When it comes to kitchen plumbing, particularly with dishwashers, understanding the differences between a dishwasher air gap and a high loop is essential for compliance with plumbing codes. Each method serves the critical function of preventing wastewater from siphoning back into your dishwasher. This article provides an in-depth look at these two options and their code requirements to help you make informed decisions.

Understanding Dishwasher Air Gaps

Definition and Functionality

A dishwasher air gap is a plumbing device installed above the sink or countertop. It consists of a small cylindrical fixture that ensures the proper drainage of wastewater. The air gap physically separates the dishwasher’s drainage system from the home’s plumbing, effectively preventing any backflow.

Code Requirements

Many plumbing codes, including the International Plumbing Code (IPC), mandate the use of an air gap in residential installations. This requirement is particularly prevalent in locations where cross-contamination must be avoided. Installing a dishwasher air gap not only complies with codes but also enhances the safety and hygiene of your kitchen.

Exploring the High Loop Method

What is a High Loop?

The high loop method involves raising the dishwasher drain hose to a point higher than the dishwasher before connecting it to the sink drain or garbage disposal. This arrangement relies on gravity to keep wastewater from flowing back into the dishwasher.

Code Compliance

While a high loop may be easier to install, it does not meet the strict code requirements set forth in many regions. The lack of a physical separation can lead to potential health hazards, particularly in homes with older drainage systems that may not provide adequate protection against backflow.

Comparing the Two: Air Gap vs. High Loop

Key Differences

• Installation Location: An air gap is installed above the countertop, while a high loop is integrated with the dishwasher drainage hose.
• Effectiveness: The air gap provides a physical barrier against backflow, whereas the high loop relies on gravity alone.
• Code Compliance: An air gap often meets local plumbing codes better than a high loop, which may not be compliant with stringent regulations.

Benefits of Choosing an Air Gap

• Safety: Provides the highest level of protection against wastewater contamination.
• Code Compliance: Ensures adherence to local plumbing codes.
• Durability: Typically requires less maintenance than a high loop.
