Abstract
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.
