The water supply line supplies fresh water into the dishwasher, and the drain line removes dirty water. The electrical connection powers the dishwasher. There are various types of connections to the plumbing for dishwashers, including direct plumbing, air-gap, and high-loop. Direct plumbing links the dishwasher to the household water supply and drain lines. An air-gap connection prevents the flow of dirty water back to the dishwasher using a physical gap between the drain line for the dishwasher and the drain in the sink. A high-loop connection is a looping of the drain line of the dishwasher up to the countertop’s underside and then looping it back down towards the drain, to prevent backflow.
