Help identifying water line drains

[ifrpilot99]

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?

Thank you

Steve

Looks to me the two you have unidentified are the hot and cold low point drains. I cannot help with the one that you had tagged as the low point drain.

You have the common low point drain with tag back with the vent, some reason must be a pipe elevation, they have separate hot and cold water drains to the right. Drain all for proper draining if you must winterize.
