Scott R Wilmington , IL February 14, 2015 Appliance: General Electric Refrigerator GSS20IEMDWW Ge Refrigerator Gss20iemdww: Leaking waterline. How to replace Refrigerator Cold Water Reservoir Tank. Followed one of many repair videos online. The fitting that hold the waterline ends need pliers to clamp and pull the line out so its a bit awkward. It doesn't take a strong effort it just needs a slight push in. I guess they keep the line secure and water from leaking. Replacing the waterline was simpler. The waterlines push into these fittings and are held snugly. The big problem was the line got kinked after I put it in. You have to put the line in the same spot as the old one. It's a tight fit. Once it kinks it stays kinked. I had to cut a few inches off fortunately there was still enough and I got the end in and it didn't kink. That's it! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
