Why does my toilet flapper not stay up?
The problem is caused by too much slack in the lifting chain that connects the flush lever to the flapper. When the chain has too much slack, it cannot lift the flapper high enough to allow the full amount of water to flow down through the flush valve; it closes prematurely, stopping the flush.

Where does the water go when the toilet is running?
When the water escapes through the flush valve, the float cup drops down, which causes the supply valve to be opened, and freshwater begins to enter. The majority of this water is used to refill the tank, with the remainder going into the toilet bowl via the refill and overflow tubes. The water supply shuts off.
