Which access device is essential for removing solids and clearing stoppages in a sewer line?

• A. Junction Boxes
• B. Catch Basin
• C. Cleanouts
• D. Backflow Preventers

Answer: (C)

Access to the sewer line for maintenance is what this item provides. A cleanout is a dedicated access point—a capped fitting that opens the interior of the pipe—so you can insert a sewer rod or hose, push or pull out solids, and break up or remove blockages. Cleanouts are placed where stoppages commonly occur or where the line changes direction, making it practical to reach the flow path without digging up large sections of pipe. The other devices aren’t used for clearing blockages: junction boxes are for electrical or control connections, catch basins collect surface water and debris but aren’t entry points for clearing the sewer line, and backflow preventers stop sewage from backing up but don’t provide access for cleaning.
