LOL, we use nothing that doesn't go through our softener & reverse osmosis first. After seeing & meeting the morons that run our water department, I ran tests on the tap water available. PH off the scale & harder than a witches' tit. Really? Be advised, if you value your health, you'll look into things and take no one's word for the "quality" of your drinking water. And the Illinois EPA isn't to be relied upon as a quality inspector. Asked for a plant inspection, and they had the vendor that's responsible do an inspection on themselves. Wow, wish I could grade my own paper. Bottom line, it's your health, and the health of your family.
