How many people have never drank water from the tank?

I keep our tank water (as well as fresh water hoses and tote) well sanitized because our toddler likes to drink the water coming out of the shower wand. I also figure, even if you don't drink a big glass of it, you are inhaling it while showering and it is getting on the dishes you are washing. I drink a bit from time to time but prefer bottled water for drinking because I can keep it cold in the fridge, and a case of Arrowhead is only 4 bucks at Costco.
