Last night I’m lying comfortably on the couch, playing a game, when Sara comes upstairs from her float. “The pump, it made a weird humming noise and then the circuit breaker blew. I don’t know where the breakers are.”
There are in fact several, both two regular circuit breakers and two ground-fault interrupters. Turns out it was the breaker on the power bar, so I reset it and gingerly tried the pump again. Nothing but a weird humming noise. I turned it right back off.
