Thanks guys.
I managed to get the power on last night. I unplugged all the drowned stuff I could and brought my air hose up to blow out the one socket I could not. My phone is toast, constant reboot. Just as well I allow android and whatsapp to back up to my gdrive. I've taken back a spare phone I gave to Mrs S and am in process of setting it up. I hauled the gazebo off the pool and dismantled it this afternoon (only got to bed at 07:30). I've checked around the house, the worst of it was downstairs in the utility room (which was getting a new floor anyway) and the eaves of my office. I've managed to haul out a sleeping bag but I carry all of my stuff for my apartment, when working away, under there. Including the TV and microwave. I'll get to dragging that our later.
It is just a matter of emptying, drying and cleaning now. I found the gutter above my office blocked with moss off the roof and a chunk of mirror (no idea where that came from).
Apparently we're in for round 2 this evening and into tomorrow morning thunderstorms and very heavy rain. Around 12 hours of rain. I'm hoping I have the worst of the issues fixed now. The problem is how to deal with it. I need to pump a chunk of water out of the pool before it hits so that it has some room to fill.
This was the first courtyard
This is in the utility behind there.
