Toilet keeps running and water flows into pan

[Dougie212]

Hi there

I have a toilet that won’t stop filling and results in the water running out into the pan - like it’s constantly flushing.

I seem to remember having a problem like this before on another toilet and it was the flush valve - I think.

Could anyone tell me if this is the likely cause and if so, from the pictures could you tell me which flush valve it is I need please

Thankyou!!

Is the float on the flush valve assembly stuck, or does it need its position changing so the water stops before the overflow pipe?

If the water level is reaching the overflow level ,the issue is the float valve.
If it doesn't reach ,it's the flush valve.
Which is it ?

Thanks both for your replies. It’s reaching the overflow. I’ve turned the adjuster on the float but that doesn’t make any change.

Fit a complete new float valve .

Will do… thanks for your help. Do you know from the pics what float valve is currently in there so I can get like for like please?

Why do you want another the same as the one that's let you down ?
Fit a fluid master with brass shank instead.
