Ah, to own an old house

The dishrack was broken, and needed a screw to be fixed.

I went downstairs to get a screw.

I heard running water... uhoh.

The humidifier was running water all over the floor, and had been all night.

I had to move the washer to get to the humidifier.

I had to remove the temporary subfloor to get to the water

I had to clean the vacuum cleaner to sop up the water

When I poured the water into the sink downstairs, it backed up.

So... my humidifer has a new motor, I have new permanent sub-floor, my laundry machine and dryer are in better positions (I think) and my downstairs sink is cleaned out and scrubbed out.

And the dishrack is fixed.
