Fluidmaster has a kit that adapts a standard toilet that uses a 2" flush valve with flapper, into a dual flush toilet. You can dial down the amount of water used for the two flushes, keeping the larger flush for big items and a smaller flush for liquids.
Most hardware stores carry them. If you make the change, you should really pick up the entire kit that comes with the adjustable fill valve to prevent overfilling of the bowl.
I was wondering about using other brand fill valves, but the port is sized to only work with the Fluidmaster hose.
The piston at the bottom used a clear seal.
The flapper is removed, and the new fill valve is installed.
Here it is with the adapter snapped over the overflow, which will now take the DuoFlush unit. It will snap right over it.
The trip lever operates on a cable. Down for large, Up for small.
