Low point drain

[captain Morgan]

Where are the low point drains on a Sprinter 299ret (2015)?

They could be either red / blue lines or white lines. They also could have vales on them or just caps that will unscrew to drain. While I dont know exactly where your low point drains are, they will be sticking out of the coroplast and maybe even surrounded with spray foam or covered with foam. Good luck in your search...
