There are two types of dishwasher high loops: those with an air gap and those without. The air gap is the most common type, as it helps to prevent backflow from the dishwasher into the home’s water supply. However, some local building codes require a high loop without an air gap.
Either type of dishwasher high loop will keep your dishes clean and your family safe from harmful bacteria.
There are two different ways that dishwashers can be installed: with a high loop or an air gap. Which installation method is better depends on your specific needs and preferences. Here, we’ll compare the two installation methods so you can make an informed decision about which one is right for you.
A dishwasher high loop is typically installed under the kitchen sink. This installation method requires that the dishwasher be connected to the sink’s drain line. A high loop ensures that dirty water from the dishwasher will not be able to backflow into the clean water supply lines.
An air gap, on the other hand, is installed above the countertop or in another location where it will not be obstructed by cabinetry. An air gap doesn’t require a connection to the drain line and instead relies on gravity to keep dirty water from flowing back into the dishwasher.So, which installation method is better?
It really depends on your needs and preferences. If you’re concerned about preventing dirty water from contaminating your clean water supply lines, then a high loop is probably a good choice for you. However, if you don’t mind sacrificing a little bit of counter space for an easier installation, then an air gap might be a better option.
Dishwasher High Loop – What is it and what does it do?
Is a High Loop As Good As an Air Gap?
If you’re wondering whether a high loop or an air gap is the better option for your home, there are a few things to consider. First, let’s define what each of these terms mean. An air gap is simply a space between your dishwasher drain and your sink’s P-trap.
This prevents dirty water from backflushing into your dishwasher. A high loop, on the other hand, is a bit more complicated. It involves running your dishwasher drain hose up above the level of your sink and then attaching it to the underside of your countertop.
This creates a “loop” that prevents dirty water from backflushing into your dishwasher.So, which is better? Well, it depends on your specific situation.
If you have a garbage disposal installed in your sink, an air gap may be the better option since it will prevent any food scraps from clogging up your dishwasher drains. On the other hand, if you don’t have a garbage disposal, a high loop may be the better choice since it’s less likely to become clogged with food debris over time. Ultimately, it’s up to you to decide which option is best for your home!
Does Dishwasher Need High Loop for Air Gap?
Most dishwashers come with an air gap already installed. However, if your dishwasher does not have an air gap, you will need to install one. An air gap is a device that is installed between the dishwasher and the sink drain.
It allows air to enter the dishwasher so that water can be drained properly. without an air gap, water can back up into the dishwasher and cause problems.
Why Does a Dishwasher Need a High Loop?
If you have a dishwasher, you’ve probably noticed a high loop of tubing running from the dishwasher’s drain connection to the garbage disposal or air gap. This is called a “high loop,” and it’s required by most local building codes. The purpose of the high loop is to prevent dirty water from siphoning back into your dishwasher.
Siphoning occurs when water flows backward through a pipe due to a change in pressure. When dishes are being washed in your dishwasher, water is forced out of the machine through the drain line. If there was no high loop, this outgoing water could potentially siphon back into your dishwasher if there was a drop in pressure (such as when someone flushes a toilet).
The high loop prevents this by creating an obstruction that water must flow around, meaning that it can only flow in one direction – out of the dishwasher.So why isn’t the high loop required for all plumbing fixtures? Well, other fixtures such as sinks and showers are typically installed higher than floor level, which means they already have enough elevation to prevent siphoning.
Dishwashers, on the other hand, are usually installed at floor level or below, so they need that extra boost from the high loop.If you’re ever unsure whether or not your dishwasher has a properly functioning high loop, just take a look inside the tub after a wash cycle has completed. There should be no standing water remaining – if there is, it means that dirty water has somehow made its way back into your clean dishes!
Do All Dishwashers Need an Air Gap?
If your dishwasher came with an air gap and you install it, great! If not, don’t worry. An air gap is not required by most local building codes.
The air gap is there to prevent dirty water from your sink from being siphoned back into the dishwasher. If you live in an area with very high water pressure, or if your dishwasher drains into a garbage disposal, then you probably need an air gap.

Is a High Loop As Effective As an Air Gap
If you’re wondering whether a high loop or an air gap is more effective at preventing backflow, the answer may surprise you. Both methods are equally effective when installed correctly. So, what’s the difference between the two?
A high loop is typically installed under a kitchen sink. The idea is that water flowing out of the faucet will create enough pressure to force any contaminated water in the pipes back up and away from the drinking water supply. An air gap is simply a space between your plumbing fixtures and your home’s drinking water supply.
This provides a physical barrier that prevents contaminated water from ever reaching your tap water.So, which one should you choose? If you’re concerned about aesthetics, a high loop may be the way to go since it’s hidden under your sink.
But if you want peace of mind knowing that there’s an extra layer of protection between your drinking water and potential contaminants, an air gap is the way to go.
Dishwasher High Loop California
If you’re in the market for a new dishwasher, you may be wondering if you need to install a high loop. In California, all dishwashers must have a high loop installed. This is because the state has adopted the Uniform Plumbing Code, which requires that all dishwashers have a minimum clear water supply line of 27 inches.
The high loop accomplishes this by bringing the water line up and over the edge of the sink, preventing backflow into your dishes. While it may seem like an extra step, installing a high loop is actually quite simple and can be done in just a few minutes.
Dishwasher Air Gap
If you have a dishwasher, you probably have an air gap. But what is it and what does it do? An air gap is a small device that helps to prevent dirty water from your dishwasher from backing up into your home’s clean water supply.
It’s usually installed under your kitchen sink, near the dishwasher.The air gap has two hoses: one that goes to the dishwasher and one that goes to the drain. When the dishwasher is turned on, water flows through the first hose and into the dishwasher.
The second hose allows air to enter the dishwasher, which prevents dirty water from flowing back up into your home’s clean water supply.If you don’t have an air gap, or if it’s not installed properly, dirty water can back up into your home through the dishwasher’s drain hose. This can contaminate your home’s clean water supply and lead to health problems.
Conclusion
If you’re wondering whether to install a dishwasher high loop or air gap, there are a few things to consider. A dishwasher high loop is typically required by building codes, while an air gap may be recommended by the manufacturer of your dishwasher. Either way, both options will help prevent dirty water from backing up into your dishwasher.
