cistern won't stop filling

[jomcroon]

hi

the cistern when flushed fills up as normal but continues to fill, and overflows via the pipe in the middle of the cistern into the toilet/pan i've taken a picture and would appreciate advice on how to fix it and or identify what type it is as I've tried googling it and there seems so many diff ones- and this is gonna sound so strange- the only way to stop it filling is to turn the wash basin tap (next to it) on for a few seconds and this stops it!

thanks

We are gonna need some better photos, preferably showing the bits in the cistern side on with the cistern empty (if possible)

thanks will try again after work but i doubt it as the whole thing is only accessible from the top and i don't want to try an take it out until i know more about it as i'd prob make a hames of putting it back in again

regards

hi
tried again to photo but no chance as i can only look down into it- tried from side but no space and dark
thanks

You could try replacing the fill valve, it looks like a side entry so if you can turn the water off it's fairly straight forward to replace, a fluidmaster should fit ok.

although the brass shank is better if you can get one.

the first thing i would do is adjust the float/ fill closer by turning the screw on the top

ta, i tried that a little, left turn to reduce level?

By opening the cold water tap you reduce the pressure on the cistern valve so don`t see how adjusting the water level will accomplish anything.

Looks like a fluidmaster inlet valve. Get a new diaphragm washer for it from b and q for about three quid.

Fill valve could be anything, it would be a lot safer just to change the whole thing as the OP does not sound to confident on diy.

thank you apologies late reply, i think changing whole thing is easier for me, i've just managed today to get the company to send me spec for the actual flushing valve/mechanism, it only took 3 weeks, earlier they just sent me how to fix it to the wall! so i'll have a look at that over the weekend
keep you posted
cheers
