I replace the water inlet valve in my refrigerator about 8 months ago. About a week ago, the old plastic water line broke. I forgot how the water line connector worked and broke the valve trying to pull it out. I got a new valve and replacement water line, and it went in easily, just like the video said.
Morals of the story:
1. Know how to remove the old plastic water line. I could have saved myself the price of a new valve if I'd remembered how the connector worked. Unless you have a really old valve design (which my refrigerator came with) you press and hold the plastic ring around the water line as you pull it out.
2. If you're replacing the valve, replace the water line at the same time. If the valve failed, the water line doesn't have much time left.
3. AppliancePartsPros' website did not list the water line for my refrigerator. The water line part number is WR17X1948.
4. Pliers are not listed as required to do this job. They might not be, but in my case I needed them to open the hose compression clamp at the water inlet to the ice maker.
