What is the term for any connection from the vent stack?

The term for any connection from the vent stack is referred to as a branch vent. A branch vent serves as an extension of the main vent stack and connects individual fixtures to the vent system, allowing for the safe release of gases and odors while maintaining proper pressure within the drainage system. This connection is crucial in preventing the siphoning of water from traps and ensuring that waste systems function effectively.

In plumbing design, the branch vent plays a significant role in facilitating air movement through the piping system. It ensures that air can enter the drainage system at designated points, helping to equalize pressure and avoid potential blockages or backpressure issues. By design, branch vents help maintain overall efficiency and performance of the plumbing venting system.

Understanding the role of a branch vent in plumbing is essential for effective system design, which ultimately impacts drainage performance and compliance with plumbing codes.
