On my same trip to Florida trying to outrun the bad weather, noticed that we had no water or toilet flush. Had to double back to North Chicago to Liberty factory where Bill, the service manager, worked us right in to investigate. After removing , he soaked the pump in ? to dissolve any sediment that was rendering the the pump " frozen". I use city water ( even though we live on a horse farm in the suburbs)and have not experienced this problem with my old Travel Supreme with its' smallish water pump. Do I need to " exercise the pump " every week while in it's heated storage barn or did I have just bad luck? It's a 5 year old coach.By the way , everyone at Liberty were extremely helpful!! My pump problem was discovered on Sunday in Missouri, yet in minutes I had Gary Patterson and Troy on the phone suggesting roadside cures . When all failed they arranged for me to come in the next day and dropped everything to get me taken care of right away.A CLASS COMPANY!
