It's been bloody windy all day, so a lot of the leaves have left the tree, but hopefully they're away down the road by now. I'm hoping they're not all blocking the gutters. Again.
After work, I got up in the roof and found that the pot I'd left for the furnace was almost full of water, but the thing has been struggling to start. Screw it, I've plugged it all back as it was before I started. I'm thinking that the pressure switch could well have failed, so now I just need to figure out how to test it, and where I'd get a replacement.
