Which device provides access to a pipeline for inspection and cleaning?

• A. Cleanout
• B. Vent pipe
• C. Gate valve
• D. Tees or lateral

Answer: (A)

Access points are needed in sewer lines to inspect and remove blockages without digging. A cleanout is specifically designed for this purpose—a short pipe with a removable cap that lets you insert rods, cleaning tools, or a camera for inspection. It’s placed where blockages are likely or where the line changes direction to provide a convenient entry point. A vent pipe only releases gases, a gate valve controls flow, and tees or laterals are junctions, not entry points for cleaning.
