It sounds like your tank is already full. Do you know how to drain your fresh water tank? Open the drain valve to see if you are already carrying water. Most RV's will blow water back if they are filled too quickly, even with an air vent. They will also blow back if they are full. It does not sound like you have a blockage, because the water would not blow back at you if the line were blocked. It just would not take any water. The blow back affect is air from the tank, probably from being filled too fast.
