STEP 1: PREPARE TANK A: TURN OFF WATER TURN CLOCKWISE B: DRAIN WATER Flush toilet to drain most of the water from the tank.
STEP 2: REMOVE OLD FILL VALVE A: REMOVE CONNECTOR Remove water supply connector from bottom of fill valve by twisting connector nut to the left (clockwise). LEFT B: REMOVE OLD LOCKNUT Below tank, twist locknut to the left (clockwise) to remove from fill valve. LEFT Pliers (Optional) C: REMOVE OLD FILL VALVE Drain any excess water into bucket by removing fill valve from tank.
STEP 3: ADJUST HEIGHT OF NEW FILL VALVE A: TWIST FILL VALVE TO ADJUST HEIGHT Top of fill valve cap should measure roughly 3" above top of overflow pipe.

STEP 4: INSTALL NEW FILL VALVE A: INSTALL SHANK WASHER Pull up to top of shank. * Place shank washer onto threaded shank of fill valve. WIDE SIDE UP. Shank Washer Threaded Shank B: PUSH REFILL TUBE ONTO REFILL PORT FIRST Squeeze tube clamp arms and move it towards refill port. C: ATTACH REFILL CLIP TO OVERFLOW PIPE D: INSERT FILL VALVE Position refill tube to face overflow pipe.
E: F: INSTALL LOCKNUT Screw locknut to the right (counterclockwise) onto fill valve shank (below tank). RIGHT ATTACH REFILL TUBE TO REFILL CLIP Squeeze tube clamp arms and move it towards refill clip. Note: If refill tube is too long, cut tube.
STEP 5: FINISHING STEPS A: ATTACH WATER SUPPLY CONNECTOR TO FILL VALVE Twist to the right (counterclockwise) RIGHT B: TURN ON WATER Check for leaks. (See Troubleshooting for leak solutions) TURN COUNTERCLOCKWISE 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. See diagrams on next page.

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. 1/2" Overflow Pipe 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 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.
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. D: TOO HIGH TOO LOW ADJUST THE BOWL WATER LEVEL TOO HIGH = Turn roller clamp with thumb to the next LOWER number. TOO LOW = Turn roller clamp with thumb to next HIGHER number. 0 8 NOTE: “0” on roller clamp equals no refill to bowl.
STEP 8: FLUSH THE TOILET A: FLUSH THE TOILET If you’re satisfied with the flush, YOU’RE DONE! 16

TROUBLESHOOTING IF THE FILL VALVE: • DOES NOT TURN ON • WON’T TURN OFF • WON’T REFILL TANK REMOVE CAP AND CHECK FOR DEBRIS A: Turn off water supply. B: Flush toilet. C: With right hand push float up, grip and hold shaft under float. D: With left hand twist cap and lever arm counterclockwise to unlock cap. Let cap hang on float cup. E: Hold empty cup upside down over uncapped valve to prevent splashing. F: Turn water supply on and off a few times. G: Turn water supply off. H: Replace valve cap.
IF THE FLOAT DOES NOT DROP WHEN FLUSHED REPLACE FILL VALVE SEAL A: Remove cap (see page 18). B: Replace seal with a genuine Fluidmaster 242 Seal. C: Replace valve cap. • Place cap assembly on top of gray valve body by aligning cap arm and adjustment rod next to refill tube. • Press down on top cap while rotating top & arm clockwise to locked position.
TROUBLESHOOTING WATER LEVEL IN BOWL IS TOO LOW A: WATER FROM REFILL TUBE MUST FLOW THROUGH OVERFLOW PIPE Make sure the refill tube is supplying water down overflow pipe. Refill Tube Overflow Pipe B: WATER LEVEL IN TANK MAY BE TOO LOW 1/2” below top of overflow pipe is recommended (see page 12). 1/2" Overflow Pipe C: Roller clamp may need to be adjusted (see page 14). 0 8 D: FLAPPER MAY BE CLOSING TOO SOON Give flapper chain approximately 1/2” of slack.
