Abstract
A pressure assisted dual flush operating system includes a vessel for receiving, containing and discharging pressurized water and an outlet for discharge of water from said vessel. An anti-siphon valve includes an air inlet for introducing water into said vessel and an inlet valve is provided for admitting water to the anti-siphon valve. A dual flush valve selectively releases different quantities of water from said vessel through the vessel outlet and a control valve selects one of the different quantities of water released by the dual flush valve.
