Did you use tap or bottled water with your baby?

I have a 14 month old, and we live in an area with well water. Even though we have a water softener and a system to get rid of the extra iron, I don't even like to drink the water (but I know I'm picky... my husband and friends will drink it). I'll use it for cooking, but when my son was on formula, and now even when watering his juice down 14 months later I still use bottled water (not spring, always either baby water or distilled). Is there a point when I should just start using our tap water, or should I stick with bottled for a while longer. If so, how long? Whether you have well or city water, did you use the tap or bottled for you baby?
