Adjustable Clip Valve
Step 1
Locate the anti-siphon fill valve. Remove the tank lid off the back of the toilet to reach this valve.
Step 2
Check the style of anti-siphon fill valve you have. Adjust the clips on the metal rod attached to the main pipe valve by squeezing the spring clip.
Step 3
Slide the float up when the water is at a high level or down when you want to conserve more water at a lower level.
Float Ball Valve
Step 1
Adjust the armature by loosening the screw. Move the armature up or down to shorten or lengthen the distance of the float ball to the water. Short distances allow for a higher level of water. Tighten the screw.
Step 2
Remove the armature to adjust it if you cannot move the screw. Unhook the armature from the valve.
Step 3
Bend the metal armature to raise or lower the float ball. Reattach the bent armature to the valve.
