ABSTRACT:
A water saver toilet that produces a larger water spot (122) in the toilet bowl (12) and a better flushing, and that enables partial and full flushing. A trapway (14) that extends from the toilet bowl outlet to a drain (16), has upper and lower traps (30, 32) and a trapway passage (34) that extends between and into the traps. The lower trap is constructed to be sealed by water therein prior to each flushing, and a pressured air source (98) applies pressured air to the trapway prior to a flushing. The pressured air in the trapway pushes some upper trap water into the toilet bowl to increase the water spot therein. A first container (40) lies in the water tank, and the water therein can be flushed down from the first container though a coupling region (80) and though a flush valve (24), for a partial flushing. A full flushing is achieved by opening a second valve (62) to pass water lying in the tank around and above the first container, and through the coupling region and the flush valve.
