Turning Off The Water Supply

Before beginning any adjustments, make sure to turn off the water supply to avoid any potential leaks or accidents. Locate the shut-off valve near the toilet and turn it clockwise until it stops.

To adjust the float, locate the float adjustment screw or clip and move it up or down. Test the water level by turning on the water supply momentarily and ensuring the float is at the desired position.

Reassembling The Anti Siphon

Once you have adjusted the float to the correct position, carefully reassemble the Korky Anti Siphon. Make sure all the components are securely fitted and the top cap is tightly screwed back into place. Double-check for any loose connections or leaks before proceeding to the next step.

Testing The Adjustment

Now it’s time to test your Korky Anti Siphon adjustment. Turn on the water supply and wait for the toilet tank to fill up. Observe the water level and make sure it stops at the desired mark. Flush the toilet a couple of times to ensure proper flushing and refilling. If everything is working smoothly, congratulations! You have successfully adjusted your Korky Anti Siphon.
