When it comes to maintaining a spotless kitchen, a reliable dishwasher can be your best friend. Among various dishwasher brands, Whirlpool stands out for its efficiency and innovative features. However, many homeowners often wonder, “Does a Whirlpool dishwasher need an air gap?” This topic is critical as it impacts the installation, functionality, and most importantly, the hygiene of your kitchen appliances. In this article, we will explore the necessity of an air gap in Whirlpool dishwashers, going in-depth to cover its benefits, installation tips, and alternatives.
What is an Air Gap?
An air gap is a plumbing fixture designed to prevent contaminated water from siphoning back into your clean water supply. Typically installed above the sink, it serves as a safeguard against backflow. When a dishwasher drains, water can potentially flow back into the water supply if there is a drop in pressure. This is where the air gap comes into play.
How Does an Air Gap Work?
The air gap works on a simple yet effective principle. It separates the water from the dishwasher from the water supply. Here’s how it functions:
- Dishwasher Drainage: When your Whirlpool dishwasher expels water, it goes through a drain hose connected to the air gap.
- Successful Drainage: The air gap allows the water to flow into the sink drain while maintaining an air pocket that prevents any suction effect that could draw water back.
- Prevention of Contamination: If any backflow occurs, it rises in the air gap and spills into the sink rather than contaminating the clean water supply.
Do Whirlpool Dishwashers Require an Air Gap by Code?
Understanding whether an air gap is necessary begins with local plumbing codes.
Codes and Regulations
In many areas, plumbing codes require an air gap for dishwashers to ensure safe water management. Here are some guidelines to consider:
- Local Building Codes: Check your municipality for specific requirements regarding dishwasher installations.
- State Regulations: Different states might have varying rules about air gaps, often grounded in health and safety concerns.
Typically, if you live in a region where the plumbing code mandates an air gap, you should follow this requirement for your Whirlpool dishwasher. Failing to comply may lead to backflow issues and health risks.
Benefits of Installing an Air Gap
Even if local regulations do not strictly require one, there are several compelling reasons to install an air gap with your Whirlpool dishwasher.
1. Enhanced Safety
Air gaps significantly enhance safety in terms of preventing potential health hazards. They ensure that no contaminated water can mix with your drinking water supply, thereby protecting your family.
2. Compliance with Local Codes
Staying compliant with local plumbing codes is crucial for home inspections, especially if you plan to sell your property. An air gap can contribute positively to your home’s assessment.
3. Preventing Drainage Issues
An air gap reduces the likelihood of drainage problems. If your dishwasher cannot drain correctly, it can lead to water pooling and may require servicing. By incorporating an air gap, you can enhance the drainage performance of your dishwasher.
4. Increased Lifespan of Your Dishwasher
An air gap may also contribute to the longevity of your Whirlpool dishwasher. Less strain on the drainage system means that your appliances will face less wear and tear over time.
Can You Install a Whirlpool Dishwasher Without an Air Gap?
Yes, you can technically install a Whirlpool dishwasher without an air gap if it’s allowed by local plumbing codes. However, this option comes with risks and potential issues.
Potential Risks of Not Having an Air Gap
Installing a Whirlpool dishwasher without an air gap can lead to:
- Contamination Risks: Dirty water could siphon back into your clean water supply.
- Compliance Issues: You might face challenges during property evaluations.
- Increased Maintenance: The risk of clogs and drainage issues may increase.
Given these drawbacks, it is generally advisable to opt for an air gap installation.

How to Install a High Loop
- Attach the Drain Line: Secure the dishwasher’s drain line to the underside of the countertop using a strap or bracket.
- Bend the Drain Line: Create a loop in the hose, ensuring the highest point is at least 20 inches above the floor.
- Connect to Sink Drain: Attach the drain line to the sink drain, making sure it’s properly secured.
Conclusion
In summary, while a Whirlpool dishwasher can operate without an air gap in certain scenarios, installing one is often advisable to enhance safety, comply with local plumbing codes, and improve the appliance’s lifespan. The air gap serves as a vital line of defense against contamination, ensuring a clean and efficient kitchen environment.
