We often go in campgrounds where there is no water hookup so for us it is natural to open the pump switch when we get installed. About a month ago we went to a campground that had a water hookup but we mistakenly put the pump switch at on and there was no water in the tank. A/C was on so we could not here the pump. We realized our mistake after 4 hours. Amazingly enough the water pump still works fine.
