My water heater just exploded!

Makes me nervous..never understand why any builder would put a water heater in the attic as mine is..

Actually it's in my attached garage/workshop/Ham shack/reloading room/man cave. But they put it in the corner butt up against the wall and that's where the damage is. Even though the supply pipe to the the tank is closed, water is still coming in from somewhere. I can't even see where the water is coming from. I had to shut off the water to the whole house.

On the bright side it's a good test of my water preps.
