An individual vent can vent a maximum of how many traps or trap fixtures as a common vent?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

An individual vent can serve as a common vent for a maximum of two traps or trap fixtures. This is in accordance with plumbing codes, which are designed to ensure proper venting for sanitary drainage systems. The purpose of the vent is to allow air to enter the plumbing system, which helps to maintain atmospheric pressure and allows wastewater to flow smoothly without creating vacuum conditions that could cause traps to siphon dry. By limiting the number of traps or fixtures that can be connected to an individual vent to two, the system helps to reduce the risk of inadequate venting, which can lead to drainage issues, odor problems, and potential backflow conditions. Proper venting is essential for maintaining the function and safety of residential plumbing systems.
