Understanding the mechanism

Before delving any deeper on this installation and fixing solutions. Let’s first try to understand and answer that all-important question of how does a studor vent work? This primary function of that valve is allowing air to flow into this pipe but not through it to other rooms.

In our sinks, water draining through these pipes always create a vacuum that siphons air in U-trap leaving it dry, that primary function of U-trap (also referred to as J-trap or P-trap) is that creation of an air-tight water seal that closes preventing sewer gases from escaping back up again onto this sink drain.

The studor venthole allows air onto this pipe breaking that vacuum created, ensuring there is complete preservation of that air-tight water seal in that J-trap.

Choosing the placement

It’s recommended that this air admittance valve be placed along that drain line and P-fixture, that AAV is typically mounted on one of these legs of this sanitary tee while that other leg is installed in this drain.

It’s essential to read this manufacturer’s manual if you a first-time learner so as not to worsen that problem. Also, check these local council codes to ensure you are compliant with all these rules and regulations.

Installation of the pipes

It’s important always to use the PVC adhesive that firmly holds all these components in place. You should always check on the local council guidelines about the recommended height of the AAV on top of the drain.

Attaching the AAV

Attachment of the AAV is dependent on the type and styling of the fitting. The AAV can either be glued or screwed depending on your style and preference. If you have not contracted an expert, you can look up the manufacturers’ guidelines or directions to ensure you have the correct set-up.


In some areas, some of the local council codes allow the installation of AAV as secondary ventholes. If this is the case, you should be able to continue with your installation as the sink has a venthole that’s not fully functional.


Always avoid violation of local building regulation code before installation of AAV. If it’s not permitted, you’ll require to secure the services of a plumber to cut into the walls and repair the vent.
