Shop Dishwasher Air Gaps for a Safe and Code-Compliant Kitchen
A dishwasher air gap is a small but important plumbing device that protects your dishwasher and your kitchen from a specific and often overlooked risk: drain water backflow. Without an air gap or an approved alternative, contaminated water from your kitchen drain can potentially flow back into your dishwasher through the drain hose, which creates a sanitation issue that most homeowners never think about until it becomes a problem.
Inside Out Hardware carries a Designers Impressions dishwasher air gap in oil rubbed bronze, a finish that coordinates naturally with oil rubbed bronze kitchen faucets, cabinet pulls, and other warm-toned kitchen hardware.
The air gap installs through a hole in the sink deck or countertop, typically a pre-drilled hole on the right side of the sink that may currently be covered with a blank plug. The device works by creating a physical gap in the drain line between the dishwasher outlet hose and the kitchen drain. Wastewater must travel up and over this gap to exit the dishwasher, which makes it physically impossible for drain water to flow backward into the appliance.
Many US states, including California, require a dishwasher air gap as part of a code-compliant dishwasher installation. Even in states where it is not mandated, installing an air gap is considered best practice by licensed plumbers and is a standard recommendation in most dishwasher installation guidelines.
Pair your air gap with a matching kitchen faucet and soap dispenser in oil rubbed bronze for a fully coordinated sink deck setup.
Frequently Asked Questions About Dishwasher Air Gaps
A dishwasher air gap prevents contaminated drain water from flowing backward through the dishwasher drain hose and into the dishwasher interior. It works by routing the dishwasher drain hose up to a device mounted above the countertop, then back down to the garbage disposal or drain. The physical height difference, or air gap, between the dishwasher outlet and the drain connection makes backflow impossible without the water having to travel upward against gravity. This protects your dishwasher from drain contamination and is the most reliable backflow prevention method available for residential dishwasher installations.
Dishwasher air gap requirements vary by state and local jurisdiction. California, Washington, and several other states require a dishwasher air gap as part of a code-compliant plumbing installation. Other states allow a high loop drain hose installation as an alternative, where the drain hose is looped up to the underside of the countertop before connecting to the drain. If you are unsure of the requirement in your area, check with your local building department or a licensed plumber before completing your dishwasher installation.
A dishwasher air gap mounts on the sink deck or countertop through a standard 1-3/8 inch hole, the same size used for soap dispensers and some faucet accessories. Most kitchen sinks include one or more pre-drilled holes on the right side of the sink that are covered with a plug when not in use. The air gap body installs through this hole from above, with the drain hose connections made below the countertop. The visible portion above the sink is the decorative cap in your chosen finish, which in our case is oil rubbed bronze.
