A dual flush volume pressurized flush device. A pressurized tank includes a tray for controllably retaining water during a flush event. The tray retains a certain volume of water when a reduced flush is activated, such that the entire volume of the tank is not flushed. In a full flush event, the activation causes substantially the entire volume of the tank to be flushed, including the volume of water inside the tray. A controllable water retention tray valve is positioned in the tray and provides a controllable release for the water in the tray.

What is claimed is: 1. A dual flush system comprising:a pressure flushing tank having an inlet and an outlet;a retention tray adapted to be disposed within the pressure flushing tank, the retention tray having a housing comprising a bottom portion, a sidewall, and a central opening located in the bottom portion with a column rising therefrom and forming a wall, the retention tray being open to the pressure flushing tank at a top portion, the housing defining a volume;a flush valve for controlling the outlet, the flush valve disposed within the central opening;a retention tray valve disposed in the retention tray, the retention tray valve providing a controllable opening through the housing; andthe retention tray valve further having a valve seal engagable with a valve seat disposed in the housing and further engagable with a valve stem for manipulating the position of the valve seal in relation to the valve seat,wherein frictional forces between the valve seal and the valve seat retain the retention tray valve in a closed position when the pressure flushing tank is filled.
