In sewer maintenance, what is a pig?

Explanation:
In sewer maintenance, a pig is a device placed into a sewer line and forced through the pipe to clean and clear it. It’s typically a ball or disc-like plug that is propelled by air or water pressure, scrubbing the pipe walls and pushing debris ahead to restore flow. This is why the best description is a ball forced through a sewer line. Other options describe different tools and equipment that aren’t what a pig is.
