## Overview

The 20340 Mini-Vent Air Admittance Valve by Studor is a compact, high-capacity plumbing valve designed to prevent water trap seal loss and block sewer odors without roof venting. Compatible with 1.5" and 2" piping, it operates reliably across extreme temperatures (-40°F to 150°F) and features an exclusive vermin protection system, making it ideal for residential and commercial single or grouped fixture ventilation.

## Description

Product 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. From the Manufacturer The Mini-Vent is a solution for any single fixture and for a group of fixtures connected to a single branch, i.e. branch ventilation in residential/domestic and commercial applications. It can also be used with other Studor AAVs to complement larger and high rise building drainage systems and is ideal for all single fixtures: washing machines, toilets, sinks, baths and showers, etc.

Review: Works great - Works like it should. been installed for a few months now and no issues.
Review: Fixed our problem - Quality product and brand. Previously, we purchased a off brand, cheaper vent from our local hardware. That valve only worked 50% and for 6 months. This valve immediately allowed the proper air flow which resulted in drain emptying. Easy installation.

## 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.
