The use of an air gap is required by plumbing codes for certain plumbing fixtures, such as dishwashers, to prevent the backflow of potentially contaminated water into the clean water supply. If contaminated water backflows, it can cause serious health risks.
What If My Dishwasher Has No Air Gap? Without a dishwasher air gap, contaminated water can flow back into the dishwasher. A dishwasher air gap prevents this from happening by ensuring that the water flows in one direction: out of the dishwasher and into the garbage disposal.

Both the high loop and air gap methods serve the same purpose of preventing wastewater backflow and are commonly required by building codes to ensure the safe operation of dishwashers. The specific requirements may vary depending on your location and local plumbing codes.
Three compartment sinks should have TWO AIR GAPS.
When drain lines aren't properly vented, low pressure inside the pipe can suck water out of the traps, letting sewer gas in. Air pressure imbalances inside the drain pipe can restrict water flow and cause sluggish draining, often mimicking a partial clog inside the pipe.
* An air gap between the water supply inlet and the flood level rim of the plumbing fixture, equipment, or nonfood equipment shall be at least twice the diameter of the water supply inlet and may not be less than 25 mm (1 inch).
Contact a dishwasher repair service near you to clear the line of clogs and bring your air gap back into shape. Having a pro replace a dishwasher air gap costs between $80 and $150.

Check the exterior caulking around doors and windows, and see whether exterior storm doors and primary doors seal tightly. Inspect windows and doors for air leaks. See if you can rattle them, since movement means possible air leaks. If you can see daylight around a door or window frame, then the door or window leaks.
They rely solely on basic physics and gravity to do their job. If you have a garbage disposer and a dishwasher, you will definitely want to use an air gap.
Plugged at the U-pipe, the fresh water blocks sewer gases and lets them harmlessly leak out the plumbing vents. Every plumbing fixture needs to have a vent to work properly.
When there is a clog in the line, and it's not draining properly, water pressure in the pipes can increase and force sink water up into the dishwasher drain line. One way to relieve the pressure is to disconnect the sink trap (P trap) underneath the sink and remove the blockage.
