A dishwasher air gap separates two branches of hose with a physical gap of air to guarantee that cross-contamination between the dishwasher and drain is impossible. One branch of the air gap fitting connects from the dishwasher to the air gap. The other branch descends from the air gap to the garbage disposal. The hose running the dirty water from the dishwasher exits the dishwasher and curves upward. At its peak, the branch ends and the water pours out of the open mouth of the tube, through the air gap, and down into the second branch. The second branch carries the wastewater down toward the designated drainage site.
How to prevent backflow from dishwasher?
A high loop is a method of backflow prevention where the drain line runs from the dishwasher to the highest point beneath the sink. The loop is affixed to the underside of the counter with a bracket, then drains down into the garbage disposal or sink drain. In a high loop set-up, the drained water from the dishwasher is forced to travel upward before it can flow to the drain. All high loops should measure at least 32” above the floor of the kitchen. If there is not at least 32” of clearance between the floor and the peak of the high loop, you will have to install an air gap. Since the tubing is running at a drastic slope, wastewater is unlikely to backflow through a properly installed high loop. This is known as an air break. If the drain becomes clogged, the waste ideally would back up through the garbage disposal and into the sink rather than back into the dishwasher.
