Where does this intake go?

I have a (new to me) 2012 Avalanche 341TG. I'm not sure what the intake circled in red is for. A little help?

Does the black tank flush in the blue circle flush both tanks or just the front one?

It's probably the port to ingest antifreeze into the trailer plumbing during winterization. Attach a short piece of hose, turn the valve below it to winterize, put the hose into a gallon of antifreeze, turn on the pump and it'll draw the antifreeze into the system.

It will probably just flush the front tank. A single garden hose would hardly carry the volume/pressure to properly operate two tank flushers.
