Toilet Flushing Issue

[bape0987]

I've made a video of the problem I'm having. At first the problem was the cistern wasn't filling however I reseated the siphon which has stopped the water running into the pan. Now the issue seems to be that after a flush, the ballcock is stopping the water entering the cistern until I pull it back slightly (13s and 59s in video) which then lets the (I don't know the name of the part at the top of the ballcock) 'fall' which then lets water into the cistern. It's a relatively new toilet at 3 years old.

If anyone can help that would be much appreciated.

It's been incorrectly fitted.
The whole inlet valve needs to be turned clockwise by 10 minutes on the clock by ever so slightly undoing the plastic nut underneath the fill valve then holding the valve down low and turning it. Once turned you do it all up tight again.
Quite obviously you'll have to turn the water off and also undo the water connection into the valve too.
You can expect water to leak out when you slightly undo the plastic nut underneath.

Exactly what he said^^^^^^.
The fill valve float (the bit that drops and rises with water level) is jamming on the side of the flush valve (the other bit)

Yaaaa... Got something right at last

Really? Quite shoddy then by the builder but I imagine you're not surprised!

So would I have to turn the water off at the mains? Or would turning the water off at the isolation valve going to the cistern be fine? I'm actually here because the original original problem was water leaking from where the isolation valve meets the cistern. I replaced the broken washer with a new fibre washer and that's solved the leak. In trying to troubleshoot this, was it possible I've moved the inlet valve at all when turning the nut?

Am I turning the white nut here?

Yep it\s definitely jamming - so the fix as mentioned is by turning the whole unit clockwise slightly?

Yes, it's probably been caused by yourself.
Isolate locally then loosen slightly, twist and retighten.
Centre the float section half way between the fill valve and the cistern wall.

Yes you are. I suspect it was indeed you and thanks for being honest. Yes local isolation will be fine.
