Toilet with two flush modalities

A toilet having two flush modalities, the toilet being structured for connecting to a drain and to a source of pressurized water, the toilet comprising:

• a tank having an overflow tube;
• tank fill means connected with said tank for filling said tank with a preselected amount of water derived from a source of pressurized water;
• a bowl connected with said tank, said bowl having a trap formed therein for holding liquid, said trap having a lowest point, said bowl having a bowl outlet connected with said trap, wherein the overflow tube is connected with said bowl;
• conventional flush modality means connected with said tank for selectively delivering a first predetermined amount of water from said tank into said bowl to thereby both flush said bowl through said bowl outlet and refill said trap with water;
• and
• urinal flush modality means comprising:
• bowl valve means connected with said trap at said lowest point thereof for retaining liquid in said trap when in a closed state and for draining therethrough liquid in said trap into the drain when in an open state;
• bowl valve control means for selecting said open and closed states of said bowl valve means;
• drain connection means for connecting said bowl outlet and said bowl valve means to a drain so that water therefrom enters the drain;
• and
• auxiliary flush control means for selectively delivering a second predetermined amount of water to said bowl, wherein said second predetermined amount of water is substantially just sufficient to thereby refill said trap with water after substantially all liquid in said bowl has been drained by said bowl valve means when said bowl valve means is in said closed state;
• wherein said tank and said tank fill means collectively provide a source of said first predetermined amount of water.
