Sorry about your plumbing, and not having water. When thy hooked up my fridge and the plumbing to it, they pointed out to me, "This is a cut-off switch from the water to my fridge. It sits insid the house just to the right of the fridge. " Not all homes are the same, but it is a piece of mind knowing it is there. You might ask the plumber about installin one when he replaces the leaky line.

My parents back in the day, had their large a/c unit in the attic. Who knew this was a good idea. It also started leaking. That was a nightmare situation.
