What is a branch vent?

A separate waste line
A connection for fixtures
A vent connecting individual vents with vent stacks
A main vent line

The correct answer is: A vent connecting individual vents with vent stacks

A branch vent is specifically a vent that connects individual fixtures or groups of fixtures to the main vent stack, ensuring proper air circulation in the drainage system. Its primary function is to prevent the trapping of negative pressure that can lead to the siphoning of water from traps, which can cause odors and the potential for sewer gases to enter the home. By ensuring that each fixture is properly ventilated, branch vents help maintain the integrity of the plumbing system, allowing waste to flow out smoothly while simultaneously providing an exit route for sewer gases. This connection plays a crucial role within the overall venting system, linking multiple fixtures back to the larger vent stack for proper aeration. The other possible responses do not accurately describe the function or definition of a branch vent. Separate waste lines refer specifically to the drainage of wastewater and do not involve venting. Connections for fixtures, while important, do not encompass the specific duty of ventilation that branch vents provide. Lastly, a main vent line relates to a singular, larger venting system and does not account for the individual connections that branch vents facilitate.
