I'm sure I'm just rewording what someone has already said but it's not like this is a coffee pot breaking or your computer not turning on. A catastrophic failure from a tank like this could ruin an entire home. For instance, I live on the second floor of an appt. building. If this blows me and the guy below me are screwed and I spend the next two years in a legal battle, as if losing my tank wasn't enough. I feel like denying a potential issue is like pouring water on a grease fire.
