How Important is Distilled Water to Safe Enema?

[sbm]

If you want to do a deep water enema that fills the colon with two or more liters of water, how important is it to use distilled water? The references I found online were very ambiguous on this issue. If I use a system that attaches to a shower fixture, that is obviously going to use tap water. In my area the tap water quality is pretty good (i.e., not much chlorine or heavy metals). I have noticed that after an enema that cleans out my colon that I feel unwell starting about two hours later for about four to six hours.
