Host Mammoth Question.
Is there a valve to switch between usING tank water and city water?
Forum Discussion
Most RVs have a ball valve that can stick and prevent water from coming in through the freshwater hookup. A couple of more items 1. Water Pressure reducers can also stick closed. 2. You can always add water directly into your holding tank if you can get the freshwater intake to work and you don't want to fix (like on a trip).
