First of all, where's the short rubber or plastic tube from the valve
body to the overflow drain tube?

Second, the screw on the valve end of the float lever is probably the
adjustment; turn it IN a 1/4 turn and see if that solves the problem.

Otherwise, the "seal" or washer inside the inlet valve ought to be
replaced. $2 +/- at local hardware.
Turn the water OFF.
Remove the little locking tang from valve body, twist the top of the
valve OFF. The rubber seal is before you.

Good pictures!


It has never had the rubber tube and there has been no problem until
recently. No water ever runs out of that opening when the toilet is
flushed, so I don't see what adding a tube to the spout would do.

There is a fill-line marked about an inch or two below the top of the
overflow tube and the problem is that the tank continues to fill past
that mark even when it stops automatcally.
Most of the time the tank will stop filling just as the water starts
spilling into the overflow tube (but even that allows more water than
needed to fill the tank) and other times the float doesn't ever kick up
far enough the to stop the water and I have to lift it by hand.
The stopper is not leaking.

Which adjustment causes the float to rise higher up at a lower water
level so it doesn't keep filling past the fill line?



The screw at the top of the valve controls how high the float rises to
shut the valve. Bending the brass rod (float arm) down should also make
the valve close sooner. However, it looks to me like the the float arm
contacts the center tube so you cannot make the float drop correctly and
then turn off at the correct point. Also the float may rub on the back
wall of the tank. Someone has replaced parts (or it was made that way) so
that the parts don't fit correctly. The float arm needs to be moved
toward the front of the tank to miss the center tube and the float should
be over in the center of the tank (front-to-back). You might be able to
accomplish that by turning the fill mechanism assembly, but that means
turning the water off, draining the tank, loosening the fill mechanism,
twisting it, tightening, and checking for leaks when you refill the tank.



I bent the float arm downward and now it shuts off near the marked fill
line.
The arm must have been bent down when it was first installed and
straightened itself out over 2 years.
