Our ALFI brand Air Gap prevents sewer water from flowing back into the dishwasher. As the water flows through the drain hose, it creates a suction on the water that is still in the dishwasher. The air gap provides a hole for air to get in, ensuring that water only leaves the dishwasher when it is pumped out.

• Provides sleek coverage and back-flow prevention for an installed dishwasher.
• Prevents drain water from backing up+into your dishwasher and contaminating your freshly washed dishes with dirty drain water.
• Available in Polished Chrome or Brushed Nickel finishes.
• Easy to install.
