Wow... It's really been that long since I've posted an update? Sheesh, I need to take myself out back and shoot me.
I guess the MACNA run-up, execution, and exhaustion that followed did a number on me.
As for the state of the tank, I've not done a whole lot of note since my last update. Filled it, let it run for a while, then drained the system a couple of times to be sure. Determined that the 'leak' was from salt creep that had accumulated down inside the plastic trim, so as it gathered moisture from the air, it dripped through the gaps and looked like a leak. After cleaning out those gaps as best I could (compressed air, etc) the next fill up didn't show the dampness I'd seen previously.
Post MACNA I had filled and drained it again, and attempting to get as much of the gunk off the glass and walls of the sump as I can. Work, holidays, and vacation has been getting in the way of that, but I should be ready to get movement going in the next couple of weeks.
Put a 50% deposit down on a 20KW whole house generator a couple of weeks ago, so hopefully I'll have that installed before hurricane season.
