A flush control mechanism for a toilet tank includes a pivotable control element which is pivotable about a generally horizontal axis in the tank, a trip lever mechanism, a fill water valve element which is connected to both the pivotable control element and the main water supply pipe which extends into the toilet tank, and an adjustable valve element. The pivotable control element includes a weightbox which is divided by a baffle into a water inlet chamber and a water outlet chamber, the floor of the weightbox including a drain hole which communicates with the water outlet chamber. The fill water valve element includes a primary nozzle for discharging fresh water directly into the toilet tank and a secondary nozzle for discharging fresh water into the water inlet chamber of the pivotable control valve element, as well as a control arm which is connected to the end of the pivotable control valve element. The adjustable valve element is employed to adjust the flow of fresh refill water which flows from the secondary nozzle of the fill water valve element to the water inlet chamber of the weightbox.
