A shower head operates under low water pressure. The shower head utilizes a unitary ball. The ball includes a vaned member integrally formed in a passageway through the ball. The vaned member includes a plurality of spaced apart helical arms coterminating at an intermediate rounded spherically shaped surface which evenly distributes water intermediate the helical arms. Water from the vaned member discharges into a large vortex chamber and from the vortex chamber through a smaller venturi-like aperture which accelerates the water past aeration ports.
