When it comes to installing a dishwasher, one of the most important considerations is ensuring that the drain system is functioning properly to prevent water from backing up and causing damage to your home. This is where the concept of an air gap comes into play.
What is an Air Gap and Why Do You Need It?
An air gap is a safety device that is installed between the dishwasher and the drain system. Its purpose is to prevent dirty dishwater from contaminating the clean water supply and to protect against backflow. It acts as a barrier between the two systems, allowing air to flow freely and preventing water from flowing back into the dishwasher. In many states it is necessary to install an air gap if you have a dishwasher installed.
Types of Air Gaps
There are two main types of air gaps: standard and high-loop. Both types of air gap plumbing keep your dishwasher from accidentally siphoning dirty water back from the drain. Standard air gaps are typically larger and sit on top of the countertop next to the faucet. High-loop / under counter air gaps are created by looping the dishwasher hose up to the underside of the counter before it hits the drain, and are completely out of site.
What To Do If Water Comes Out Of The Air Gap
If water is coming out of the air gap, it is a sign of a clogged dishwasher or a blocked drain line. If your air gap is leaking, it is important to address this issue as soon as possible to prevent flooding or other water damage. You can try running hot water through the dishwasher for a few minutes to clear the clog or you can use a bottle cleaner brush to try unblock the drain line.
How To Install An Air Gap
Installing an air gap is relatively simple and can be done in a few steps. First, turn off the water supply to the dishwasher. Next, connect the dishwasher drain hose to the air gap inlet. Then, connect the air gap outlet to the garbage disposal or sink drain. Finally, turn the water supply back on and test the air gap to make sure it is functioning properly.
How to Install an Air Gap Under the Countertop
High Loop air gaps can be installed under the countertop by following these steps. First, locate the hole where the air gap will be installed. Next, insert the gasket into the hole and secure it in place. Then, attach the air gap to the gasket and tighten the nut to secure it in place. Finally, connect the dishwasher drain hose to the air gap inlet and the air gap outlet to the garbage disposal or sink drain.
How To Connect Dishwasher To Garbage Disposal Without An Air Gap
If you want to connect your dishwasher to the garbage disposal without using an air gap, you can use a high loop installation. This involves running the dishwasher drain hose up to a level higher than the top of the disposal unit and then back down to the disposal. This creates a loop that prevents backflow and meets code requirements.
Dishwasher Air Gap Alternatives
If you don't have room for an air gap or don't want to use one, there are alternative options available - in some dishwashers check valves may already be in place to prevent the tub water from re-entering the dishwasher. Another option is to use a dishwasher air gap kit that includes a check valve. Lastly you can opt to install a backflow prevention device in the drain line, which provides the same protection as an air gap.
In conclusion, air gaps play an important role in the installation of dishwashers to prevent water damage and protect against backflow. It's important to understand the different types of air gaps, how to install them, and alternative options available.
