Removing Valve Cap Assembly
Turn off the water supply
& flush out the tank. Push
the float up with right hand
(see picture). Grip and hold
the shaft under the float
with right hand. With left
hand, twist the cap and
lever counter clockwise
1/8th of a turn to unlock the
top cap. Pressing down on
the top may be helpful with
older valves. Let the cap
assembly hang on float
cup.
Replacing Valve Cap
A. Place cap assembly on top of gray valve
body by aligning cap arm and adjustment
rod next to refill tube.
B. Press down on top cap while rotating
top & arm clockwise to locked position.
Flushing Out Debris
Hold the cup upside down
over uncapped valve to
prevent splashing. Turn the
water supply on and off a
few times. Turn the water
supply off when putting the
cap back on the valve.
IF FILL VALVEDOESNOT TURN ON, WILL NOT
TURN OFF, OR WILL NOT REFILL THE TANK
AFTER THEFLUSH
•Remove the top cap and check for debris. If you find debris, or flow is
weak: Inspect the lower section of the fill valve for partial blockage.
Partial blockage may be at the shut off valve or in the water supply line
(See “REMOVINGTHEVALVECAP ASSEMBLY & FLUSHING OUT
DEBRIS”).
•If the fill valve has been in use for some time and/or float cup does not
drop when flushing the tank, replace seal with a genuine Fluidmaster
242 seal (See “IFREPLACING SEAL”).
IF FILL VALVE TURNS ON AND OFF BY ITSELF
•This indicates the tank is losing water. The fill valve is refilling lost water.
Clean the flapper and drain seat. If the leak continues, change the flapper
or flush valve. Install Fluidmaster 502, 507AKR, 540AKR or 555C kit.
IF WATER LEVEL IN BOWL IS TOOLOW
•Make sure the refill tube is supplying water down the overflow pipe.
•Water level in the tank may be too low. Raise the water level to 1/2” below
the top of the overflow pipe (See “ADJUSTING TANK WATER LEVEL”).
You may have to lengthen the fill valve in order to increase the water level
in the tank (See “PREPARING THEFILL VALVE FOR INSTALLATION”).
•
The flapper may be closing too soon. Give the flapper chain approximately
1/2” of slack.

Once the fill valve is installed, ensure that the
overflow pipe and water level of the tank are correctly set.
1. THE TOP OF OVERFLOW PIPE (A) must be a minimum of
1" below the TANK LEVER HOLE (B).
2. WATER LEVEL (C) is set below the top of the overflow pipe
(Fluidmaster recommends 1/2”).
3. THE CRITICAL LEVEL MARK / C.L. Mark (D) identified by
C.L. on the fill valve must be positioned 1” above the top of the
overflow pipe. This is a requirement of the Universal Plumbing
Code.
Code Compliance helps protect your home & drinking water
supply.

Inspect water supply connector. Replace if it is worn or over 5
years old to prevent flooding and property damage.
A. Attach the water supply coupling nut to the fill valve. Turn the coupling
nut clockwise by hand until tight.
WARNING: Do not over tighten the nut as it could damage the fill valve or
coupling nut, resulting in flooding and property damage. Fluidmaster Click
Seal®connector is recommended: A perfect seal every time without over
tightening.
B. Turn on the water supply and check for leaks. If you find leaking at
bottom of the tank, turn the nut just enough to stop the leaking. Then flush
the toilet to ensure leaking has ceased.

With the water turned on, set the float cup to the desired
level by turning the water level adjustment screw. Make the
adjustment while the tank is filling.

raise the water level,or counter clockwise to lower the water level.
Repeat if necessary.
HINT: When the adjustment screw is twisted 8 times, the float
moves 1/2”.
