Air admittance valve under sink. Since I plan to use an Air Admittance Valve for the sink with a garbage disposal is the AAV the same thing as having an Air Gap deviceor do I need both.

Air admittance valves are operated by gravity. An air admittance valve AAV sometimes called an auto vent is a device attached to the fixture drain line. An Air Admittance Valve is a 1-way valve designed to allow air to enter the plumbing drainage system when negative pressures develop in the piping system.

How to install air admittance valve under the sink in under 5 minutes. It is for one-way mechanical vents that are used in a plumbing system and it totally eliminates the need for a conventional roof and pipe venting penetration. When water and waste move down a drain line it creates negative air pressure in the pipe.

This negative pressure lifts the sealing washer and lets air in which allows the waste to drain away freely. Air Admittance Valves aka Studor vents are negative-pressure-activated one-way mechanical valves. Oatey Sure-Vent AAVs are available in four sizes ranging from 8 Stack24 Branch DFU to 160 Stack500 Branch DFU.

How an AAV worksWhen a plumbing fixture is operated negative pressure causes the AAV to open allowing air to enter and equalize the pressure in the system. Please type the text you see in the image into the text box and submit. Superior engineering along with stringent quality standards ensure unmatched performance.

It has a mechanism that opens up to admit room air into the drain under the force of the negative pressure caused by water flowing through the drain. When the negative pressure ceases the sealing washer falls back in place. Get it as soon as Wed Sep 1.
