2022年5月26日 · One solution is an air admittance valve or AAV. These valves are gravity-operated devices that respond to the negative pressure of draining water and open to let air in. Then gravity closes the valve, keeping sewer gases out of the room. Depending on the valve and the size of the vent, AAVs can support one or multiple vent lines.

AAVs can be used to service an individual fixture or several - what's permitted depends on local code, and the model being used - units like the Redi-Vent can accommodate a mere 20 DFUs (Drainage Fixture Units) while large units like the Maxi-Vent can handle up to 500 DFUs.

When properly installed, an air admittance valve in the system is equivalent to an open vent pipe having the same cross-sectional area as any other vent. Such open air vent is recommended, not required, to be located as close as possible to the connection between …

Oatey® offers a wide range of Sure-Vent® Air Admittance Valves to enable installation in virtually any application. Superior engineering along with stringent quality standards ensure unmatched performance. Complies to ASSE Standard 1050 and 1051 and IAPMO listed sizes.

An Air Admittance Valve (AAV), which you may also hear referred to as a Studor Vent, Studor AAV or Mini Vent, is a one-way mechanical valve that is installed locally at the site of a plumbing fixture, allowing proper venting to occur without a connection to a …

Air Admittance Valves (AAV) — Oatey ®Sure-Vents® — are mechanical devices installed to a plumbing fixture, replacing a secondary vent. These valves allow one-way ventilation, removing the need to connect to an existing venting system or run a separate, potentially unsightly ventilation system.

2022年11月29日 · An Air Admittance Valve (AAV), which you may also hear referred to as a Studor Vent, Studor AAV or Mini Vent, is a one-way mechanical valve that is installed locally at the site of a plumbing fixture, allowing proper venting to occur without a connection to a larger venting system and stack vent.

This vent is designed to open when the plumbing fixture (s) it serves are draining, thus allowing air to enter the drain waste vent system. The Studor vent AAV closes (by gravity alone, no springs), when there is no wastewater flowing through the system, thus preventing sewer gas from passing up the drain or vent into the building.

This Oatey Sure-Vent PVC Air Admittance valve is handy for when you don’t want to spend the time and money running a vent all the way through the roof. What this valve is designed to do …

2024年1月31日 · Compared to passive vents, AAVs offer several benefits: Eliminate need to penetrate roofs – No vent stacks through the roof are required when using AAVs. This makes them ideal for use in multi-story buildings. Reduced risk of leaks – With no vent penetrations needed through the roof, AAVs eliminate the potential for leaks from vent pipe seals.
