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.

Or you could just replace the mechanism with one
of those where the float is part of the fill fill
valve mechanism.

If it were mine, I would first try turning the
fill mechanism so that the float is free and
misses the center tube. If that didn't work, I
would probably just buy a bit longer arm and bend
it so that it fit correctly. That means you need
to bend it laterally so it misses the center tube
and possibly bending it down as needed at the
float end.

After marking the rod, you need to unscrew it so
that you don't mess up the float or the valve
while you are bending the rod. Then screw it back
in when you finish bending it.
