Ideal Standard toilet not refilling

[nimjim]

Hi all. This forum recently helped me replace a lock for the first time, now I'm hoping to turn my hand to a bit of plumbing. The joys of buying your first house!

The toilet flushes fine, but frequently fails to fill up again. If I fiddle about with the part circled in the photo it'll fill up again. It seems to be getting stuck after the flush, is it easy to detach so I can try giving it a clean? Or does the whole flush system need replacing? Thanks

Are you sure it’s not filling up, or is it a delayed fill as some Ideal Standards are designed this way

I hadn't heard of that before. So it only tops up the cistern when it needs to, rather than after every flush?

It's the fill valve that's defective; not the flush valve.

Yes it's definitely the fill valve (I now know what it's called, thanks!) I just did a couple of flushes until it wouldn't flush any more, and it didn't refill.

Does the whole valve need to be replaced, or can I take out the part I've circled and clean/replace it?

No, it fills after every flush, but some have a slight delay, iirc it’s only about 3 seconds

Ah OK gotcha. Yes the downstairs loo has that short delay, but the one I have the problem with sometimes doesn't fill up at all

Fit a complete ,new float valve. Preferably one with a brass tail.

So I've fixed it following advice from a neighbour......I've put a 2p piece on the fill valve which seems to be just enough weight. It has been filling up without fail for the past week. Just a temporary fix for now but it has done the job
