What is the main purpose of using flexible joints in a drainage system?

• A. To simplify installations
• B. To allow for easier access
• C. To allow for differential settlement
• D. To reduce noise

Answer: (C)

The use of flexible joints in a drainage system primarily serves the purpose of accommodating differential settlement. This is particularly important in situations where the ground conditions may change over time, such as in soil movement, shifting, or settling. When different sections of the drainage system move independently, flexible joints can absorb these changes without causing damage or stress to the pipes. This flexibility helps maintain the integrity of the system, preventing leaks or failures that could result from rigid connections where movement occurs. Furthermore, flexible joints can help to mitigate issues caused by temperature changes, which can cause materials to expand and contract. By allowing for some give, these joints enhance the durability and functionality of the drainage system over time.
