Used in commercial venues, flushometers enable efficient, high-pressure flushing for tankless toilets. They include the handle as well as a mechanism (often concealed behind a wall) housing low and high-pressure chambers with a piston or diaphragm between the two. The flushing action equalizes the pressure and allows incoming flow from the water supply. Flushometers are used on urinals and toilets. Options include push button, touch-free sensor flushing, and eco-friendly modelsusing a turbine powered by water flow.
