well the problem with using tap water is that you might be putting back into your body the things you are trying to clean out. Purified water,not filtered, is going to have minerals and things that keep your body functioning properly and it would have never had in it the things tap water does. You are taking a risk that this cleanse may not be as helpful as it could be by not using pure water... you have to make a choice. There is nothing wrong with putting it off, but atleast while you are doing it you wont have to buy any food so many it would even out to the same expenses as if you were not doing the cleanse. I hope i wasnt confusing.. good luck in whatever you decide
