Help identifying water line drains
I have four water line drains near the low water point drain line and what I believe is the fresh water tank overflow/air intake. Although I am confident I have correctly identified the low water point drain, the fresh water tank drain and the air intake/fresh water tank overflow, there are two lines that I have no idea what purpose they serve.
My rig is a 2013 Georgetown 351DS. I have attached a picture for reference. If anyone can determine the purpose of these two lines, I would appreciate it.
Also, I have yet to fill the fresh water tank. Am I correct in assuming that I can fill the tank until water is expelled from the overflow/air intake line?
