Most dishwashers have an air gap built in, but some states require a separate air gap to be installed. An air gap is a device that prevents contaminated water from flowing back into the dishwasher. It is usually installed under the sink and has two hoses: one that goes to the dishwasher and one that goes to the drain.
The air gap keeps contaminated water from flowing back into the dishwasher and ensures that dishes are cleaned properly.
Most states in the U.S. require that a dishwasher be equipped with an air gap, which is a device that prevents contaminated water from being siphoned back into the dishwasher. The air gap is usually installed on the countertop near the dishwasher and has two parts: a drain hose and an overflow pipe.
The purpose of the air gap is to protect against backflow, which can occur when there is a difference in water pressure between the dishwasher and the sewer line.
If there is no air gap, contaminated water could be sucked back into the dishwasher, contaminating dishes and potentially causing illness.
An air gap is not required in all states, but it is recommended by most plumbing codes. Even if your state does not require an air gap, it’s still a good idea to install one to protect your family from harmful bacteria.

Do I Need a Dishwasher Air Gap
If you’re thinking about installing a dishwasher in your home, you may be wondering if you need an air gap. An air gap is a small device that is installed between the dishwasher and the sink. It allows water to drain from the dishwasher without coming into contact with the sink.
While most local building codes don’t require an air gap, it’s a good idea to install one anyway. Here’s why:
An air gap prevents dirty water from backing up into your dishwasher.
If your dishwasher doesn’t have an air gap, dirty water can flow back into it, contaminating your dishes and causing them to come out dirtier than they went in. An air gap also protects against leaks. If your dishwasher springs a leak, an air gap will ensure that water doesn’t flow back into your sink or countertop area.
Installing an air gap is relatively simple and only takes a few minutes. You can find them at most hardware stores or online retailers. Be sure to check your local building code requirements before purchasing an airgap to make sure it meets all necessary standards.
How to Install Dishwasher Air Gap under Countertop
Assuming you have all the necessary tools and parts, installation of a dishwasher air gap is relatively easy. Here are the basic steps:
1. Turn off the water to the sink.
Find the shut-off valve under the sink and turn it clockwise to close it.
2. Disconnect the dishwasher drain hose from the garbage disposer or other drain connection.
3. Install the air gap according to manufacturer’s instructions.
This will usually involve attaching it to the countertop with screws and then connecting the dishwasher drain hose to it. Be sure to use Teflon tape or plumber’s putty on all threaded connections to prevent leaks.
4. Open the shut-off valve and turn on the water at the sink faucet nearest to where you installed the air gap, until water comes out of Dishwasher Air Gap unit (this primes your system).
You may also need to open up your Dishwasher and locate their internal shut-off valve and open that as well before turning on your water at your kitchen sink faucet (every model is different so check your manual).
High Loop Vs Air Gap
There are two ways to drain your dishwasher: high loop and air gap. So, what’s the difference? And which one is right for you?
A high loop is the most common type of dishwasher drain. It works by using gravity to pull water out of the dishwasher and into the drainage system. All you need is a few inches of clearance under your sink to install a high loop.
An air gap is a second line of defense against dirty water backing up into your dishwasher. It’s required in some areas, but not all. An air gap consists of a small hole in your countertop that’s connected to a pipe leading outside.
When water tries to back up into your dishwasher, it hits the air gap and gets forced out through the hole.
So, which one should you choose? If you live in an area where an air gap is required, then you have no choice!
But if you have a choice, we recommend going with a high loop. High loops are less likely to get clogged than air gaps, and they’re also easier to install and maintain.
Conclusion
Most states in the U.S. require a dishwasher air gap, which is a small hole or gap between the dishwasher drain and the water supply line. The purpose of this air gap is to prevent dirty water from backing up into the dishwasher. While some states have specific requirements for the size and location of the air gap, others simply require that one be present.
