How to Install an Air Admittance Valve to Fix a Slow-Draining Sink
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. However ...
How to Install Secondary Venting Systems – Air Admittance Valves (AAV …
An Air Admittance Valve (AAV), which you may also hear referred to as a Sure Vent or quick 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.
