Installed a dual flush toilet cistern outlet valve to save water
 

After much head scratching I managed to retrofit a new dual flush
outlet valve in an old cistern. This saves about 9 litres of water for
each half flush. Photos and some details at

Suggestions and corrections welcome. I usually fix computer systems,
not toilets. ;-)
