Thank you for your question regarding the Delta Kitchen Air Gap and I am happy to help you today.
An air gap is installed to prevent backflow or backsiphonage of non potable water into potable water systems. It is most often installed for use with dishwashers. The air gap prevents the dirty water leaving the dishwasher from getting back into the dishwasher and are typically installed on the counter nearest to the dishwasher. To install the air gap, you will need to connect the larger leg below the counter to a garbage disposal or sink trap and the smaller leg to the hose from the dishwasher. Only the cover and a few inches of the body will be visible from above the counter as the collar gasket and nut will hold the air gap in place.
