The vent from a pneumatic ejector system shall be _____________________.

In pneumatic ejector systems, it is crucial for the vent to be independent from other vents to ensure proper functioning and avoid potential backflow or interference with other plumbing systems. This independence allows for optimal air circulation and prevents any contaminant crossover, ensuring sanitary conditions are maintained. A dedicated vent reduces the chance of pressure imbalances that could affect the ejector's performance, leading to inefficient operation or failure to expel waste properly.

Additionally, while connecting to building vent systems may seem practical, it could lead to complications, such as potential siphoning or blocking of other critical venting requirements. Furthermore, the minimum size of the vent is important but is not the main concern; rather, the focus is on maintaining independence to promote the system's reliability and safety.
