Over the years, I have bought refrigerators with a built-in automatic ice maker and ice water options. I have noticed these components tend to go south and need repair after a few years. I was wondering if this is due to us having well water. Our water is treated with softener salt if that makes any difference. But, I cannot help but think our water causes a build-up in the lines that makes these components break down over time. And if so, do you have any suggestions on how to clean the lines?
