Which device is commonly used to isolate a section of piping for maintenance?

• A. Cleanout
• B. Vent pipe
• C. Manhole cover
• D. Sump pump

Answer: (A)

A cleanout provides a ready access point into a sewer line for maintenance work. It’s a short opening with a removable cap that lets you insert a snake or other cleaning tool to clear blockages, and the cap can be in place to isolate that section during servicing. This purpose-built access makes it the go-to device when you need to service or isolate a portion of piping without tearing into the system. Vent pipes are for letting sewer gases escape and don’t offer a means to access or isolate a line. A manhole cover gives access to the sewer system but isn’t specifically used to isolate a section for maintenance. A sump pump removes accumulated water from a pit and isn’t used for isolating piping.
