Took the new small Craftsman wet/dry vac out back and used it to pull the water out of the A/C drain pan pipe. When we had issues with the A/C earlier this week I also saw that the drain pan in the attic was almost full. I figured a $60 vacuum was worth a try before calling out a plumber. It pulled a gallon of water through along with some stringy gunk that hopefully was the clog.
Heading out in a little while to get a new lawn mower. Old one has lost a lot of compression. It was a good mower (Toro self-propelled walk behind) but I was a bit neglectful with oil changes.
