When to Use an Air Gap for Your Dishwasher

An air gap is a crucial component that helps maintain proper drainage and prevents backflow of wastewater into your dishwasher. It provides protection against backflow and ensures proper drainage, promoting a safe and hygienic kitchen environment. Use an air gap for your dishwasher when it is required by local building codes or if your dishwasher does not have a built-in high loop configuration. It provides added protection against backflow and ensures proper drainage.

When to Use an Air Gap

1. Building Codes: Many states and local building codes require the installation of an air gap for dishwashers. It is important to check your local regulations to determine whether an air gap is mandatory in your area.
2. Non-High Loop Dishwasher: If your dishwasher does not have a built-in high loop configuration, using an air gap becomes essential. The high loop method is an alternative to the air gap, but it may not be sufficient in certain situations, making the air gap the preferred choice.
3. Additional Protection: Even if not mandated by code, using an air gap provides an extra layer of protection against potential drainage issues and backflow, ensuring the overall safety of your dishwasher and home.

Benefits of Using an Air Gap

Here are a few reasons why using an air gap is beneficial:

• Prevents Backflow: The primary function of an air gap is to prevent contaminated water from the sink or disposal from flowing back into the dishwasher. This is crucial in maintaining the cleanliness and hygiene of your dishes.
• Ensures Proper Drainage: An air gap allows proper drainage by creating a break between the dishwasher and the drain. This prevents clogs and ensures efficient water flow during the dishwasher’s operation.

  

• Safeguards Against Plumbing Issues: In the event of a drain blockage or backup, the air gap acts as a barrier, preventing any potential damage to your dishwasher or home. It provides peace of mind by reducing the risk of water damage or flooding.
