Excellent Idea..........So I opened the new filter case assy and the white (input) and blue (to water dispenser) have the push to release connection inside. The Grey (line to icemaker) has a metal circular crimp, like a pex ring, with a clear plastic cover securing it to the water solenoid valve. I pushed in on this and the line will not release, so it looks like I will still have to find the connection point up in the icemaker area. I thought about using a compression splice on the rear outside of the refrigerator, but don't really like using them on plastic pipe. Am I missing something on how to remove the grey line from the water valve?
