Did you winterize it or someone else? If someone else, look for the cap to this drain behind the outside door for the water heater.

Perhaps you are looking at a vent hose and the tank is full.

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

The drain under the Coachman is a low point drain or fresh water tank drain. Its sole purpose is to drain the tank. It has been left open. Find its valve and close it. The vent hose is beside the opening to fill the tank. The vent hose opening is higher than the water tank to prevent siphoning.

JK, I have two hoses underneath and at the back marked as low point drains. The hose that drains my tank is forward of that and also has another hose next to it that has a valve and plug in it.

Check to see if the plug is only hand tight in the valve, with a valve you don’t need the plug and they might have stuck it in there when they winterized it so it wouldn’t get lost. It should screw into your drain hose.
