Check that the tank vent isn't plugged.. When filling tank - insure water comes out the overflow - and not just back up the fill pipe.

Thanks I will check the overflow to see if that's the problem, problem right now is the motor home is in storage and covered up, but next month have to take it out for our first trip to Fl.so I would like to get this resolved so we will have water while driving.
