ABSTRACT:
A toilet tank capable of use in combination with a toilet or commode to allow improved flushing operations. The toilet tank comprises a smooth inner surface and a formed bottom portion defining a tank evacuation hole at a base of the conical portion. A flush ball head will seat into a sealed position over the tank evacuation hole, guided by the tank walls. The flush ball may be weighted while the remaining, generally tubular flusher element may be left hollow to facilitate a generally vertical orientation of the entire flusher.
