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 ( 60 ) to pass water lying in the tank around and above the first container, and through the coupling region and the flush valve.
