- A dishwasher air gap is a cylinder fitting that connects the kitchen sink drain to the dishwasher.
-
It prevents dirty water from entering the clean dishes and also prevents water from flowing back out during a cleaning cycle
-
The air gap works by separating two branches of hose with an unpressurized gap of air to prevent cross-contamination between the dishwasher and drain
- It is typically located about two inches above the sink and is covered by a chrome or stainless steel cylinder
-
The air gap is necessary to prevent backflow and siphoning of dirty water into the dishwasher, which could lead to contamination of the dishes
-
Many plumbing codes mandate the use of air gaps to ensure the safety and proper functioning of dishwashers
-
The air gap is an effective anti-backflow device and should not be substituted with other methods of backflow prevention