Before deciding whether to incorporate an air gap into your Whirlpool dishwasher, consult local regulations, weigh the benefits discussed, and consider your specific household needs. With proper installation and preventive maintenance, your dishwasher can offer years of reliable service—keeping your plates clean and your kitchen safe. So, as you plan the setup of your Whirlpool dishwasher, remember the air gap; it just might be a small fixture that saves you from significant issues in the long run!
Do Whirlpool dishwashers need an air gap?
Yes, Whirlpool dishwashers typically require an air gap to ensure proper drainage and prevent backflow of dirty water into the clean water supply. An air gap creates a physical separation between the dishwasher and the household plumbing system, which helps to maintain the intended flow of water. This is particularly important in areas where local plumbing codes mandate the installation of an air gap.
In many regions, building codes require an air gap for dishwashers to comply with safety regulations. This installation not only prevents contamination but also enhances the overall efficiency of your dishwasher. If you’re unsure about the specifications for your model, you can check the user manual or consult a plumbing professional.
What does an air gap do?
An air gap is a plumbing fitting that allows for a break in the flow of water between the dishwasher and the sink drain. This gap prevents dirty water from siphoning back into the dishwasher, ensuring that the clean water used for washing dishes remains uncontaminated. The air gap typically consists of a small plastic or metal fixture located on the countertop or sink, with two connections: one to the dishwasher and the other to the waste line.
In addition to preventing backflow, an air gap also helps to alleviate pressure that builds up in the drainage system. By allowing excess water to flow out without creating a vacuum, air gaps can help avoid clogs and maintain consistent drainage performance. This ultimately improves the overall effectiveness and life span of your dishwasher.
Is an air gap required by plumbing codes?
Yes, most plumbing codes in North America require the installation of an air gap for dishwashers. The requirement is intended to safeguard the drinking water supply by preventing any potential contamination from wastewater. Local codes may vary, so it is always a good idea to check with your local authority or plumbing inspector to ensure you are in compliance with the specific regulations in your area.
It’s important to note that while an air gap is commonly mandated, there may be alternatives available, such as high loops that can also prevent backflow. However, air gaps are generally regarded as the most reliable method of safeguarding against contamination and are often recommended by appliance manufacturers, including Whirlpool.
What happens if I don’t install an air gap?
If you choose not to install an air gap for your Whirlpool dishwasher, there is a risk that dirty water could siphon back into the dishwasher during the drainage process.

Additionally, it can result in unpleasant odors and a compromised cleaning performance.
Neglecting to install an air gap may also conflict with local plumbing codes, potentially leading to fines or the need for costly modifications down the line. Moreover, if plumbing inspectors find that your dishwasher installation does not meet code requirements, it could result in the denial of building permits or future home insurance claims.
How do I install an air gap for my Whirlpool dishwasher?
Installing an air gap for your Whirlpool dishwasher is a straightforward process that generally involves a few tools and materials. First, you’ll need to purchase an air gap kit, which can be found at most hardware stores. Begin by selecting an appropriate location for the air gap, ideally on the countertop or sink, and then drill a hole if necessary. The installation usually consists of connecting the air gap to both the dishwasher and the sink drain.
Once the air gap is in place, use a hose clamp to secure any hoses and check for leaks. After installation, it’s essential to test the system by running a cycle to ensure that everything drains properly without any backflow. Always refer to the installation instructions provided with the air gap kit and your dishwasher owner’s manual for specific guidelines relevant to your model.
Can I use a high loop instead of an air gap?
A high loop can be used as an alternative to an air gap, but it may not satisfy all plumbing codes. A high loop involves placing the dishwasher drain hose higher than the sink or garbage disposal, preventing backflow. This method can be effective in minimizing potential contamination issues. However, it might not provide the same level of assurance as an air gap, particularly in areas with strict plumbing codes.
If you choose to install a high loop instead of an air gap, it’s important to check your local building codes to ensure compliance. In many instances, using both may be the best approach for optimal protection against contamination and to meet code requirements. If unsure, consulting with a plumbing professional can help clarify the best solution for your dishwasher installation.
