Abstract
A pressure flushing system for use within a toilet tank includes a pressure tank which has a predetermined volume. There is a water outlet for the tank, a water inlet for the tank, and an air inlet for the tank. The air inlet is associated with the water inlet whereby water flowing into the tank draws air into the tank. A portion of the tank is thus occupied by water and a portion is occupied by air, with the air applying pressure to the water. There is a valve within the tank which controls the flow of water from the tank through the outlet. The volume of water within the tank which may flow through the outlet at any one operation of the valve is limited by a dam which is located within the tank and surrounds the outlet.
