My original plan was to have a hot bath while reading Evil Editor's Why You Don't Get Published, then all warm and rosy, pop into bed. That was before I noticed that the bath was less than lukewarm. Before I heard trickling water under the stairs. Before I pried off the back of the closet and saw water on the floor around the water heater.
Well, the part that can be dealt with at 8:30pm is dealt with. I've turned off the tap at the top, I've clicked over what looks like the right switch in the fusebox, I've wrapped a towel around the bottom of the tank, and I'm having a small glass of port instead of a hot bath, while the Consumer Reports page on water heaters is open in another tab.
Fortunately I have tomorrow off, because I'll be spending it getting a new water heater installed.
