The hose coming down from the tank is actually the overflow because it is coming out of the top of the tank down through the floor. I ended up cutting one of the hoses out of the tank to try to siphon it but I didn't have any luck with that. I did however find that someone I'm not sure who, maybe the trailer came like this but there was a hole drilled through the floor wide enough to fit the hose so I guess that's how people have been dreaming the tank in the past. Water is draining through there now, will replace the faucet after I run a new hose throughout the trailer.
