It's 01:30. Do you know where your maintenance techs are?

Last Sunday night, I put in a maintenance request about the previously dismissed "humidity problem" in my bathroom having developed into an unarguable leak. It took them a few days to find the source of the water; turns out it's the corroded pipe that supplies the water-based HVAC system. They've since worked their way from the leak, on the third floor, down to my apartment on the ground floor, and are now moving out sideways, in search of structurally sound piping. This evening, they determined that they were going to have to enlarge the hole in my bathroom ceiling, because none of the vertical run of pipe was sturdy enough to attach new pipe to. So they did. I showed them out a few minutes ago.

And now I go fall over, because the plumber is supposed to be back bright and early.

[ETA, 13:30: It turns out that it's not just my stack that was without HVAC. Some idiot back at the time of the original installation didn't put in valves, so to work on any of the pipes, the entire building has to be drained. A valve has been installed to cut off the stack containing my apartment, so now everyone but my stack has their heating & cooling restored.]
