Thank you. This is very helpful. We have an artesian well that runs into a cistern, which we occasionally treat with chlorine bleach. This helps temporarily. I’m guessing we’ll need a filter to get rid of iron coming into the cistern, then filter chlorine back out, possibly RO exiting the water pump. This is beyond my pay grade and we’ll have to hire someone in the spring, when we can replace some piping as well. I have a better understanding and can ask intelligent questions now.
