Abstract: A method and device for limiting upward movement of a flapper valve in a toilet having an overflow pipe, wherein upon flushing the toilet the flapper valve is raised to a maximum height. The device comprises a spherical body having a bore therethrough with a diameter slightly less than the diameter of the overflow pipe. The method comprises inserting the spherical body onto the overflow pipe and positioning it at a height on the overflow pipe such that upon flushing the toilet, the flapper valve is raised and contacts the spherical body, which prevents the flapper valve from being raised to its maximum height. The device limits the amount of water used with each flush and prevents the flapper valve from becoming stuck in an upright position.
