Just limited to the garage. Thanks for asking. House is on a slab with a step-down to the garage. I had a lot of kits stored in banker's boxes stacked on the floor. That's that stuff that got soaked. Have some kits where the original boxes and decals are ruined, but the plastic is OK. Still sorting through it.
Of course when we discovered the leak, the shutoff valve for the water heater also leaked, so had to shut off the main to the house for a day.
The water heater was about eight years old, which I'm told is about the average life these days. I've been in the habit of flushing it out once a year, but as they say, stuff happens.
