How to Adjust a Korky Toilet

A leaking or improperly adjusted toilet can waste up to 6,500 gallons of water a year. That's why it's important to catch leaks as early as you can. Korky manufactures a number of toilet parts and accessories to help you save as much water as possible. You can adjust both the fill valve and the flapper on toilets equipped with Korky parts.

Step 1

Take the lid off the toilet tank and set it aside.

Step 2

Locate the Korky fill valve on the left-hand side of the toilet tank.

Step 3

Grasp the top head of the fill valve and rotate it counterclockwise to unlock.

Step 4

Move the fill valve head up or down to adjust the water level. When making adjustments, the "critical level" (C/L) line on the fill valve head needs to be at least an inch above the top of the overflow tube in the center of the tank.

Step 5

Rotate the Korky head clockwise to lock into position. Insert the tamper-proof wedge underneath the fill valve head and snap it onto the tabs on the side of the fill valve.

Step 6

Raise or lower the float on a Korky adjustable flapper to adjust the flush capacity. Move the float toward the top of the float chain for a shorter flush, which will save water, or push it toward the flapper for a longer flush. Increasing the flush time uses more water but produces a more forceful flush.
