A relief vent is required when there are ___________________ or more branch intervals?

• A. 5
• B. 10
• C. 15

Answer: (B)

A relief vent is required when there are 10 or more branch intervals to prevent the buildup of pressure in the plumbing system. This is essential for maintaining the proper function of drainage systems and avoiding potential issues such as backflow or blockages. Branch intervals refer to the segments of a plumbing system that run horizontally and can contribute to pressure changes within the system when drainage activities occur. When there are multiple branch intervals, the likelihood of creating negative pressure increases, which can lead to sewer gases entering the building or hinder the flow of wastewater. By implementing a relief vent at the specified threshold, you ensure that air can enter the system freely, preventing any disruptions in drainage and maintaining a safe and efficient plumbing environment. This requirement is designed to uphold safety standards and operational efficiency within the plumbing code.
