Which piping component is used to minimize sediment buildup in pipelines?

• A. Elbow fittings
• B. Tees
• C. Return Bends
• D. Caps

Answer: (C)

Sediment tends to settle in parts of a piping system where flow is sluggish or there are dead-end pockets. A return bend creates a looping, smoother path that encourages water to keep moving and allows solids to be carried toward a flushing or drain point, reducing areas where sediment can settle. This smoother, continuous flow minimizes stagnant zones better than a cap (which creates a closed end), tees (which introduce branches and potential dead spaces), or a standard elbow (which still can create eddies and pockets). So, the component most effective at minimizing sediment buildup is the return bend.
