STEP 7: 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.
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.
D: ADJUST THE BOWL WATER LEVEL
NOTE: “0” on roller clamp equals no refill to bowl.
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 level 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.
TOO HIGH =
