A water closet tank discharge regulating means comprising;

• (a) a minitank unit whereby the tank is divided into water retaining compartments;
• a first compartment and a second compartment,
• (b) a port in the minitank unit through which water may pass between the first compartment and the second compartment,
• (c) a valve which serves to seal and open the port,
• (d) an actuator linking unit by means of which the valve is operably connected to an existing flush arm of the tank, and
• (e) an adjustment means which is employable to set the degree of rotation of the flush arm needed for a valve opening, and wherein the minitank unit, the actuator linking unit, and the adjustment means are installable in the tank without modifying or significantly disturbing the existing in-tank mechanisms and the installation of the discharge regulating means requires no specialized tools and no specialized skills, and wherein the adjustment means comprises:
• (1) an adjustment arm which is pivotably mounted to a vertical wall of the minitank and the adjustment arm is provided with a series of attachment locations spaced along the length of the adjustment arm,
• (2) a connector linkage which is joined at one end to a suitable actuator linkage and which is joined at the other end to an appropriate attachment means along the adjustment arm, and
• (3) the adjustment arm has a cord connected to one of the attachment means and the cord serves to operably join the adjustment arm to the valve.
