TOOLS NEEDED

5403 UNIVERSAL ADJUSTABLE 3” FLAPPER

MOUNTING

• STEP 01:PREPARE TANK
  SEE INSTRUCTION VIDEO ON WEBSITE FOR REFERENCE.

  • A: TURN OFF WATER

  • B: DRAIN WATER
    Flush toilet to drain most of the water from tank.

  • C: USE SPONGE OR TOWEL TO SOAK UP EXCESS WATER IN TANK

• STEP : 02 REMOVE OLD PARTS

  • A: REMOVE CONNECTOR
    Remove water supply connector from bottom of fill valve by twisting connector nut to the left.
    NOTE: Inspect water supply connector.
    Replace it if it is worn, or you don’t know how old it is, to prevent flooding and property damage.

  • B: REMOVE OLD LOCKNUT
    Below tank, twist locknut to the left to remove from fill valve.

  • C: REMOVE OLD FILL VALVE
    Including refill tube, refill clip and shank washer. Drain any excess water into bucket by removing fill valve from tank. (Pull fill valve up)
    

• STEP 3: REMOVE OLD FLAPPER

  • A: REMOVE FLAPPER CHAIN
    Pinch clasp to unhook chain from tank lever.

  • B: REMOVE FLAPPER FROM FLUSH VALVE SEAT
    Simply unhook or lift flapper arms off the flush valve mounting posts, depending on the type of flapper.

• STEP 4: INSTALL NEW FLAPPER

  • A: INSTALL NEW FLAPPER
    Place flapper on top of flush valve seat and snap arms onto flush valve mounting posts.

  • B: ATTACH FLAPPER CHAIN TO LEVER
    Pinch clasp of clip and attach the clip to the tank lever directly above the flapper. Leave roughly ½ inch of slack in chain. (small “j” shape) To adjust chain length, remove clip and reposition lower on the chain for shorter length.
    Note: We will adjust the flapper dial in Step 9 after setting the proper water level in the tank and bowl.
    TIP: A quick and easy way to adjust the chain length.
    Take the clip off the chain, dangle the chain through the small part of the clip (A), then pull both sides of the chain downward until it snaps into place (B).

• STEP 5: ADJUST HEIGHT OF NEW FILL VALVE

  • A: TWIST FILL VALVE TO ADJUST HEIGHT
    Top of fill valve cap should measure roughly 3″ above top of overflow pipe when installed. NOTE:
    Increasing height allows more water to fill in the tank.

  • If the top of your overflow pipe is not at least 1” below the bottom of the tank lever hole, adjust it. If the overflow pipe is not adjustable, mark the overflow pipe 1” below the bottom of tank lever hole and using a hacksaw, cut the overflow pipe at the specified mark.

  • STEP 6: INSTALL NEW FILL VALVE
    PUSH REFILL TUBE ONTO REFILL PORT FIRST

  • ATTACH REFILL CLIP TO OTHER END OF REFILL TUBE

  • INSERT FILL VALVE Position refill tube to face flush valve making sure fill valve parts do not interfere with lever arm.

  • ATTACH REFILL CLIP TO OVERFLOW PIPE Note: If refill tube is too long to fit inside tank with lid closed, remove refill tube from fill valve refill port, cut tube, and reattach to port.

  • INSTALL LOCKNUT
    Screw locknut to the onto fill valve shank (below tank).

  • Hand-tighten only. DO NOT OVERTIGHTEN.

• STEP 7: FINISHING STEPS

  • A: ATTACH WATER SUPPLY CONNECTOR TO FILL VALVE
    Twist to the right. *Hand-tighten only. DO NOT OVERTIGHTEN.

  • B: TURN ON WATER
    Check for leaks.

  • C: WATER LEVEL
    After the tank stops filling, water level should fill the tank to roughly ½ inch below top of overflow pipe to ensure a proper flush. (Does not need to be exact.)
    Overtightening may damage fill valve or coupling nut, potentially causing flooding. Make sure the float cup does not touch the tank walls or tank lever and flush valve.
    **The top of the overflow pipe must be a minimum of 1″ below tank lever hole.

• STEP 8: FINE-TUNE TANK WATER LEVEL

  • A: FLUSH THE TOILET TO CHECK THE TANK WATER LEVEL
    After the water stops filling the tank, the water level should be roughly ½ inch below the top of overflow pipe to ensure a proper flush.

  • B: WATER LEVEL IS TOO LOW
    Turn the tank water level adjustment screw clockwise to raise the float. Flush to reset water level.
    WATER LEVEL IS TOO HIGH
    Turn the water level adjustment screw counterclockwise to lower the float. Flush to reset water level.

• STEP 9: FINE-TUNE FLUSH

  • A: TEST FLUSH
    Drop 3 squares of toilet paper in bowl then flush.

  • B: ADJUST FOR MOST EFFICIENT FLUSH
    Continue to adjust dial down one setting and flush until toilet is unable to flush paper properly.
    Note: Flapper dial is pre-set to maximum setting (10). If toilet model not listed, keep flapper at default setting 10.
    Hint: The higher the number, the longer the flapper stays open for more water flushed.

  *  **C: FINAL SETTING**  

Once unable to flush paper, adjust dial up one number for final setting.

• STEP 10: FINE-TUNE BOWL WATER LEVEL

  • A: FILL BOWL WITH A GALLON OF WATER
    Wait 1 minute until the bowl water level recedes down and stops.

  • B: MARK THE WATER LEVEL IN THE BOWL
    With a pencil, draw a line at the top of the water level in bowl. (Pencil mark will easily wash off).

  • C: FLUSH TOILET TO CHECK BOWL WATER LEVEL
    If the water level matches the line you’ve made in the bowl when the fill valve stops filling the tank, the water level is correct, proceed to Step 8.
    If the water level matches the line in the bowl and the fill valve is STILL FILLING, then the bowl water is TOO HIGH, proceed to Step 7D.
    If the valve shuts off and the water level does NOT match the line in the bowl, the water level is TOO LOW, proceed to Step 7D.

  • D: ADJUST THE BOWL WATER LEVEL
    TOO HIGH:
    Turn the dial clockwise. TOO LOW:
    Turn the dial counter-clockwise.

  • E: FLUSH TOILET, CHECK BOWL WATER LEVEL
    Repeat Steps 10D and E until water level in bowl matches the line when the fill valve shuts off.

• STEP 11: FLUSH THE TOILET

  • A: FLUSH THE TOILET
    If you’re satisfied with the flush, YOU’RE DONE!

  1/2” below top of overflow pipe is recommended (see page 9).

• C: FLAPPER MAY BE CLOSING TOO SOON
  Give flapper chain approximately 1/2″ of slack (small “j” shape).
