ABSTRACT:
A water tank for a flushing system comprising two control knobs for two-step flow control, wherein the valve cap of the drain valve in the water tank is opened for completely draining all of the water out of the water tank when a first control knob is rotated. The valve cap of the drain valve in the water tank is opened and a float is released from the restraint of a rocker arm when a second control knob is rotated. The valve cap of the drain valve is then forced to close by the released float, after half the volume of the water has been discharged from the water tank.
