Conversion of any commode to dual-flush is possible according to the manufacturer of the HydroRight Dual Flush Converter (and you don’t even need any tools).
So far, the word on this product is very good and the cost is around $25.00 dollars at Ace Hardware.
The video shows how it works and how to install it. http://www.youtube.com/watch?v=y-flEtWpFl4&NR=1.
