PROBLEM TO BE SOLVED: To provide a stored liquid circulation apparatus capable of maintaining excellent liquid circulation inside a liquid storage tank without having a user or the like readjust the discharge direction of liquid into the liquid storage tank even when a liquid surface height inside the liquid storage tank varies. SOLUTION: The stored liquid circulation apparatus is provided with a controller 100, and the controller 100 controls the operation of a servo motor 40 corresponding to the water level of bathing water 3 inside a bathtub 2, which is the liquid storage tank, detected by a water level detection part 50 and executes adjustment so as to increase the discharge elevation angle of a discharge pipe 30 as the water level rises. Thus, a water stream flowing along a water surface at all times is formed corresponding to the water level inside the bathtub 2 and excellent bathing water circulation inside the bathtub 2 is maintained.
