Yes, you can install a dishwasher without an air gap. However, we recommend that you consult a professional to ensure it is installed correctly.

  • Locate the nearest water source to where you will be installing the dishwasher
  • This is typically under the kitchen sink
  • Turn off the water supply at the valve and disconnect the supply line from the shut-off valve using a wrench or pliers
  • Measure the distance from the top of your dishwasher’s opening to where you will be attaching it to the water source
  • Add an extra 6 inches to this measurement to account for bends in the tubing, then cut a length of flexible tubing using a hacksaw
  • Attach one end of the tubing to your dishwasher’s inlet port using a nut and ferrule, then attach the other end of the tubing to your chosen water source using another nut and ferrule
  • Be sure to hand-tighten all connections before moving on
  • Use hose clamps or pipe tape (depending on what type of connection you have)to secure all connections, then turn on your water supply at the valve and test your dishwasher by running it through a cycle empty

Dishwasher Air Gap Alternative

If you don’t have an air gap for your dishwasher, there are alternative methods you can use to ensure your dishwasher drains properly. One method is to create a loop in the drain hose. This will allow water to drain, but will prevent it from backing up into the dishwasher.

Another method is to install a check valve in the drain line. This will allow water to flow out of the dishwasher, but will prevent it from flowing back in. Either of these methods should ensure that your dishwasher drains properly without an air gap.

Can I Replace Dishwasher Air Gap With Soap Dispenser?

If your dishwasher has an air gap and you’re having problems with it, you may be wondering if you can replace it with a soap dispenser. The answer is maybe. It depends on the model of your dishwasher and the size of the opening for the air gap.

If the opening is too small, then a soap dispenser won’t fit. But if the opening is just right, then a soap dispenser could work as a replacement for an air gap. So why would you want to replace an air gap with a soap dispenser?

Well, there are a few reasons. First, air gaps can sometimes get clogged and need to be cleaned out regularly. Second, they can sometimes leak, causing water to drip onto your countertop or floor.

And third, they can be unsightly and take up valuable counter space. So if you’re looking for a way to get rid of your dishwasher’s air gap (and all the headaches that come with it), replacing it with a soap dispenser might be the way to go!

Which is Better a High Loop Or Air Gap for a Dishwasher?

If you’re wondering whether a high loop or air gap is better for your dishwasher, there are a few things to consider. A high loop is typically installed under the counter and connects the dishwasher drain hose to the house plumbing above the sink. An air gap is installed on top of the counter and prevents dirty water from siphoning back into the dishwasher.

So, which one is better? It really depends on your needs and preferences. If you’re worried about dirty water siphoning back into your dishwasher, then an air gap is probably a good choice for you.

However, if you’re concerned about aesthetics or have limited space under your counter, then a high loop might be a better option. Ultimately, it’s up to you to decide what will work best for your home.

Do Bosch Dishwashers Need an Air Gap?

If you have a Bosch dishwasher, you may be wondering if it needs an air gap. The answer is yes, Bosch dishwashers do need an air gap. This is because they are designed to work with a specific type of plumbing system called a recirculating pump.

Without an air gap, the dishwasher would not be able to function properly.

Does Kitchenaid Dishwasher Need Air Gap?

If you have a dishwasher with a garbage disposal, you might be wondering if you need an air gap. The answer is yes! An air gap is required by most building codes when installing a dishwasher.

This is because the air gap prevents dirty water from being siphoned back into your dishwasher. The air gap also protects against clogs in your drain line. If your dishwasher doesn’t have an air gap, food and grease can build up in the drain line and cause clogs.

An airgap helps to keep this from happening by allowing water to flow freely out of the dishwasher. So, if you’re wondering whether or not you need an air gap for your Kitchenaid dishwasher, the answer is yes!


The air gap is a required part of the dishwasher installation process. It helps to prevent dirty water from recirculating back into the dishwasher. Without an air gap, your dishwasher will not work properly and could potentially cause water damage to your home.
