The bad news: We discovered a water leak behind the refrigerator in the last couple days.
The worse news: We pulled the fridge out, and it’s not leaking from there.
The even-worse news. It’s leaking from the copper supply line inside the wall.
The even-worse news than that. The supply line runs down the wall to the fridge, through the attic, from up another wall from the cold-water supply below the kitchen sink. So I get to go up into the attic to cut and pull copper and new attached PVC line through two walls. In south Florida. In August.

Huzzah! It’s not inside the wall. We just saw the water leaking from the back of the fridge when the icemaker valve opened. I just changed the inlet valves a couple months ago; the joint must have come loose. It just went from a major PITA to a minor repair.
[Update a while later]
OK, as noted in comments, I disconnected the leaking tube from the icemaker line, cut it off square, and reinserted. No joy. It appears to be leaking from the side of the fitting itself, which is integral to the valve, which costs fifty bucks (and I just replaced it less than three months ago). Sigh…
