An air admittance valve, also known as a cheater vent or AAV, is a one-way valve that allows air to enter the plumbing system and equalize pressure, preventing siphoning and backflow of sewer gases. It is typically installed under the kitchen sink in homes with a closed drainage system, where there is no vent pipe connected to the roof. So why do you need one? Let's find out.What is an Air Admittance Valve and Why Do You Need One?

Installing an air admittance valve under your kitchen sink is a relatively simple process that can be done in a few steps. First, make sure your sink is properly connected to the drain and there are no leaks. Then, locate the stud where you want to install the valve and mark the center. Use a drill to create a hole in the stud and insert the valve, making sure it is securely in place. Finally, connect the valve to the sink's drainpipe and you're good to go.How to Install an Air Admittance Valve Under Your Kitchen Sink

The Role of Air Admittance Valves
When designing a kitchen sink, it is important to consider all the components that make up the plumbing system. One crucial element that often goes unnoticed is the air admittance valve. This small but mighty device plays a vital role in maintaining a functional and efficient plumbing system, specifically in the kitchen.
An air admittance valve, or AAV, is a one-way valve that allows air to enter the plumbing system but prevents it from escaping.
This valve is typically installed under the kitchen sink and serves as a venting alternative to traditional vent pipes that run through the roof. AAVs are particularly helpful in situations where installing a vent pipe is not feasible, such as in multi-story homes or buildings with complex plumbing layouts.
The Benefits of Air Admittance Valves
One of the main benefits of using an air admittance valve under the kitchen sink is that it helps prevent sewer gases from entering the home.
This not only protects the health and safety of the household occupants, but also prevents unpleasant odors from permeating the kitchen.
AAVs also help maintain proper pressure in the plumbing system, preventing issues such as slow drainage and gurgling noises.
In addition, the use of AAVs can save time and money during the construction or renovation process. Installing traditional vent pipes can be a time-consuming and labor-intensive task, especially in complex plumbing systems. AAVs, on the other hand, can be easily installed by a plumber or even a knowledgeable homeowner. This not only saves on labor costs but also eliminates the need for cutting holes in the roof for vent pipes.
Considerations for Installing an Air Admittance Valve

When incorporating an air admittance valve into a kitchen sink design, there are a few things to keep in mind.
First and foremost, it is important to follow local building codes and regulations.
While AAVs are generally accepted and approved by most plumbing codes, there may be specific requirements or restrictions in certain areas.
Additionally, the location and installation of the AAV should be carefully considered. The valve should be placed at least 4 inches above the drain and should be easily accessible for maintenance or replacement. It is also recommended to install a secondary AAV in case the primary one fails.
Conclusion
In conclusion, while often overlooked, air admittance valves play a crucial role in the design of a kitchen sink and the overall plumbing system.
Not only do they ensure the health and safety of the household, but they also provide a more efficient and cost-effective alternative to traditional vent pipes.
By understanding the benefits and considerations of using AAVs, homeowners and designers can create a functional and effective plumbing system that meets all building codes and regulations.
