Most plumbing codes require an air gap between the dishwasher drain hose and the inlet to the garbage disposal. The purpose of this air gap is to prevent dirty water from being siphoned back into the dishwasher. Some states have adopted additional requirements for dishwasher air gaps.
For example, Colorado requires that the air gap be at least 1 inch (25 mm) wide, while Arizona requires a minimum width of 2 inches (51 mm).
If you live in a state that requires a dishwasher air gap, congratulations! You are one of the few who are keeping their dishwashers up to code. An air gap is a small opening between your dishwasher drain and your sink’s P-trap.
This opening allows air to enter the dishwasher as water is draining, which prevents dirty water from being siphoned back into your clean dishes.Some states, like California, have very specific requirements for dishwasher air gaps. The air gap must be at least 3/8 inch wide and 1 inch high, and it must be installed so that the top of the air gap is no higher than 12 inches above the flood level rim of the sink.
Other states have more general requirements, such as “the air gap must prevent backflow” or “theairgap must be installed according to manufacturer’s instructions.”Why do some states require an air gap while others do not? Well, it all has to do with safety.
A dishwasher that does not have an adequate air gap can allow dirty water (and even sewage) to be sucked back into the machine and contaminate your dishes. In some cases, this can lead to serious illness – even death. So if your state requires an air gap, make sure you comply!

Do I Need A Dishwasher Air Gap?…My States Plumbing Code says YES!!
Are Air Gaps Required for Dishwasher?
Dishwashers are one of the most commonly used appliances in the kitchen. They save time and energy by cleaning dishes quickly and effectively. However, dishwashers also require proper maintenance in order to function properly.
One important aspect of maintaining a dishwasher is ensuring that there is an air gap between the dishwasher and the sink.An air gap is a small space or opening between two objects that allows air to circulate. In the case of a dishwasher, the air gap ensures that water can flow freely from the dishwasher to the drain without being obstructed.
Without an air gap, water could become trapped in the dishwasher and cause problems such as leaks or flooding.Air gaps are typically installed under the countertop near the sink. There should be a hole in both the countertop and sink for the air gap to fit into.
The air gap must then be connected to the drainage system with a rubber hose or PVC pipe. This will allow water to flow out of the dishwasher and into the drainage system when it is turned on.It is important to note that some local building codes may require an airgap even if your model does not come with one pre-installed.
What Happens If Your Dishwasher Doesn’T Have an Air Gap?

Assuming you have all the necessary tools, installing a dishwasher air gap under your countertop is actually a pretty straightforward process. Here’s a step-by-step guide to help you get the job done:1. Begin by disconnecting your dishwasher from the power source.
Then, using a drill, create two holes in the back of your dishwasher – one for the air gap fitting and one for the drain hose.2. Next, take the air gap fitting and insert it into the first hole you drilled. Secure it in place with screws or bolts (whatever came with your particular air gap kit).
3. Now thread the drain hose through the second hole and attach it to the airgap fitting. Again, use whatever fasteners came with your kit to secure everything in place.4. The final step is to reattach your dishwasher to its power source and turn on water supply to the unit.
Once everything is hooked up, run a test cycle to make sure everything is working properly.
High Loop Vs Air Gap
There are two ways to install a dishwasher: with a high loop or an air gap. Which one you need depends on the type of sink you have.If your sink has an overflow, you can install a dishwasher with a high loop.
The high loop is a drain line that goes up and over the edge of the sink, then back down to connect to the dishwasher. This type of installation prevents dirty water from backing up into the dishwasher.If your sink doesn’t have an overflow, you’ll need to install an air gap.
The air gap is a small fitting that goes on top of the sink and has two hoses coming out of it. One hose connects to the dishwasher, and the other goes into the drain line. The air gap prevents dirty water from backing up into the dishwasher and also provides ventilation for the dishwasher so it doesn’t get too hot and cause problems with your plumbing.
Most states in the US require a dishwasher air gap, which is a small opening between the dishwasher drain hose and the sink. This prevents dirty water from backing up into the dishwasher and contaminating your dishes. If your state does not require an air gap, you may still want to install one to protect your dishwasher and dishes from bacteria.
