Can Your Dishwasher Air Gap Be Under The Sink? Here’s The Truth!

Installing a dishwasher air gap is a crucial step in ensuring proper drainage for your dishwasher. But where should this essential component be located? Can the dishwasher air gap be under the sink? Join us as we delve into the intricacies of dishwasher air gaps and explore this question thoroughly.

What is a Dishwasher Air Gap?

A dishwasher air gap is a small device that prevents contaminated water from flowing back into your dishwasher. It consists of a loop of tubing that creates a break in the drain hose, allowing air to enter the system. This prevents a vacuum from forming, which can cause water to siphon back into the dishwasher.

Why is an Air Gap Important?

An air gap is essential for the following reasons:

• Prevents Contamination: It blocks contaminated water from entering the dishwasher, ensuring that your dishes are washed in clean water.
• Prevents Siphoning: It prevents water from siphoning back into the dishwasher, reducing the risk of flooding.
• Complies with Building Codes: Most building codes require the installation of an air gap for dishwashers.

Can Dishwasher Air Gap Be Under Sink?

Yes, the dishwasher air gap can be under the sink. This is a common location for the air gap, as it provides easy access for installation and maintenance.

Benefits of Under-Sink Air Gaps:

• Easy Access: They are easily accessible for troubleshooting and repairs.
• Protects Air Gap: They are protected from accidental damage or removal.

Where Else Can an Air Gap Be Located?
