Can I connect my dishwasher drain directly to the waste disposal or do I have to connect the dishwasher drain to an air gap first?

  • Are you using the dishwasher port on a garbage disposer? That effectively is an air gap itself. The dishwasher then dumps into the disposer chamber and drains from there.

If you connect above the U bend or P trap this will work. If the connection is below the U bend or P trap sewer gasses can enter the home these can be both unhealthy and explosive.
