The Fluidmaster Duo Flush gives you a tool to help save more water than any other Dual-flush system on the market. The Dual-flush system retrofits into any 2 in toilet tank and is proven to use up to 45% less water than the original tank parts. It also has been shown to improve flushing power on the full flush, so you will actually see better performance than before. A Dual-flush tank lever is included with this system.
