The pipe running to my kitchen sink froze overnight, probably because it runs in front of a basement window under the floor and the temperature outside last night was -19ºF! That’s -28ºC! OMGWTFBBQ!
The hair drier is now pointed at the pipe in the basement, clamped to the rafters with quick clamps, in an attempt to melt the pipe. My brother is on the way with a kerosene heater to put in the basement to speed up the process.
UPDATE: As I was writing this, the water started flowing again. YAY!
