E: INSTALL LOCKNUT
Screw locknut to the right onto fill valve shank (below tank).

*Hand-tighten only.

STEP 5: FINISHING STEPS

Twist to the right to tighten.

*Hand-tighten only.
DO NOT OVERTIGHTEN.

B: TURN ON WATER Check for leaks.
(Go to www.Fluidmaster.com/support for leak solutions.)

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 6: 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 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.

D: ADJUST THE BOWL WATER LEVEL

IF TOO HIGH: Turn the dial towards the closed position.

IF TOO LOW : Turn the dial towards the open position.

E: FLUSH TOILET, CHECK BOWL WATER LEVEL
Repeat Steps 7D and 7E until water level in bowl matches the line when the fill valve shuts off.

STEP 8: FLUSH THE TOILET

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

YOU DID IT!

We knew you could!
