Spoke too soon.

Well, the tank wasn't full when we got home from work today, it was empty again. But I found what is likely the reason: I had left a faucet running, more than a drip, but not wide open, in the old house. What little had managed to accumulate in the tank was used by Gab when she took a shower when she got in from work today. Arrrrrggggghhhhhh! Bad enough that it is STILL not good, but worse that it was because of my own mistake. I am so tired of learning from my mistakes. Hopefully it will be better in the morning.
