6. A toilet comprising:
a toilet bowl; and
a tank system attached to the toilet bowl, the tank system comprises:
a gravity tank configured to contain water at atmospheric pressure;
a rigid pressurized tank positioned within the gravity tank and configured to contain water at a pressure greater than atmospheric pressure;
a piston assembly positioned below the rigid pressurized tank and configured to open and close the rigid pressurized tank, wherein the gravity tank is configured to channel water at atmospheric pressure into the toilet bowl at a first velocity and the rigid pressurized tank is configured to channel water at the pressure greater than atmospheric pressure into the toilet bowl at a second velocity, and wherein the second velocity is greater than the first velocity;
an outlet valve positioned below the piston assembly and configured to selectively channel water from the gravity tank and the pressurized tank into the toilet bowl; and
a solenoid valve positioned within the gravity tank and configured to selectively channel water from the pressurized tank into the piston assembly.
