What is the term for connecting vent risers aboveground to form a single vent opening?

The term used to describe the process of connecting vent risers above ground to form a single vent opening is known as a manifold. This terminology is used in various engineering and plumbing contexts to refer to a system where multiple lines converge into one. In the case of vapor recovery systems, utilizing a manifold allows for the efficient collection and routing of vapors, as it helps minimize the number of openings needed for venting, which can regulate pressure more effectively and reduce potential leaks.

The concept of a manifold also implies a structured assembly where materials are connected in a way that maintains functionality and complies with safety regulations, which is crucial in vapor management to prevent environmental hazards. This understanding ties back to the importance of proper installation practices in vapor recovery systems, emphasizing the need for knowledge about how different components interact within the overall system.
