This is a great topic. I also have well water. The manufacturers (spelling??) don't take this in to consideration. Recomendations usually say tap water and NOT distilled water. So what are we supposed to do??
Since we live in a Chicago suburb where many people around us have Lake Michigan water my DH will fill up water from work or else where.
Also have been frustrated with the cost of Rowenta's but eventually they leak... is it the well water or the Rowenta design??
I am trying to use spray bottle but it just isn't the same.
I am frustrated too.
