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.

FINE-TUNE TANK WATER LEVEL

STEP 8:

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.

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.

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.

FINE-TUNE BOWL WATER LEVEL

STEP 10:

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 11.
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 10D.
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 10D.
