When it comes to maintaining a clean and safe kitchen, one often overlooked but essential component is the kitchen sink air gap. This small device plays a crucial role in preventing contaminated water from flowing back into your sink and ultimately into your drinking water supply. In this article, we will review the importance of a kitchen sink air gap, how it works, and the top options available in the market in 2023.

What is a Kitchen Sink Air Gap?

A kitchen sink air gap is a device that is installed between your sink and the dishwasher’s drain line. It serves as a barrier to prevent dirty water from the dishwasher from flowing back into the sink and potentially contaminating the clean water supply. The air gap creates a physical break in the water flow, ensuring that any wastewater is properly disposed of without the risk of backflow.

How Does a Kitchen Sink Air Gap Work?

The kitchen sink air gap works on a simple principle of gravity and air pressure. When the dishwasher drains water, it creates a suction force that pulls the wastewater downwards. The air gap interrupts this flow by creating a gap between the dishwasher drain line and the sink’s drain pipe. The gap is filled with air, which prevents the dirty water from flowing back up into the sink. Instead, the wastewater is directed into the sewer system or the disposal system, ensuring proper drainage.
