Water doesn't fill under cistern lid

Be careful pal , you / she maybe better with a plumber or YOU may burn yer bridges with your
“lady friend “

 

[Riley]

All women are better off with a plumber

 

[Ben-gee]

Just make sure she’s out when the plumber comes around two reasons
(i) most of us are irresistible
(ii) you can pretend you did it!

Right so there's been a development. I can't get the green lid off. I don't even know how it comes off. But I flushed it again, by the same process of filling it up with shower water, but this time I watched the water get syphoned out and there's a lot of white residue when it's completely empty. It looks and feels like wet ravioli, but white. Is there any chance removing some of this will fix the problem?

 

[Riley]

No no the whole part not just the lid. You will need to remove the toilet cistern and remove the siphon from underneath

 

[Riley]

The residue will have no impact. The siphon is goosed

Sorry misread your first response.

I suppose that's that then. Why does it work when there's more water added to it though, out of curiosity?

 

[Riley]

Less distance for the water to travel up to create the siphonic action. The diaphragm may not be completely shredded and can pull a little water up with it when you pul the flush handle

To remove that syphon you first have to remove the entire cistern (if it is tight down to pan - ‘close coupled’ type).
That means turning water off and disconnecting the nut below cistern to the fill valve and also nut to overflow.
Then under the pan at cistern you have 2 wing nuts to remove which often are rusted solid.
Also screws holding cistern to wall need removed and often idiots use rusting steel screws, so that is fun.
With cistern off, you can remove syphon large nut below and remove syphon. New syphon might not suit the length of wire link to handle, so beware.
You need new dome rubber washer between pan & cistern and perhaps washer for to fill valve (from copper pipe).
Risks are you could break the cistern, or leave leaks.
And customers often say it is just a wee job.
Personally I would advise getting a plumber.
Look after your lady in ways you are expert in.
