Filling fresh water tank 2019 airstream fresh water fill problem

[arvaterry]

When I fill fresh water tank water spews back and tank is slow to fill. Very slow. Tried smaller hose to allow air to backflow. Also checked inside trailer near water pump for any kinks or tears in fill hose to fresh water tank. It all looked good. Why does my airstream not fill properly and water backs out like crazy no matter what the pressure is of the water going in?

Did you check the vent line?

I viewed vent line and looks clear. Should I just remove
Screen and try again to fill?

I mean remove screen on vent line? I thought about removing screen and buying a plug to
Fit the vent hose and remove when filling. Then plug up in between fills.

Go slower...the vent is too small.
Filling ours at just shy of the bubble back rate can take up to 1/2hr. (54gal)

I have identical model with the same problem. I tried all the above suggestions without success, returned to dealer who could duplicate the problem but could not fix it, essentially they did not know what to do. I had to slow the fresh water fill to a trickle and it takes a long time (>40 min) to fill fresh 39 gal water tank.

I finally stuffed a rag around the fill hose in the neck of the inlet to seal the inflow. This seemed to create a water-tight seal that results in a siphon effect downstream inside the walls of the airstream. Once the siphon effect kicks-in (it takes about 10 seconds of forcing the rag from being spit back out while maintaining a seal), the remainder of the filling occurs normally without have to hold the rag in place.

My impression is the inlet filler hose inside the walls is at or near the same height as the inlet valve on the freshwater tank (probably a poor design by choice). There is no place for trapped air to escape and hence the immediate back flow of water. Hope this helps

Thank you so much for detailed explanation.
