We drink the water from our FW tank which is filled with good water from our well before we leave home. We usually carry a few 1. gallon jugs also filled with our well water, basically because I am in the habit of almost always carrying extra water with me all the time. I usually do a flushing routine of the FW tank once a year, which may include disinfecting it too. I do like to carry a in-line filter in case we have to get water at unfamiliar places.
