We have a heated water hose, but over the summer and fall the heater wire and insulation had moved far enough away from the water hose to have the water freeze overnight in the water hose.
The last photo shows foam insulation on upper left, bare white water hose in the middle, faucet on the right and heater wire in the lower middle of the photo. The white water hose in the middle should be enclosed with the heater wire and foam insulation around the white water hose.
I will have re-insulate and re-tape the water hose later today. While it snows here in Vancouver, WA, it’s unusual – generally more cold rain than snow.
