level in the tank and bowl.
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.
STEP 5: ADJUST HEIGHT OF NEW FILL VALVE
1/2” Slack
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).

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.
Do not lift lock ring out of
locked position.
*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 8: FINE-TUNE BOWL 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.

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 (9).
A: TEST FLUSH
Drop 3 squares of toilet paper in
bowl then flush.
C: FINAL SETTING
Once unable to flush paper, adjust dial up one number for
final setting.
Hint: The higher the number, the longer the flapper stays open for more
water flushed.

STEP 11: FLUSH THE TOILET
A: FLUSH THE TOILET
If you’re satisfied with the flush, YOU’RE DONE!

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.
TOO HIGH
TOO LOW
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.
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.
D: ADJUST THE BOWL WATER LEVEL
NOTE: “0” on roller clamp equals no refill to bowl.
TOO HIGH =
TOO LOW =
