Carefully but firmly wiggle and pull the end of the drain hose off the garbage disposal's inlet nozzle.
Goal: Remove the drain hose from the garbage disposal.

FAQs
Why is an air gap necessary, and is it always required for a dishwasher?
An air gap prevents contaminated drain water from siphoning back into your clean dishwasher, protecting your dishes and health. While not universally required, many local plumbing codes mandate them, so always check your local regulations before installation.
What are the main safety precautions I should take when drilling the hole in my countertop?
Always wear eye protection and gloves. Securely brace the countertop from below if possible, and use the correct hole cutter (like the Malco HC1S) at a slow speed to prevent chipping or cracking. Start with a pilot hole for accuracy and control.
My new air gap is leaking after installation. What should I check first?
The most common leaks occur due to loose hose clamps (ensure they are tightened properly, like the Everbilt 5/16 - 5/8 in. clamps), improperly seated hoses, or damaged gaskets on the air gap body. Double-check all connections and the integrity of any rubber seals.
Is the 4-hour estimated time realistic for a beginner, and what makes it take that long?
Yes, 4 hours is realistic for a beginner. This accounts for thorough preparation, careful drilling (especially for a first-timer), routing hoses, making secure connections, and meticulous testing for leaks, which can take time to get right.
