Great advice, I had a friend who had a toilet tank crack while away, it is the last thing I do when going away from my house for more than a day.Another PSA:
Shut the water off when you're going to be away for more than a day.
Any plumbing in the whole house can fail under supplied pressure at any time, not just washer or dishwasher or icemaker hoses, even though it probably won't.
