List of featured suppliers of AIR ADMITTANCE VALVES Waste on Building Products Index

Air admittance valves are devices that allow air to flow into a plumbing system to prevent vacuum and backflow of waste. They are commonly used in areas without direct access to vent pipes, such as basement bathrooms, and are designed to minimize the risk of foul odors and bacterial growth. The valves are typically installed at the end of a waste pipe and use a spring-loaded diaphragm to regulate airflow.
