Are you looking for substitutes for your dishwasher?
If yes, you’ve come to the right place. This article will focus on dishwasher air gap alternatives. If your system is faulty, you’ll know the parts that can serve as substitutes.
Until then, let’s take a look at dishwashers and how they work.
Here is a guide on dishwasher air gap alternatives.
An air gap is an essential component of a dishwasher. It is designed to keep your dishwasher clean and working efficiently. The component protects the dishwasher from flooding with wastewater, which can result in contamination.
However, dishwasher air gaps can become damaged like other household appliances and require replacement.
An Overview of Dishwasher Air Gap
A dishwasher air gap is a small, cylindrical fixture that’s mounted about two inches above or next to the sink. It is designed to prevent contaminated water from re-entering the system through the drain due to backflow.
The dishwasher air gap consists of two hoses. One hose connects to the dishwasher, while the other one connects to the kitchen drain or garbage disposal.
You don’t have to worry about the risks of wastewater creeping back into your clean appliance. That’s because the two hoses do not intersect with each other.
How Dishwasher Air Gap Works
Let’s briefly explain how a dishwasher air gap prevents cross-contamination between the dishwasher and garbage disposal. As stated above, the system has two hoses, one of which is connected to the dishwasher and the other to the garbage disposal.
The hose connected to the dishwasher runs dirty water and exits upward.
It pours water out through the open mouth of the tube down into the second hose. The second hose carries the wastewater to the designated site.
Dishwasher air gaps are often installed beneath the sink. It has a decorative heading that extends above the sink. It is also notched with holes that will release water into your sink in the event of a clog.
Dishwasher Air Gap Options
Dishwasher air gap alternatives are ideal for those who dislike the dishwasher air gap’s pronounced appearance on their sink. If you live in an area that does not mandate air gaps, consider other backflow prevention options.
Regardless of the case, there are two excellent alternatives to this system. Let’s check them out.
-
High Loop
A high loop is a classic and effective method for preventing backflow.
It involves routing the dishwasher’s drain hose to a high point under the sink before going down the drain. The loop is often affixed to the underside of the counter with a bracket before draining down into the garbage disposal.
A high loop uses gravity to prevent dirty water from flowing back into the dishwasher. It is measured around 32″ above the floor of the kitchen. When installed properly, it is unlikely for wastewater to backflow.
However, you must know that a high loop is not as safe as an air gap. That’s because it cannot assure back-siphonage prevention. If there’s a significant drop in water pressure, the water flow can reverse.
Eventually, the dishwasher drain can suction dirty water and bacteria into the appliance. Another con with high loops is the risk of loose, sagging, or poor installation.
-
Standpipe
Another excellent alternative for dishwasher air gaps is a standpipe.
It’s a vertical pipe into which the dishwasher drains. The pipe is located above a P-trap, a plumbing fixture that prevents sewage and odors from backing up into your home through the drain.
For maximum efficiency, the standpipe is to be vented at least two inches in diameter to prevent backflow. It must also be taller than the sink’s overflow level to prevent water from entering your cabinet.
A standpipe is overly complicated and less effective than an air gap and high loops. It also requires excessive plumbing work. Before choosing this alternative, it’s essential to weigh the pros and cons.
Most plumbers would never recommend a standpipe as an alternative to a dishwasher.
Is It Mandatory to Install a Dishwasher Air Gap?
The answer is yes. Several factors make this component an integral part of the dishwasher.
As stated earlier, the primary function of an air gap is to prevent backflow of wastewater. Usually, changes in water pressure pose a risk of dirty water being sucked back into the dishwasher.
Secondly, it’s a way of complying with plumbing codes. Some states in the U.S. made the installation of dishwasher air gaps mandatory. Among these states are California, Minnesota, Washington, and Hawaii.
Lastly, installing an air gap in your dishwasher is a hygienic measure. By preventing the backflow of contaminated water, you’ll keep your family safe from harmful bacteria and germs.
Tips for Installing a Dishwasher Air Gap
Having seen some excellent alternatives for dishwasher air gaps, it’s essential to know how to install the component. You don’t necessarily need to call an HVAC technician or plumber to do the job.
You can do it yourself and save hundreds of dollars.
The first step is to gather the necessary materials. These include hose clamps, screwdrivers, dishwasher air gap fittings, drills, and more.
Having obtained the needed items, the next step is to locate or drill a hole in the countertop. Some counters have pre-cut holes for the air gap.
If there is none, then drill a hole approximately 1 3/8 inches from the sink rim. Before starting the installation, disconnect the dishwasher from the power source to ensure safety during the process.
After that, connect the dishwasher’s drain hose to the smaller leg of the air gap. Ensure you secure it with a hose clamp. Once you’re done, connect the sink drain or garbage disposal. You can do that by cutting and connecting a length of 7/8″ tubing from the air gap to either the sink drain or garbage disposal.
When you’re done, secure the air gap on the counter with a nut and secure it in place. Test for leaks afterward to ensure you’ve done the right thing. Run the dishwasher on a complete cycle to check for any leaks.
Tips for Maintenance
It’s essential to maintain your dishwasher’s air gap to ensure it continues functioning properly and prevents potential water damage in your home. Regularly clean and maintain your garbage disposal to prevent clogs and odors.
Be sure to check the dishwasher on a fill cycle for any leaks.
Additionally, be sure to regularly check the dishwasher’s drain hose for any clogs or blockages. This will help ensure that your dishwasher is functioning correctly and not causing any leaks or flooding in your home.
A dishwasher air gap is an essential component to prevent backflow of water into the dishwasher. If the part is damaged or malfunctioning, alternative solutions are available to avoid potential damage.
These include installing a high loop in the drain hose or using a check valve.
