the side of the float.

The valve looks like a 'fluidmaster'

Turn off th supply to the cistern and press down gentlyon the black cap at the top of the valve whilst turning a quarter anti-clockwise. The top should then come off and you can clean the valve out.

Yes,it is a fluidmaster,just got it off and found some grit in the seal at the top,gave it a good flush out and clean and now works perfectly! icon_biggrin.gif
Thanks to all of you that gave advice!
