After flushing the toilet, it tends to continue to run. When it is flushed,
the flapper is pulled up which allows the water to escape from the tank,
while at the same time the float falls which opens the valve to fill the
tank with water. All is well to this point.

The problem is the flapper generally doesn't go back down to the bottom in a
timely fashion to plug the escape hole, and the source water begins to fill
the tank again.

The source water apparently causes enough turbulence that it resists the
flapper from falling to the bottom. If I were to manually stop the source
water by lifting the float, the flapper drops to the bottom. I think it
would be fixed if there were some way I could adjust the float to not allow
the source valve to open until the flapper were much closer to closing.
Yet, I've adjusted the float as far as it will go and that doesn't do it.
I also think that if it were a slower flow of incoming water, it might work.

Could it be that someone has used the wrong replacement parts? Someone has
added a 'weight' to the top of the flapper, but that doesn't really help,
and I have an objection to relying on pure Kentucky windage to fix things.

Any help appreciated.

The only thing that brings the flapper back down into the sealed
position is the water level dropping low enough to expose the flapper
above the surface of the water. Is the water escaping fast enough
to expose the flapper? The inlet water should not overcome the
emptying of the tank.

The flapper does get above the surface of the water. But the water level
never drops low enough for the flapper to close. The water level only goes
down to a height of maybe a couple of inches.

i would think the simplest solution may be to shut off your service valve,
then open it just a tad. It'll fill slower, and quieter, and the lack of
turbulance will probably solve your flapper dropping problem.

It does indeed solve the problem. But I'm pretty sure the stop valves are
not designed to restrict flow and wear out much faster when used for that
purpose.
