Our toilet as suddenly started re-filling extremely slowly.
I was going to take a look in the cistern to see what's going on, but have failed at even this basic first step.
The toilet has a push button flush mechanism (a single round button split into two halves for full or partial flush). This is located in the centre of the cistern lid and appears to also screw the lid down against the cistern.
Presumably the button unscrews or detaches in some way to release the lid, but it's not obvious how.
Can anyone enlighten me on how you go about taking these things apart?
