When you checked the winterizing valve that cdevill mentioned could you see water in the line feeding the water pump. If there is water at this point (and the valve on the pump is in the correct position) your pump should prime if it is working. If there is no water you may have a kink in the line from the fresh water tank or it may be blocked with construction debris from when the trailer was built. This is not uncommon. Disconnecting this tubing and blowing back should clear it and moving the tube around can sometimes work out the kink. I hope this helps, Hank
