What is required for every trap and trapped fixture in plumbing systems?

• A. Sealed
• B. Vented
• C. Unvented
• D. Accessible

Answer: (B)

For every trap and trapped fixture in plumbing systems, venting is a critical requirement. The purpose of venting is to allow air to enter the drainage system, maintaining atmospheric pressure and enabling proper drainage and the smooth flow of wastewater. When traps are vented, it helps prevent the formation of vacuums that could siphon water out of the trap, which could otherwise lead to sewer gases entering the building and creating health hazards. Additionally, venting is essential for ensuring that wastewater flows freely through the pipes without obstruction or backing up. Proper venting also helps in maintaining the integrity of the trap seal, which is crucial for keeping odors and gases from escaping into living areas. In summary, venting is a vital component of plumbing systems that supports effective drainage and sanitation.
