On topic, I've never seen so much salt on the roads as I did tonight in the city.
Off topic, the attic pipes that froze are over my laundry room. It's been a problem since I put on the addition over 20 years ago. Putting water pipes in a wall between the house and garage is against code, so we were forced by the inspector to run them up a narrow wall for a closet, into the attic about 6" from the eaves of the steeply pitched roof. Makes complete sense since the pipes go into an attic on the north side of the house that doesn't get sunlight from December to March, and where it's 15 degrees now, while my well insulated south facing garage is a balmy 43.
I built a coffin around the pipes in the attic by insulating the rafters with foam board and topping with R-stupid high insulation, and even cut a vent into the ceiling of my laundry room into the coffin so heat from that room would heat the coffin. Still, the cold line froze.
So my solution is that I have a kerosene heater in the laundry room now to hopefully really get some hot air in the coffin with the pipes. This is either going to work, or the paint is coming off the walls. Not sure why it's sideways.
