Thank you very much for the information
Seems the consensus is that I am being a little fussy, which is typical of me. I will get the water tested ASAP and until then I will brew a couple batches and hope for the best. I am fairly certain we have hard water (I see the deposits on glasses and plates from the dishwasher) but I don't know for sure. It certainly doesn't have any off taste or smell. In fact it tastes pretty darn good.
