STEP 7: FINE-TUNE BOWL WATER LEVEL
NOTE: The PerforMAX Fill Valve is pre-set to fill the proper
bowl water level in most toilets straight out of the box.
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.
