A water storage tank built for a reverse osmosis water purifying system deploys multi water flow passages of purified water and drainage water, allocated a soft bladder unit receiving purified water encompassed by the waste water in the tank. When the water tank unit is fully filled with water, the water pressure activates the auto-shut-off valve or solenoid valve to stop operation of the reverse osmosis water purifying system. When the dispensing faucet is turned on, the drainage water swells to squeeze the soft bladder unit to deliver the purified water out from the soft bladder unit to the dispensing faucet, and the drainage water flushes the reverse osmosis membrane as well. The technique enables the tank to take the least water pressure resistance to hold water and drain water which results in energy saving and water saving. 1. A water tank unit “A” comprising:{'b': 1', '11', '111', '111', '111', '1', '1', '12', '13, 'i': a,', 'b, 'a tank having a room defined therein, multiple holes , defined through a top of the tank , the tank having an open bottom to which a bottom cover is connected;'}{'b': 2', '1', '111', '111', '111', '1, 'i': a,', 'b, 'a control valve connected to the top of the tank and having multiple water passages a-c, the water passages a-c being connected with the holes , in the top of the tank respectively, and'}{'b': 3', '11', '1', '31', '32', '32', '33', '33', '2', '11', '1', '11', '3', '1, 'a soft bladder unit located in the room of the tank and having a bladder with an axial support shaft connected therein, the axial support shaft having a connection path connected to a top thereof, the connection path connected with one of the water paths a-c, the control valve controls drainage water to enter into and to flow out from the room of the tank , when the drainage water enters into the room , the drainage water squeezes purified water in the soft bladder unit to be flown out from the tank .'}2233323111.
