How to Replace a Korky® Toilet Flapper

STEP 1: First, ensure that the water supply valve is turned completely open and that the supply line is free of kinks. If the supply line was kinked or if it was necessary to turn the water supply open, flush the toilet to observe the water flow.

STEP 2: If this was not the problem turn the water supply off.

STEP 3: Pinch the refill tube and cover together to ensure the cap on the valve is completely tightened. After pinching, turn the water supply on and flush to see if the valve is working properly.

STEP 4: If this does not improve water flow, turn the water supply off and flush to empty the tank. Make sure to hold the valve firmly through all steps so it does not get turned out of the locked position.

STEP 5: Next remove the refill tube; you may need to twist slightly.

STEP 6: To remove the valve cover, place your thumb under the tab and lift up. Please note, the color of your Korky fill valve cover may vary by model number. 

STEP 7: Once the cover is off, remove the float by gently pinching the float arms towards each other (the float is the piece that has an X at the top).

STEP 8: Now, remove the cap assembly by grasping the cap firmly and turning it counter-clockwise one eighth turn (it looks like it has a set of rail road tracks at the top). While turning the cap assembly with your free hand, hold the body of the valve in place to prevent the valve from unlocking. We recommend rinsing under warm water to remove any trapped debris. 

STEP 9: Remove the supply tube from the valve by pulling straight and out of the valve (the piece that looks like a wagon wheel). 

STEP 10: Pull the white strainer from the bottom of the supply tube. Rinse the strainer under warm water to remove any sediment.

STEP 11: Now, insert the strainer back into the supply tube and insert the supply tube back into the valve body. Twist the cap assembly clockwise to lock it onto the fill valve.

STEP 12: Once completed, reattach the float arms to the valve body. Pinch the float arms inward to clip them back into place. Tap the “X” on the float to make sure the float moves up and down freely inside of the black box, and is not scraping the sidewalls of the float chamber.

STEP 13: Reattach the fill valve cover onto the valve and connect the refill tube. Ensure refill tube is clipped to the lip of the overflow tube. Never insert the refill tube down into the overflow tube; doing so may create a siphon and cause the valve to run continuously.

STEP 14: Make sure the valve is locked into place by turning it clockwise.

STEP 15: Pinch the refill tube and the cover to make sure the cap is completely tightened.

STEP 16: Turn the water supply on to test water flow.
