Oh, and the hot water heater died. We didn't notice until I filled a pot to make pasta, and the water was cold. Went and checked, and the heater was leaking. AWESOME.
Called Southwest out. They capped off the lines so we have cold water, at least. (yeah, the cut-off valve? it cuts off water to most of the house. thanks, previous owners.) They'll be back in the morning to install a new unit.
