As previously said, we leave ours on when we are at the campsite, but try to remember to turn it off if we plan on being gone for while, just in case. And even when hooked up to city water, we will turn that off too, because... Once, a dughter left a sink fawcet slightly open and when we returned, we saw water dripping from the underbelly. The grey tank filled and overflowed from the shower drain.
