A dishwasher air gap is a device that prevents wastewater from flowing back into your clean dishwasher. It creates a physical break in the drain line to avoid cross-contamination. Most plumbing codes require one for safety and hygiene reasons.
Measure the diameter of the hole in your sink deck and the pipe dimensions before buying. Most models fit standard 1.5-inch holes but some are larger. Universal designs are available but checking specs ensures compatibility.
