The flapper is a round rubber seal that stops water from draining from the tank and into the toilet bowl. When you flush the toilet, the chain pulls the flapper up so fresh water can fill the bowl. Problems with the flapper are among the most common causes of a running toilet.
As the tank fills, water is also sent through this tube. It is used to refill the toilet bowl since it lost its water during the flush. If this tube drops down inside the overflow tube, it can, in some instances, syphon water from the tank.
