I turn mine off when I am not in the coach for fear of a water line leaking and flooding the coach. I do not see how leaving them on, but not running water, drains the batteries. I prefer to fill my 160 gallon tank when I need water and then I am not worried about overfilling my sewer tank, plus I once flooded my coach when the RV park had 110 lbs. of water pressure. Yep, the water lines broke and flooded the coach.
