What is an Air Gap for Dishwashers?

An air gap is a crucial component in your dishwasher setup. It’s a critical safety feature that prevents contaminated water from flowing back into the dishwasher.

Air gaps create a physical space between the dishwasher’s drain line and the sink drain. If there’s a backup in your sink, the air gap ensures that dirty water can’t reenter your dishwasher.

In simpler terms, think of the air gap as a protective barrier that keeps your dishwasher and kitchen water separate.
