I walked down to the county road. It's clear. Outside temperature right now is high forties and the sun is shining. The forest service road, which is in shadow all day, has been driven on by people out four wheeling, and all the snow has been packed down into about a half inch of ice. My road, leading up from the county road to the house, is untouched. The snow hasn't melted at all. If it doesn't freeze tonight, and the air is warm it can melt rapidly though. Maybe by tomorrow I can get back up to the house with the Jeep.
I turned off the pump for four hours, then went up and turned on the kitchen sink in the apartment. It took a good while for the water to stop running, which means if I have a broken pipe it can't be much of one. The apartment and shop are probably a good 50 feet higher, or more, than the pump. If there was a break, the water would have run out of the apartment and the pipe would have been empty above the break. That's my logic, anyway. Once I can get in and out to town I will see about getting the stethoscope, unless my wife brings one home with her today.
