Push button toilet keeps running

[Atif Malik]

I have checked the seal of the flush valve unit having watch a number of youtube videos and its fine, but what the videos dont cover is, the water stops running when i detach the push button box that links with the valve to the push button. Only when i detach that does the water stop running so does that not mean there is a fault in the box and it doesnt seem to reset unless i take it off - ie the spring or somehting is worn?

A common problem usual a new flush valve is the best way. Kop
