What does "backpressure" refer to in plumbing?

• A. Pressure from the supply side of the system
• B. Pressure when two plumbing systems are connected
• C. Pressure in the discharge side that exceeds the supply side
• D. Pressure due to a blockage in the system

Answer: (C)

Backpressure in plumbing refers to the pressure in the discharge side of a system that exceeds the pressure on the supply side. This situation can arise in various scenarios, such as when gravity or mechanical systems push fluids back into the supply lines, or when there is resistance due to pipe friction or other forces that cause backflow. Understanding backpressure is crucial for ensuring that plumbing systems operate efficiently and safely. In many plumbing applications, backpressure can lead to potential hazards, such as cross-contamination of potable water supplies or loss of pressure that affects the delivery of water. Therefore, recognizing and managing backpressure is essential for maintaining the integrity of plumbing systems and ensuring proper functionality. The other answer choices depict different concepts that, while related to pressure in plumbing systems, do not capture the specific nature of backpressure as it pertains to discharge exceeding supply pressure.
