Whats happened is the Syphon in my cistern has become detached from the hook that the lever is connected to. But the part on the syphon has sunk into it and i cant retrieve it, can this be fixed easily?
If possible put your fingers underneath the area of the syphon that the part has sunk into. With your fingers underneath try to push the assembly up. This will only work sometimes, otherwise you will need to remove the syphon.
