I would consider all of the drain pipes to be "sewer lines". For a house, I
would consider the "main line" to be all piping from the street sewer into
the house up to any point where it branches into two similar sized pipes.
Anything from that point I would consider "branch lines" as well as any
smaller lines which connect to the "main line". However, these terms are not
necessarily standard for all users. Have the plumbers show you exactly where
the pipes have been cleaned and where they have not.
