It comes from above where the black water drain connects, but is has a grease pen marking on it from the factory either FH or FW. But the fact that it seeps where the wall meets the floor, makes me this it may be wise for me to try to gain access from up top through a wall, vs. trying to drop the underbelly.
I'm not sure of the plumbing, as it seems that ALL useful information is left out of the owner manuals, (I'm not a fan of the umbrella, generalized literature they give you), but I'm wondering it water stayed in the city water line, below my bathroom, and above the mystery tank, and froze. How do you winterize the city water supply line even?
Unfortunately, it appears something, somewhere didn't get flushed with antifreeze and resulted in a freeze and break.
Also just because the leak seems to be coming from near one of the tanks, don't hold your breath that is the problem. The factory runs water lines around and on top of the tanks to get from one end of the unit to the other so it could be a line or fitting that just happens to be in that area.
As was suggested, filling the fresh water tank with antifreeze (to pump throughout the system) is not the best method to winterize. Many units have a built in antifreeze port where antifreeze can be drawn in via the pump (bypassing the fresh water tank) and for those units without that port, there are kits available that connect at the water pump that serve the same purpose.
Since you've added antifreeze to the fresh tank, you are going to need to flush the tank MULTIPLE times to get all the antifreeze out. The reason being, many of the tanks are plumbed so that not all the liquid evacuates out of the tank, leaving as much as several gallons in the tank. I suspect yours still had water in the tank when you added antifreeze so it diluted the antifreeze to the point it may not have been effective enough.
To answer your question about how you winterize the city water port... the
city water port has a check valve directly inside the connection where you attach the hose. Its function is to keep water from coming out the city water port when using the on board pump. When winterizing, you have to use a tool like a small screwdriver to depress the check valve long enough to evacuate the remaining water until antifreeze flows. Just be sure to stand off to the side when doing so or you'll wind up wearing the pink stuff.
Unfortunately, it doesn't sound like yours is going to be an easy fix.
Best of luck finding and fixing the problem(s).
