I was shipped a new Whirlpool refrigerator today. I had an existing 1/4 " copper tube that I used as a water supply line.
I cut the copper tube with a pipe cutter, and I slipped a compression nut and sleeve on the line. I slid the tube into the water inlet valve and tightened the compression nut.
After turning on the water (and verifying no leakage) I ran a gallon of water out the front dispenser. Suddenly, the fitting to which I attached the compression nut popped out of the valve and sprayed water all over. Apparently, there is nothing to hold this fitting in there. Am I doing something wrong, or is the valve defective?
The compression nut does not leak at all, and the water flows smoothly out of the fitting when it's removed as in the second picture.
This is the view inside the valve where the fitting plugs in. You can see the screen in there that stops debris. I don't see anything covering it.
Update: As you can see in the second picture, there is a lip that something in the green valve is supposed to grab. I can see two metal teeth inside the green valve that probably retract to grab the lip. Unfortunately, I don't see any way of making them retract. The blue cover on the front is like a public restroom screw: it's slotted such that it can be screwed on but not off.
