What Is A High Loop For Dishwasher

In the world of household appliances, dishwashers have become an indispensable part of our daily lives. These time-saving devices have revolutionized the way we clean our dishes, making the dreaded task of washing up after a meal a breeze. But have you ever heard of a “high loop” for a dishwasher? If not, you’re in for an informative ride as we delve into this important aspect of dishwasher installation and maintenance.

Understanding the Basics

The High Loop Concept

A high loop for a dishwasher refers to a crucial component in the dishwasher’s drainage system. It is a simple yet effective mechanism designed to prevent dirty water from flowing back into the dishwasher. This loop is created by routing the dishwasher’s drain hose in a specific manner.

How Does It Work?

The high loop essentially acts as a barrier that prevents wastewater from the kitchen sink or disposal unit from flowing back into the dishwasher. By elevating a section of the drain hose above the level of the sink or disposal unit, gravity ensures that water only flows in one direction – away from the dishwasher.

The Importance of a High Loop

Preventing Contamination

One of the primary reasons for installing a high loop is to prevent the cross-contamination of clean dishes. Without this loop, there is a risk of dirty water flowing back into the dishwasher during the drainage process, leading to unhygienic conditions.

Avoiding Foul Odors

Another benefit of the high loop is that it helps in keeping foul odors at bay. Stagnant water trapped in the drain hose can emit unpleasant smells over time. By ensuring proper drainage, you can maintain a fresh and odor-free kitchen environment.

Installation and Maintenance

DIY or Professional Installation?

Installing a high loop for your dishwasher can be a DIY project if you are handy with tools and have a basic understanding of plumbing. However, for those less confident in their DIY skills, it’s advisable to seek professional installation to ensure it’s done correctly.

Regular Check-ups

Once the high loop is in place, it’s essential to perform regular maintenance checks. Ensure that the loop remains intact and that there are no kinks or obstructions in the drain hose. Keeping the system clean and functional is key to its effectiveness.

Common FAQs

1. Do all dishwashers require a high loop?

  • No, not all dishwashers require a high loop. Some modern dishwasher models come equipped with built-in mechanisms to prevent backflow. However, it’s still a good practice to have one installed for added protection.

2. Can I install a high loop myself?

  • Yes, you can install a high loop yourself if you have the necessary skills and tools. However, if you’re unsure, it’s best to consult a professional plumber.

3. What should I do if my dishwasher smells bad?

  • If your dishwasher has a foul odor, it’s essential to clean it thoroughly. Additionally, check the high loop and the drain hose for any blockages or trapped debris.

4. Is a high loop the same as an air gap?

  • No, a high loop and an air gap are not the same. An air gap is another method of preventing backflow but involves the installation of a separate device.

5. Can a high loop reduce the risk of leaks?

  • While a high loop primarily prevents backflow, it can also indirectly reduce the risk of leaks by ensuring proper drainage, which helps maintain the integrity of your dishwasher’s components.


In conclusion, a high loop for a dishwasher is a simple yet crucial feature that contributes to the cleanliness and hygiene of your kitchen. It prevents the contamination of clean dishes, keeps foul odors at bay, and ensures the smooth operation of your dishwasher. Whether you choose to install it yourself or seek professional assistance, maintaining a functional high loop is a small but significant step toward a more efficient dishwasher.
