Forgive me if these questions are daft, I know next to nothing about plumbing.
I've got an issue where my cistern doesn't fill and water just constantly runs in to the bowl. I think it might be the outlet as I pushed down the internal plunger/washer thingie on it just now and it filled again. So I'm either going to replace the unit or the washer on it and hope that does the trick. Is that what I should do or could it be something else too?
The other question I have is about the filing valve. When you flush the water seems to come out of the white tube at the top, is it supposed to do that? I thought it filled from the bottom?
Also, is that white tube supposed to be in the little hole in the overflow? Because it was just hanging loose outside as seen.
Thanks for any help.
