How to Install an AAV Under Sink: A Step-by-Step Guide

Installing an Automatic Air Vent (AAV) under your sink can be a straightforward DIY project, but it requires careful planning and execution to ensure proper installation and functionality. In this guide, we'll walk you through the step-by-step process of installing an AAV under sink, highlighting key considerations and best practices to keep in mind.

Pre-Installation Checklist

Before starting your installation, make sure you have the following materials and tools:

• AAV unit
• Drain assembly
• Valve stem
• Tools (e.g., adjustable wrench, pliers, screwdriver)
• Faucet shut-off wrench

Additionally, ensure you have a clear understanding of the following:

• Understand the AAV unit's specifications and installation requirements.
• Know the location of the drain and water supply lines.
• Identify any nearby obstacles or constraints (e.g., plumbing, electrical components).

Shut Off the Water Supply and Drain the P-Trap

Locate the shut-off valves for the hot and cold water supply lines and turn them clockwise to shut off the water supply.

Next, disconnect the P-trap from the drain assembly. This will allow you to access the area where you'll be installing the AAV.

Mount the AAV Unit

Locate the mounting bracket on the AAV unit and attach it to the sink or surrounding area using the provided screws or clips.

Make sure the bracket is securely fastened to prevent any movement or vibration that may affect the AAV's performance.

Connect the Drain Assembly

Attach the drain assembly to the AAV unit, following the manufacturer's instructions.

Be sure to tighten all connections securely to prevent leaks.

Install the Valve Stem

Insert the valve stem into the AAV unit, ensuring it's securely seated.

Tighten the valve stem to the specified torque to prevent any leaks or damage to the AAV unit.

Reconnect the P-Trap and Water Supply Lines

Reattach the P-trap to the drain assembly, making sure all connections are secure and watertight.

Reconnect the water supply lines to the shut-off valves, tightening them securely to prevent leaks.

Test the AAV Unit

Turn on the water supply and check for any leaks around the AAV unit and drain assembly.

Check the AAV unit's operation by allowing air to escape through the valve stem and observing the AAV unit's performance.

Additional Tips and Considerations

When installing an AAV under sink, consider the following:

Install the AAV unit in an area with easy access for maintenance and repairs.

Ensure the AAV unit is installed at a level to prevent water from accumulating in the unit.

Use the correct type of gasket or seal to prevent leaks around the valve stem and drain assembly.
