What is used to allow access to sewers to remove solids that cause stoppages?

• A. Cleanouts
• B. Junction boxes
• C. Air Test
• D. Backflow Preventers

Answer: (A)

Cleanouts are the access points that let you reach the sewer to remove solids and clear stoppages. A cleanout is a capped fitting that opens into the sewer line, providing a convenient entry where you can insert a sewer rod or drain-cleaning equipment to break up or pull out solids causing a clog. They’re placed at strategic spots—where the line changes direction, at the base of stacks, or where a service lateral meets the main—so maintenance crews can clear obstructions without invasive digging. The caps must seal to keep sewer gases out and water from leaking in. Junction boxes aren’t used for cleaning sewers; they’re for electrical or communication connections. An air test is a method to check pipe integrity, not to access the line for cleaning. Backflow preventers stop sewage from backing up into the building, not for removing solids or clearing blockages.
