What Is a Kitchen Air Gap?
A kitchen air gap is a small device that is installed on the countertop or sink of a kitchen to prevent contaminated water from flowing back into the dishwasher. It is a crucial component of the plumbing system in a kitchen and plays a significant role in maintaining the cleanliness and safety of the water supply.
The purpose of a kitchen air gap is to provide a physical barrier between the dishwasher and the water supply. It ensures that any wastewater from the dishwasher is properly drained and does not mix with the fresh water supply, which could potentially lead to contamination.
How Does a Kitchen Air Gap Work?
A kitchen air gap consists of three main components – the inlet, the outlet, and the air gap itself. The inlet is connected to the dishwasher drain hose, while the outlet is connected to the sink drain or garbage disposal. The air gap is a small cylindrical or dome-shaped device that sits on the countertop or sink.
When the dishwasher is in use, it pumps the wastewater through the drain hose into the inlet of the air gap. As the water fills the air gap, it creates a small air pocket between the outlet and the dishwasher drain hose. This air pocket acts as a barrier, preventing any backflow of wastewater into the dishwasher.
The wastewater then flows out of the air gap through the outlet and into the sink drain or garbage disposal. This ensures that any contaminated water is safely disposed of and does not mix with the fresh water supply.
