A)  Refill Clip 

D)  Lock Nut

B)  Refill Hose 

E)  Coupling Nut

C)  Shank & Cone  

F)  Threaded Shank

  Washer 

G)  Shank Washer

Pull Shank and cone washer off the end of the 

Refill Clip. This will release all the assembly 

parts.

Push the cone washer from the center of 

shank washer with your thumb or cut the four 

connections between the shank & cone washer 

with scissors. Set cone washer aside.

Under tank, thread large plastic 

hex nut onto threads of flush valve. 

Tighten lock nut 1/2 turn beyond 

hand tight. Place tank to bowl 

gasket on bottom of flush valve. 

Gasket should cover hex nut.
Place a rubber washer on tank 

bolts. Place tank bolt through 

hole in tank. (optional step: Under 

tank, place a metal washer and 

hex nut, tighten hex nut.) Set tank 

onto bowl. Place rubber washer, 

metal washer and hex nut on to 

bolts under bowl. Tighten hex nuts 

evenly until tank is snug on bowl 

and does not rock.

Before installing flush valve remove tank to bowl 

gasket and hex nut from bottom of flush valve. 

Set flush valve with flush valve seal into opening 

inside of tank.
Cutting the Overflow pipe
Measure 1" down from the bottom edge of the 

tank lever hole and make a mark on the tank wall. 

If the new mark on the tank is above the water 

level mark, cut the overflow pipe at the new mark.
If the water level mark is equal to or above the 

new mark on the tank, the water level is set too 

high. Lower the water level 1/2" below the new 

mark on the tank. Cut the overflow pipe before 

you install the flush valve. Use a pipe cutter or 

hacksaw blade to cut overflow pipe. 

If your tank lever has any bends in 

it, follow step (2A). If it does not 

have any bends in it skip to step 

(2B).

2A) To bend lever start bend 2" out 

from point lever enters tank. Bend 

to match old lever. Do not bend arm 

quickly or back and forth repeatedly.

2B) Push lever through tank hole. 

Slide lock nut onto lever arm round 

flange first. Thread nut until snug. 

Do not overtighten. Lock nut is a 

reverse thread.

Attach one end of REFILL 

HOSE to REFILL CLIP. Place 

clip on right side of overflow 

pipe. Attach other end of hose 

to nipple on fill valve with a 

slight arching of hose. (See 

picture at right.) Cut tube as 

necessary. Do not shove refill 

tube down overflow pipe. This 

will cause water loss.

FILL VALVE WILL NOT TURN OFF 
•  IMPORTANT: Sand and rust moves through 

water pipes. Always clear debris from water 

lines. Repeat the steps to flush out the valve 

(see Step 6).

FILL VALVE WILL NOT TURN ON 
•  IIf fill valve has been in use for some time, 

And float cup does not drop when flushing the 

tank:  Replace 242 seal.

•  If fill valve is new, Remove top cap and check 

for debris. If you find debris clean out. If no 

debris found: Place a coffee cup upside down 

over uncapped valve and turn on water full. 

If strong flow: replace valve. If flow is weak: 

partial blockage further down in valve, at shut 

off or in water supply line.

WATER LEVEL IN BOWL IS TOO LOW
•  Make sure the refill hose is supplying water 

down the overflow pipe.

•  Water level in tank may be too low. Raise 

water level to 1/2” below top of overflow pipe.

•  Flapper may be closing too soon. Give flapper 

chain approximately 1/2 “ of slack. Adjust 

flapper to higher setting.

•  If your toilet is 3.5 gallons per flush or larger, 

the flapper in this kit may not be the correct 

flapper.Pick up a 501 Harsh Water flapper or 

504 all rubber flapper by Fluidmaster.

  CAUTION: Do not shove refill tube down 

overflow pipe. This will cause loss of water 

from tank. Make sure the end of the refill tube 

is higher than the water level of the tank.

Place fill valve in 

tank. Make sure 

lid will sit on top 

of tank. Align 

fill valve nipple 

to face parallel 

with back wall of 

tank. Press down
