Sawzall: good.

You can't really do serious damage to your house without a Sawzall. But I've got one of those. Actually, the news is goodish. For the last couple of years, in the dead of winter, we've had occasions when there has been a leak down the dining room wall, but a very light one, and it has always gone away once it has warmed up. Once we thought it might be from an ice jam, and good luck ever tracking down a roof leak. But eventually it dawned on us that it was connected with draining the bathtub. Never leaks during a shower, but would occasionally leak in the very cold weather when there was some hydraulic head in the tub. (And, please, if you've never had hydraulic head in your tub, you just have no idea.) But it always went away when it warmed up, so we figured, a little pipe shrinkage, a couple of drips, and I'm not going to rip out a wall and a ceiling for a couple of drips. Lately, many more drips. Not just drips. Spillage. So, today, the Sawzall. Stay tuned.
