How to Install Fluidmaster's 550DFRK Duo Flush System

The Fluidmaster 550DFRK Duo Flush System will help you save more water than any other dual flush system on the market. The Dual Flush System retrofits into any 2” 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. It comes complete with a high refill fill valve to insure consistent flushes every single time. A dual flush tank lever is included with this system.
