PREPARATION
Remove Old Fill Valve and Flapper
Remove tank lid. Use pencil to mark water level of tank. Then follow steps
A-E.
A. Turn off water supply (Clockwise). Flush toilet and remove excess
water from tank with sponge.
B. Remove water supply coupling nut. Remove locknut from under tank.
C. Remove fill valve from tank.
D. Unhook flapper chain from tank lever.
E. Remove flapper from overflow pipe on flush valve.
Preparing the Fill Valve for Installation
Fill Valve Assembly Parts
A) Refill Clip
B) Refill Tube
C) Shank Washer
D) Locknut
E) Threaded Shank
Place Shank washer onto threaded shank of fill valve. Flat side up.
Position fill valve in tank, but do not fully install yet. Top of fill valve
MUST be set 3” above overflow pipe. This will automatically place CRITICAL
LEVEL MARK / C.L. Mark, 1” above the top of overflow pipe. Remove fill valve
from tank to adjust height.
Adjust height of fill valve by holding lower shank with right hand and top of
valve with left hand. Twist the lower shank counter clockwise to increase
valve height and clockwise to decrease valve height. You should hear several
“clicks”. Place valve in tank and check height again. THE CRITICAL LEVEL MARK,
identified by C.L. on valve, MUST be positioned 1” above top of overflow pipe.
This is a requirement of the Universal Plumbing Code. Do not move lock ring.
It holds the valve body and shank together under pressure. Do not interchange
body with old shank as leaking can occur.
Installing New Flapper
Put flapper on seat and push down on flapper clips at the horizontal posts of overflow pipe. Attach chain clip to tank lever directly above flapper. Leave 1/2” of slack in chain.
Attach Water Supply Connector
Inspect water supply connector. Replace it if it is worn or over 5 years old
to prevent flooding and property damage.
A. Attach water supply coupling nut to fill valve. Turn coupling nut
clockwise by hand until tight.
WARNING: Do not over tighten the nut as it could damage 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 water supply and check for leaks. If you find leaking at
bottom of tank, turn nut just enough to stop leaking. Then flush toilet to
check.
Adjusting Tank Water Level
With water turned on, set float cup to desired level, by turning water level
adjustment screw. When adjusting float cup, flush tank first. Then make
adjustment while tank is filling. To adjust tank water, turn adjustment screw
clockwise to raise water level or counter clockwise to lower water level. Once
adjusted, flush toilet and check new level. Repeat if necessary.
HINT: When you twist adjustment screw 8 times – float moves 1/2”.
Code Compliance
Once fill valve is installed, ensure overflow pipe and water level of tank are correctly set.
1. THE TOP OF OVERFLOW PIPE (A) must be minimum of 1″ below TANK LEVER
HOLE (B).
2. WATER LEVEL (C) is set below top of Overflow Pipe (Fluidmaster
recommends 1/2”).
3. THE CRITICAL LEVEL MARK / C.L. Mark (D) identified by C.L. on fill
valve must be positioned 1” above top of overflow pipe. This is a requirement
of the Universal Plumbing Code.
_Code Compliance helps protect your home & _drinking water supply.
TROUBLESHOOTING
IF FILL VALVE DOES NOT TURN ON, WILL NOT TURN OFF, OR WILL NOT REFILL THE TANK AFTER THE FLUSH
- Remove top cap and check for debris. If you find debris, or flow is weak: Inspect lower section of fill valve for partial blockage. Partial blockage may be at shut off valve or in water supply line (See “REMOVING THE VALVE CAP ASSEMBLY & FLUSHING OUT DEBRIS”).
- If fill valve has been in use for some time and/or float cup does not drop when flushing tank, replace seal with a genuine Fluidmaster 242 seal (See “IF REPLACING 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 flapper and drain seat. If leak continues change flush valve. Install Fluidmaster 507AKR, 540AKR or 555C kit
IF WATER LEVEL IN BOWL IS TOO LOW
- Make sure the refill tube is supplying water down overflow pipe.
- Water level in tank may be too low. Raise water level to 1/2” below top of overflow pipe (See “ADJUSTING TANK WATER LEVEL”). You may have to lengthen the fill valve in order to increase the water level in tank (See “PREPARING THE FILL VALVE FOR INSTALLATION”).
- Flapper may be closing too soon. Give flapper chain approximately 1/2” of slack.
**Removing Valve Cap Assembly, Flushing Out Debris, Replacing Seal, &
Replacing Valve Cap Assembly **
Removing Valve Cap Assembly
Turn off water supply & flush out tank. Push float up with right hand (see
picture). Grip and hold shaft under float with right hand. With left hand,
twist cap and lever counter clockwise 1/8th of a turn to unlock the top cap.
Pressing down on top may be helpful with older valves. Let cap assembly hang
on float cup.
Flushing Out Debris
Hold cup upside down over uncapped valve to prevent splashing. Turn water
supply on and off a few times. Turn water supply off when putting cap back on
valve.
If Replacing Seal
If Replacing Seal: Use only a genuine Fluidmaster 242 seal.
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.
