A pressure flush system for use within a toilet tank includes a pressure flu sh tank having an inlet port and a discharge port, an air inlet, and a valve assembl y. The valve assembly includes a generally cylindrical housing, a water inlet in fluid communication with the pressure flush tank, a water outlet in fluid communication with the discharge port, a normally closed valve which allows fluid communication between the water inl et and water outlet when the valve is opened, a piston axially spaced from the valve, and a flexible tube positioned within the housing which is carried between the valve and the piston and in fluid communication therebetween. Relative to the valve, the piston is movable int o and out sealing engagement with the discharge port to permit the discharge of water under pressure contained within the pressure flush tank. The flexible tube is movable in response to movement of the piston.
