PURPOSE: A dual water level adjusting apparatus for a water purifier is provided to simplify the design and the structure of the apparatus and overcome the limitation of an installing space. CONSTITUTION: A dual water level adjusting apparatus for a water purifier includes a filtering filter, a storing tank, a raw water stopping valve, and ball tops(160). Filtered purified water is supplied into the storing tank through an introducing conduit. The ball tops include a buoyancy(161), a shaft(163), a body(165), an electromagnetic switch(167), and a mechanical valve(169). The buoyancy vertically moves according to the water level of the storing tank. One end of the shaft is fixed to the buoyancy. The body is supported on the upper side of the storing tank. Another end of the shaft is fixed to the body. The electromagnetic switch is operated by the axial-rotation of the shaft and opens and closes the raw water stopping valve. The mechanical valve is inserted into the body.
