Step 3 · Clean the Air Gap Body and Cap
With the caps removed, inspect the inside of the air gap body for obstructions. Often, food particles and gunk accumulate here, causing the blockage. Use a small bottle brush or a pipe cleaner to scrub the inside of the air gap body. Use rolled-up paper towels to wipe out any dislodged debris. Clean the plastic cap you removed as well, ensuring any small vent holes are clear. A toothpick can be helpful for clearing these small openings.
