How important is water Treatment??

[Danny]

Long time lurker here and a brewer with about 10 partial / all grain (BIAB) brews under my belt.

To date, I've used water straight from the tap (Lower Hutt) without any treatments at all. The last few all grains I have done have been full boils thanks to the addition of a 50l pot to my equipment.

I am missing a major step by not doing anything to the water??

Are there some general rules that I could follow if I needed to something (as opposed to nothing). I have read a few things but end up awfully confused, chemistry was ever a strong subject of mine.

use rain water. i don't get very technical on it, but i hate the taste of town water.
