It was -22°F (the REAL temp) here Saturday morning. Apparently that is the cold end of the Leaf's "operating temperature" based on the battery temperature gauge but DW got to work. Probably couldn't have driven it if she hadn't had it plugged in and prewarmed the cabin and batteries.
Then yesterday, water pressure dropped while DW was taking her morning shower. I turned off the switch to the controller then back on and pressed the override switch as well. No good. Reset the breaker (it wasn't tripped) and the pump ran. But apparently that was the last time because later in the day, pressure drop again. Nothing I could think of to do got it going again.
Called the well company and left a message. The office guy called this morning, asked if it was frozen. Nope. The repair guy came about 9:30 this morning. Looked at it, took the cover off the pressure switch to look at it, lit his propane torch and a few seconds on the 1/4" pipe under it going to the water pipe, presto it started running.
Turns out there is a TINY hole in that pipe under the switch and when it gets really cold the hole can get frost frozen. Pump won't run if air can't get in/out of that hole. The basement is heated to 45°F but apparently not enough of that heat gets over to the east (rubblestone) wall. The pressure switch is maybe 6" from the wall. So when he asked if it was frozen, I didn't understand what he meant, the PIPE wasn't frozen and we could get low pressure water out of the tank while it pressure, but we stopped using water when the pressure gauge went down below 30 psi and the pump didn't run.
So now I know what to do if it happens again but I think I'll just put a fan down there to move warm air toward the west wall if it gets super cold again.
