Plumber question

Wish I knew enough about it to help, but can only add that would be my best guess.

Looking at something along those lines for our house, as I've been bringing home gallons of distilled water for a few years now and would like to stop doing it and stop filling up the landfills with plastic.

We need a water source that's free of the lime and minerals that our rural water system contains, and on the vet's recommendation, started buying filtered water for the cat. Later discovered that using it made our Keurig coffeemaker live longer, as well, so figured it might also be better for the two old people living here.

I worked in a Laboratory and setup a millipore system that produced type 1 grade laboratory water (The cleanest water possible) for laboratory wet chemical testing.  I was testing the air for Sulfur Dioxide and needed the purest water I could get for the laboratory.  I had a prefilter then an R/0 filter with backflushing, Then two Ion exchange filters, then an activated carbon filter followed by a 50-micron bacteria filter. Then I had a 50-gallon plastic barrel that I had on a custom-built metal stand. I then could filter the city water though the millipore filter system and store the pure water the plastic barrel.  I used an electric water pump to pump water out of the barrel for laboratory use through flexible plastic tubing.  There was a conductivity meter on the waterline after the bacterial filter.  This meter told me if the system was working as designed. I had to buy extra filters and replace the filters on a regular schedule or the water system would fail to produce the type 1 reagent grade lab water that I required.  I also had a laboratory-grade HACH conductivity meter that I could use to test the water for conductivity.  Conductivity is the ability of the water to pass an electric current through the water. Pure water will not pass current. Water with lots of Sodium Chloride (Table Salt) will conduct a current.  I could weight out a certain amount of salt on a calibrated analytical scale and then made up reagents to test the system. I also purchased a ready-made solution from Fisher Scientific Company and use them to calibrate the HACH conductivity meter. Now I don't expect people who don't work in a research laboratory to go to all this trouble. But many well to do people can purchase this very system from Millipore Corp. 

The main thing that I would tell you about your system is to make sure that you have replacement filters on hand and replace your filters on a regular schedule. Filters can become contaminated with bacteria and will wear out after so many months/years depending on the filter type. 

I do have a Culligan system installed with a filter for carbon and another for sediment along with a UV light filter to kill bacteria in the water. Hoping someone knows which line on the RO I hookup to for my ice maker.

Yes, The blue line is the filtered water. Tap into that to get water that has been run though all the filters.  

No problem duster!!!
Thanks for letting me copy off your answer sheet so I could get it right!!!
