1-1/2″-2″ Stack Vent

STUDOR Redi-Vent Air Admittance Valve – 1-1/2″ to 2″ with PVC Adapter

The IPS STUDOR Redi-Vent is a mechanical air admittance valve engineered for use in venting single fixtures or bathroom groups in residential and commercial applications. Designed for 1-1/2″ and 2″ piping, it allows air to enter the drainage system under negative pressure conditions, preventing the need for a traditional open pipe vent to the roof.

Product Highlights

• Application: Designed to vent individual fixtures or bathroom groups up to 20 Drainage Fixture Units (DFUs)
• Operating Mechanism: One-way valve opens under negative pressure and closes after equalization to prevent sewer gas escape
• Size Range: Compatible with both 1-1/2″ and 2″ nominal pipe sizes
• Material: Includes PVC adapter; body and internal components constructed to resist mechanical and chemical wear
• Install Location: Suitable for use in vertical stacks or branch applications per local code

Key Features

• Compact Housing: Allows installation in confined spaces, including under-sink cabinets and wall cavities
• Vermin Guard: Integrated design prevents pests from entering through the valve mechanism
• Gravity-Close Design: Valve seals automatically after pressure equalization, reducing the risk of foul odor escape
• No Roof Penetration Required: Eliminates the need for extending vent piping to the exterior
• Code Accepted: Listed and approved for use in accordance with IPC and UPC where AAVs are permitted

Installation Overview

The Redi-Vent installs directly onto DWV piping using the included PVC adapter. Proper orientation and minimum required clearances must be followed to maintain performance and code compliance. Always verify local code acceptance of air admittance valves before use.
