Step 8 · Final Test After Replacement (Optional)

With the new air gap fully installed, conduct a final, thorough test. Place the new decorative cover on top. Run the dishwasher on a 'Drain' or 'Rinse' cycle. While it's draining, use a flashlight to carefully inspect all connections under the sink (both hose connections at the air gap and the connection at the garbage disposal) for any signs of dripping. Also, confirm that no water is sputtering from the top of the new air gap. Wipe each connection with a dry paper towel to make even the smallest leak obvious.
