Here's the apparent culprit.This is a disconnected vent we should have taken out, but what's the problem as long as it doesn't leak, right?
So while we're watching, I mean supervising, the repairs we notice the strap that attaches the power line to the weatherhead. This is not good with another storm with high winds approaching.
So the local utility (PG&E) is contacted and they will be out "Sometime today". I disconnect any expensive electronics I can think of that might be ruined by a catastrophic failure, and then wait....and wait. They didn't say by 5 or by midnight. So I rig up a tensioning ratchet rope to prevent total failure, and then reconnect everything I had disconnected. I turn on the computer and the tech shows up. So now it's about 2 pm. It's starting to get dark again. The tech doesn't have the part, and besides I've rigged up a nice system! They'll get to it next week.
I pack up and leave trying to think of anything I've forgotten and also thinking about whether I trust the setup I left. Two miles down the road I realize I've left my good shoes back at the house and I don't feel good about what I left.
I turn around, it starts to rain. Halfway back there are two lightening strikes in the ocean. Should I get up on the roof? I'm really not happy with the set up. It's raining harder. I get home, grab the ladder, get up on the roof and fix the set up and get down ASAP.
