What is the minimum vent pipe size from a sump or receiving tank for a sewage pump system?

• A. 1/2 inch
• B. 2 inch
• C. 3 inch
• D. 4 inch

Answer: (A)

In a sewage pump system, proper venting is essential to facilitate the safe and effective operation of the system. The minimum vent pipe size for a sump or receiving tank serves to ensure adequate airflow, allowing gases to escape and preventing pressure buildup that could disrupt the system's function. A vent pipe that is too small can lead to backpressure, which may cause the sewage pump to operate inefficiently or fail. In this context, the correct answer is a minimum vent pipe size of 2 inches. This size is typically required to maintain proper ventilation, especially in systems that handle sewage, as they can produce significant levels of gas. The broader diameter allows for sufficient air exchange, reducing the risk of blockages and operational failures that could occur with smaller vent openings. Proper vent sizing, according to plumbing standards, is vital for both performance and safety in sewage management systems. Choosing a lesser size, such as 1/2 inch, would not meet the necessary requirements for effective venting and could compromise the system's integrity. Thus, adhering to the standard of 2 inches ensures compliance with the plumbing code and operational efficiency.
