I just bought a side by side refrigerator and I have hooked everything up correctly, I used the pre-existing line that was ran for just a ice maker on the old fridge which made a lot of ice with no problem, our current one has ice and water, the water works with moderate pressure, but no water is running up to the ice maker, I've already disconnected my hoses from everywhere, checking for clogs or kinks, I've determined that it is the water pressure without a doubt, is there any attachments to get to increase my pressure for just the line to the fridge?
