Abstract
Abstract A water saver unit to be immersed in an filled with the water of a water-flush toilet system, the unit comprising a hollow body having a pair of clearance holes disposed diametrically opposite one another; a slot formed in the body and connected to and extending between said clearance holes, the slot and clearance holes providing communication between the outside and inside of the body to permit the body to be filled with water. The body being formed of flexible material so that pressure applied adjacent each said clearance hole and respectively directed toward the center of the body caused the body to distort, which distortion cause the slot to increase in width and so that when said pressure is relieved, the body will return to the non-distorted condition wherein the width of the slot is the same as before said distortion; and a weight inside of said body and being in the form of an annular member, having a central clearance aperture and a slot extending from the aperture to the periphery of the member.
