outdoor sump
Well it dropped to -7 last night and I was a little worried about my outdoor sump, so I set my alarm for 3:00 am and checked it out: (77.4) YES! So back to bed I went. This morning, when I got up it was 77.8 I have yet to see it fall below 77. It's supposed to go down to -12 this week, so that will be a big test, but I don't anticipate a problem.
