The Professional Solution to a Common Plumbing Headache.
As a Master Plumber with over 25 years in the field, I can tell you that 90% of "slow drain" calls for sinks that aren't clogged are actually venting problems. When water goes down the drain, air needs to come in to replace it. Without proper venting, your plumbing creates a vacuum, causing gurgling sounds and slow drainage. The Oatey Sure-Vent® Air Admittance Valve (AAV) is the simple, reliable, professional solution to this common issue.
Why It's the Gold Standard for Modern Venting
Traditionally, every plumbing fixture needed a vent pipe that ran all the way through the roof—an expensive and labor-intensive process, especially for kitchen islands. The Sure-Vent® AAV is a brilliant piece of engineering that solves this. It's a one-way valve that stays closed, sealing off sewer gas. The moment you drain your sink, the negative pressure sucks the valve open, allowing air to rush in and break the vacuum. The drain flows fast and silent. As soon as the draining stops, the valve instantly closes, forming a perfect seal. This is a code-approved, trusted device that makes plumbing renovations easier and existing systems work the way they were always meant to.
Installation Guidelines
- Identify the vertical drain line after the P-trap under your sink.
- Cut the drain pipe and install a sanitary tee fitting, ensuring the new vertical branch is above the fixture's flood level rim.
- Glue the included PVC adapter to a short piece of PVC pipe and insert it into the tee.
- Hand-tighten the Sure-Vent AAV onto the adapter's threads. **Do not use pipe dope or tape.**
- Ensure the valve is in an accessible location with open air flow (e.g., not sealed inside a wall). Professional installation is recommended.

Frequently Asked Questions
Where do I install this valve?
Typically, an AAV is installed on a vertical drainpipe above the P-trap of a fixture (like a sink) and must be located in an accessible area with free air flow. It is the most popular solution for venting kitchen island sinks where a traditional vent through the roof is not possible.
Is this approved for use in my area?
Oatey Sure-Vent AAVs are compliant with major plumbing codes (ASSE 1050 and 1051). However, local codes can vary. It is always best practice to check with your local plumbing authority to ensure AAVs are permitted for your specific application.
