filter system compatible with copper line
I was planning on installing an RO system under my sink to supply water to the icemaker in my refrigerator. I found out I cannot run the water through the copper line due to its corrosivness after being filtered. My line to my refrigerator is already plumbed through the wall and is copper.
Is there an undersink filter system that I can use that is ok to run the filtered water through the copper line? Or would I be better off to put an inline filter behind the refrigerator or just use the filter that is in the refrigerator?
