Studor 20380 Recessed Air Admittance Valve Box & Grill — Conceal AAVs in Cabinets

Overview

When space inside an existing cabinet prevents a traditional AAV installation, the Studor 20380 Recessed Box provides a discreet, code-friendly solution. The low-profile enclosure hides valves behind a clean, flush grille while keeping access for testing and service simple. This approach helps maintain a tidy interior in kitchens, bathrooms, laundry rooms, and utility spaces without compromising function.

Key features

The recessed box is designed to work with popular AAV models and standard drainage lines, offering flexible installation choices for a range of projects.

• Works with Mini-Vent, Tec-Vent, or Redi-Vent air admittance valves
• Connects to 1-1/2 inch or 2 inch ABS or PVC piping
• One-piece construction includes a built-in mounting flange, eliminating the need for extra framing or support in the stud bay
• Snap-on grill conceals the AAV from view while allowing accessibility as required by code

Size and finish are designed for a clean, unobtrusive appearance. The white box (with grill) measures 6-5/8 inches wide by 8 inches high, offering a compact footprint that works well in tight spaces.

Accessibility and testing

An integral test cap is included, providing a convenient, industry-first means to verify valve operation without disassembly. This feature supports straightforward inspections and routine checks while preserving a neat, code-compliant look.

Usage scenarios and benefits

Possible benefits in real-world installations include a more streamlined cabinet interior, flexible placement options, and a straightforward path to code-compliant ventilation for select valve models. Results vary by project, but many installations benefit from a discreet enclosure that keeps valve components accessible from the front and out of sight.
