Which term is defined as designed for inserting cleaning tools, not for personnel entry?

• A. Outfall Line
• B. Cleanout
• C. Gravity Main
• D. Inverted Siphons

Answer: (B)

In sewer and drainage systems, some components are built specifically to provide access for maintenance tools rather than for people to enter the line. A cleanout is a short section of pipe with a removable cap that allows a plumber to insert cleaning tools, like a drain snake or auger, to clear blockages or inspect the line. It’s designed for tool insertion and maintenance access, not for personnel entry, because entering a sewer line requires strict safety measures due to confined spaces, hazardous gases, and limited oxygen. The other terms describe parts with different roles: an outfall line is where wastewater exits to a receiving body, a gravity main is the main sewer line that relies on gravity to move waste, and an inverted siphon is a structure used to carry flow beneath obstacles or changes in elevation. Therefore, the term that fits the description is cleanout.
