Hive mind plumbing help, weird loo cistern

[fucthest8]

At my parents. Dad fell into it, now the fucker deposits a constant low flow into the loo, but only once it's full. When it's empty/not full, manually raising the float does not stop it filling

But what the fuck is this mechanism and where could the fault be? The fuck is the plastic sleeve around a - I think solid - plastic pipe sort of thing (not a pipe as solid, water flows down the inside of the sleeve.) What???

Any help gratefully received

The plastic sleeve is there to make filling quieter. It doesn’t splosh and drip with that.

Ah, right.

So that's all a red herring, it will be down to why lifting the float doesn't cut off the incoming flow

Then the outgoing is literally just overflow - there's nowhere else for it to go, so that's how this cistern deals with that.

That black thing that's next to the siphon, at the top right, is the float: it should move freely up and down, and actuate the valve that stops the flow. First step is to slip that up and down, and confirm that things are happening. It may have got a bit jammed as a result of the impact, and be easily freed.

Sounds like that the float valve has somehow moved so that it’s now set too high. It’s easy to adjust - have a quick Google, there’s loads of YouTube videos or text/diagram instructions depending on what you prefer.

Valve is not shutting off probably due to muck in the valve so it overflows. Try pushing the float down to let more water in to dislodge any muck and then release it.

Dad fell into it

It must be a very big cistern.

Cheers all, I know what I'm up to with the float, was confused by the plastic sleeve nonsense bit

The first time I saw one of those, I thought someone had left some packaging on it
