An air gap drain is a type of drainage system that uses a physical barrier to prevent contaminated water from entering the home. The most common type of air gap drain is the one that is installed under the kitchen sink. This type of air gap drain has a small hole in the bottom of the sink that leads to a trap. The trap is then connected to a pipe that goes to the outside of the house.
There are two main types of air gaps, horizontal and vertical. Horizontal air gaps are typically used in residential applications, while vertical air gaps are more commonly seen in commercial settings. There are several benefits to using an air gap drain over other types of drains, such as:
-They prevent cross contamination: Air gaps provide a physical barrier between clean and dirty water, preventing contaminants from coming back into your home through the drainage system.
-They're easier to clean: Since there's no direct connection between dirty and clean water, it's less likely for clogs or buildups to occur in an air gap drain. And if they do happen, they'll be much easier to clear out than in a traditional drainage system.
-They're required by code in some areas: In some jurisdictions, having an air gap drain is actually required by law - so if you're planning on selling your home or business, it's something you'll need to take into consideration.
