Water supply tube elimination in the refrigerator icemaker
There is no such device. However, when my step-son got married and had no ice maker in his refrigerator he asked us what he could do. I told him that we all used ice trays. when I was growing up. I was shocked when he asked us, "What's an ice tray?". I only mention this because I am not sure of your age. I am certainly not trying to be funny or offend.
