Gravity-Flush System

A Gravity-Flush System uses the natural weight of the water in the tank to generate enough pressure to flush a toilet. The water pressure forces the water from the tank down into the toiletbowl, then through the S-shaped trapway. A siphoning action completes the flush. This flushing system is quieter than the pressure-assisted system, simple, and requires less maintenance than other, more complex flushing systems, but can clog up.
