Toilet has stopped working

Zither

Hello,

Could anyone help? Something's gone a little bit wrong with my toilet. It's taking a long time to re-fill after flushing and I think it's to do with the inlet valve on the right hand side (see pic related) - when it's refilling its making a hissing sound from the top of inlet - I think either because its possibly blocked or because its leaking.

Does anyone know what might be wrong with it/how to fix? Or, where I can buy a replacement - are these parts universal?

There's a brandname on the component in the middle - 'Macdee AFV50100'.

(Haha this is the first time I've looked in the cistern - didn't realise it was so dirty! )

Thanks!

Taking a very long time to fill is normally caused (odd as it may sound) by a tiny split in the rubber diaphragm in the filling valve.

It will be something like this but there are several different makes

This is one of the most popular.

You often have to look quite hard to find the really tiny split! At a quick glance they can look fine even though they are not.

It is inside the white plastic knurled nut.

Thanks! Is the link still not working? I had to reset it .

If the pic is now working, which part is the filling valve, please? Are the valves universal?

Thanks!

Ah sorry, I've just re-read your last line.

Is it easy enough to get off and do myself?

Is the white plastic nut the one at the top, on its side? Will the diaphragm you linked me to fit this one?

Had same problem on our loo few weeks back....screwfix do 2 diaphragm washers from £1.49 or £4.45
Its hard to see but you will have a fine hole or split in the old one also an easy fix once you've turned water off...5 min job

https://www.screwfix.com/p/arctic-products-siamp-diaphragm-washer/5006j
this is the more expensive one

Take the old one out to make sure you get right one

Yes, if you are reasonably used to doing that sort of thing.

Obviously you need to turn the water off cistern then see if you can carefully unscrew the knurled nut and remove the diaphragm. You need to get exactly the right one.

Sometimes the whole assembly can be fairly cruded up with hard water deposits etc and they can become brittle with age so take care. At the moment it is borderline usable, if you crack it getting it apart then it wont be!

You can also get a complete replacement filling valve for £7 to £10 but that means making watertight plumbing connections. Again easy enough if you are used to doing it.

There will be some videos on Youtube showing how to replace the diaphragm on popular makes.

Indeed!

On the one I linked, there is a small plastic pin through a white grommet on the diaphragm (forward of the bigger bit of plastic in the centre). For some cisterns you have remove that small plastic pin before fitting as the valve has a fixed pin that goes through the same hole.

Ah excellent, thanks - probably best to turn the water off at the cistern (I think there's a filling valve nut underneath the cistern) and unscrew the nut and have a look inside to buy the correct one?

Ah thanks - I don't really want to get a plumber in (£££) if I can have a go at doing it myself

Sorry to say but you won't get a replacement diaphragm washer for that at screwfix, the easiest way to replace the fillvalve but that will mean turning the water off & removing the old one, if you aren't confident & you don't know anyone that can help then phone a plumber

Yes but also read the bit I added in post #6!

Good info thanks - if I need to remove mine I guess it will be obvious if I need one with a pin or not?
