An air gap is a device that is commonly found in dishwashers to prevent contaminated water from backflowing into the dishwasher. This device is typically installed on the countertop, next to the sink, and serves as a connection point between the dishwasher’s drain hose and the sink’s drain. It is an essential component of a dishwasher that ensures the safety of the dishwasher’s user by preventing the contamination of the dishwasher’s water supply.
In this article, we will explore what an air gap is, how it works, and why it is essential for a dishwasher.

What is an air gap?
An air gap is a small device that is typically installed on the countertop, next to the sink. It is designed to provide a physical separation between the dishwasher’s drain hose and the sink’s drain. It consists of a small cylinder with a plastic cover that contains a small opening or channel that allows air to enter the device.
How does an air gap work?
The air gap works by creating a physical barrier that prevents contaminated water from backflowing into the dishwasher. When the dishwasher is in use, water is pumped out of the dishwasher through the drain hose and into the air gap. As the water flows into the air gap, it creates a small pool of water in the cylinder. The pool of water acts as a seal that prevents contaminated water from flowing back into the dishwasher.
As the water continues to flow, the air is drawn into the device through the small opening or channel in the plastic cover. This air creates a vacuum that pulls the water out of the air gap and into the sink’s drain. The air gap essentially serves as a vent that allows air to enter the system and prevent a vacuum from forming in the drain line.
Why is an air gap essential for a dishwasher?
An air gap is essential for a dishwasher for several reasons. The primary reason is to prevent contaminated water from backflowing into the dishwasher. Contaminated water can contain harmful bacteria, viruses, and other pathogens that can cause serious health issues.
An air gap is also required by most plumbing codes and regulations. These codes and regulations are in place to ensure the safety of the water supply and to prevent the contamination of the water. By installing an air gap, homeowners can ensure that their dishwasher meets these codes and regulations and is safe to use.
Another reason an air gap is essential for a dishwasher is to prevent damage to the dishwasher. Backflowing water can cause significant damage to the dishwasher’s components, including the motor, pump, and other electrical components. This can lead to costly repairs and even the need to replace the entire dishwasher.
How to install an air gap for a dishwasher?
Installing an air gap for a dishwasher is a relatively simple process that can be done in a few steps. Here is a step-by-step guide on how to install an air gap for a dishwasher:
Step 1:
Turn off the water supply to the sink and the dishwasher. This is an essential step that will ensure that there is no water flowing through the pipes while you are working on the installation.
Step 2:
Remove the cover from the air gap by unscrewing it from the cylinder. Set the cover aside.
Step 3:
Insert the dishwasher’s drain hose into the bottom of the air gap. The hose should fit snugly into the opening.
Step 4:
Connect the air gap to the sink’s drain by using a hose or pipe. The hose or pipe should be long enough to reach from the air gap to the sink’s drain.
Step 5:
Attach the cover to the top of the air gap by screwing it back onto the cylinder.
Step 6:
Turn on the water supply to the sink and the dishwasher. Check for any leaks or other issues that may arise during the installation.
What is the air gap on a dishwasher?
The air gap on a dishwasher is an important part of the plumbing system. It is a device that prevents dirty water from being siphoned back into the freshwater supply. It consists of two pipes, one connected to the drain hose and one connected to the sink or garbage disposal. The air gap allows air to enter the pipe, creating a break in the siphon effect and preventing any contaminated water from entering the freshwater supply.
The air gap also helps to prevent clogs in the dishwasher’s drain line by allowing air to escape and helping to keep the drain open. If it becomes blocked, it can cause serious damage to both your dishwasher and your home’s plumbing system. It is important to regularly inspect your air gap for any blockages or signs of wear and tear, as these can be indicative of a potential problem with your dishwasher’s drainage system
