Abstract: A water efficient toilet includes a self pressurized tank connected to a water supply through conduits and includes a valve operatively connected to the conduits. The toilet assembly has a bowl with inner walls, the bowl having a lower reservoir connected to a trap way and an upper rim with a channel therein. The channel is provided with a plurality of openings and the lower reservoir of the bowl has through holes. The through holes of the lower reservoir and the channel of the upper rim of the bowl are connected to the valve by a first and second conduit. When flushing the toilet by opening the valve, a phased inflow of water in the toilet is induced. The phased inflow of water includes an initial and an intermediate inflow of water. The initial inflow of water passes into the first conduit and through the through holes of the lower reservoir to initiate the evacuation of the contents of the lower reservoir through the trap way into a drain pipe.
