Although new to this forum, my wife and I have been practicing the retirement life in our class A for nearly three years now. As we travel about we find more well water than treated city water and the iron and odor is sometimes unbearable (to say nothing of the hard water issues). We use an inline filter plus a four inch built in filter, neither of which do much for the iron and nothing for the hardness. There are plenty of systems claiming to be the cure all for water woes but do they really work? Are they a hassle? Are chemicals readily available? Is there a good reliable all-in-one system? We would like to hear about the good systems, the bad systems, and anything in between.
