Fresh water tank flows out drain hose

What part of Indiana do you live in? Maybe someone who lives close to you can help you if you can’t figure it out.

Every bit of water I put in the tank runs out. The camper was parked for over a year and I had no issues. Yesterday, I pulled it home but due to the weather, I can't get outside to check it out. I am confused as to why this is happening all of a sudden. It was winterized until last Sunday. I may just do as Terryallen said and block off the hose... One thing I have noticed is that when the tank is overfilled, it does not pour out of the fill tube, it drains from this hose under the camper.

Does it stop? If it’s the overflow drain it will drain if it’s over filled or you park on an incline.

Or a drain valve was left open from winterization?

Need more info.

I'm new to rv's and I don't know why my fresh water tank just runs the water out the drain under my Coachmen Catalina. In the past, water overflowed from this hose when the tank was overfilled. The does not seem to be any leak under the camper, just from the drain hose. Any help would be appreciated. Thanks

Put a stopper in it. Mine has plugs that screw in.
