Watch where the water comes out and goes into the bowl. There are about 50 or so holes to allow that water to flush. If they are restricted, it will impede the flow. Take an ice pick or nail and poke each one of the holes. If you feel any that are blocked, that may be your problem.

The flush started leaking into the bowl and after sometime it stopped flushing. I closed the main valve to save water, but now I need to fix it.
I cannot open the lid as the flush button seems attached. Any help here is appreciated. Find the photos attached.The cable attached to the button may be clogged. There is an excellent article with pictures on all kinds of problems with this type of toilet here: www.diydoctor.org.uk/
After a water main break down the street, the toilet makes a loud, rumbling noise each time it re-fills. Is there an easy do-it-yourself fix?
