## Overview

The 20340 Mini-Vent Air Admittance Valve with ABS Adapter is a compact, high-capacity plumbing solution designed to prevent sewer odors by maintaining water trap seals without roof venting. Compatible with 1-1/2" and 2" pipes, it operates reliably across extreme temperatures and features an exclusive vermin protection system, meeting ANSI/ASSE 1050 and 1051 standards for professional-grade ventilation.

## Description

The unique design of the Studor Mini-Vent provides plumbing ventilation to prevent the loss of water seals in traps without the need for costly roof penetration and vent piping. Studor Mini-Vent Air Admittance Valve with ABS Adapter is a one way valve used for branch or single fixture ventilation. It protects the water trap seals and does not allow sewer gases and smells to leak into the living space. When a negative pressure in the drainage pipe occurs, the valve opens to allow the entrance of air. When the pressure is balanced the Mini-Vent closes absolutely tight, so the foul air cannot escape. Fits: 1-1/2 or 2-inch x 2.625-inch vent height x 2-inch vent diameter. ABS construction with a temperature rating of -40 to 150 deg F.

## Questions & Answers

**Q: Why is this product listed under electronics > computers&accessories > networkingproducts > networkadapters > powerlinenetworkadapters**
A: If you plug this into your pc, it will free up hard drive admittance and the network will all speed up..  but the adaptor hasent been invented yet, guess the manufacturers have high hopes..

**Q: will the threads screw into a 1 1/2 threaded fitting?**
A: Yes, this screws directly into a 1 1/2" pipe threading. It also comes with an adapter for a 2" pipe.

**Q: what is life span for mini vent**
A: We just replaced two, both had replaced vents that were about 8 years old.

**Q: Are these suitable for exterior vent pipes?**
A: My understanding is they are only for use inside. They eliminate the need to connect new fixtures to the main stack.
