The tank is the business end of the toilet. It all starts in there. The water is stored in the tank until the handle is tripped. The handle opens the flapper valve, allowing the water to flow into the bowl. As it leaves the bowl, the water splits and goes to the water siphon jet hole and to the holes under the rim.
The waste water exits the bowl through the colon and through a passageway before leaving the toilet. That concludes Toilet 101. Tim's flushed with excitement!
