I know it was not the filters leaking. I checked them first. Had two AC50's on the tank, check them and no leakes or anything, no water streams down the back of the tank. That's when I noticed the water was flowing from where the tank sits on the stand so has to be a bottom seal that blew.
Thankfully I live in old run down Apts that are actually in the middle of a remodel. Anyways this wall has sume huge gaps that you can feel cold air coming up from the crawl space. So I sent the water down there. Looked in on it they the access in the closet and all was fine. No huge puddles of water. The dirt soaked it all up.
