Step 2 · Remove the Air Gap Cover and Cap

To access the air gap for cleaning, you must first remove its decorative cover. Most covers are either threaded or snap-on. Grasp the metal cover firmly and try to unscrew it by turning it counter-clockwise. If it doesn't turn, it is likely a snap-on cover; in this case, pull it straight up to remove it. Once the cover is off, you will see a smaller plastic cap. This cap may also twist off or simply pull up. Remove this plastic cap to expose the inside of the air gap body.
