It CAN'T be the donut otherwise as with the pipe it would be all over
the floor, even then it would have to get past the flapper to even
leak! If there's no water on the floor the only thing it can be is the
flapper. 5$ fix from any borg. Think about it, the only thing the
donut does is seal the bowl to the tank, that flapper is above that
holding the water back in the tank.

Sure fire test is to wait til the tank is full and the water fill
shuts off, put some food coloring in the tank, if the bowl water
changes color you've got a leaky flapper.




Or a bad flapper seat.They get crudded up or rot,also.
