Normally, delivery people won't hook up fridges to the water line for exactly that reason. Did they include hookup as part of the delivery service or was that something extra you asked the delivery men to do for you? It will be interesting to see how they handle this.

No mention that it wasn't included. He even offered to replace the copper line with a plastic line. The leak was at the ferrule/nut area...not a kink in the line.
The store even asked what kind of water line I had....so I assume it's normal for them.
Will post a followup later this morning.

A big question hasn't been answered yet: why was it leaking. Was it a defective line, defective inlet connector on the fridge, or sloppy installation work? It will make a difference in who is responsible for the damages.

It goes without saying that anytime a water line is connected or reconnected to pretty much anything, it should be monitored for a while to check for leaks. A cursory check when it is first hooked up isn't enough. Water pressure can vary through the day due to demand or pressure tank cycling.

You have to make sure the connection has been monitored for leaks long enough to catch the peak pressure period, especially if the house isn't fitted with a pressure reducing valve (PRV).

It was sloppy install work. He cut the old ferrule off and replaced. It was leaking at the ferrule.
I know they should be monitored. In my experience with icemaker leaks....it's a small puddle. Drip...wait a minute...drip. Or at least that's how good I get them on my first attempt. This was drip...wait a second...drip. This was a huge mess...soaking several 2x4 ceiling tiles, wetting about 16 square feet of wood floor,etc.

In looking at my delivery paperwork....I may be screwed. It reads that deliveries are curbside only...and anything else they're not liable for. Will see what happens.

Ouch. A cautionary tale for us all. Best of luck with it.

An update...
THEIR insurance adjuster just left.
We're not gonna be worried about the kitchen floor...no tile problems...he'll not for possible future problems.
Basement laminite seems to have dried fine.

Paying me to pay someone to replace ceiling tiles in theater (bonus...since I did the install myself...I have extra tiles)
Repair/refinish wood floors upstairs. Paying for about half of what I already need to have redone anyway.

So....could've been much worse.
