Bathroom sink stayed liquid overnight with just dripping, but the kitchen sink is on an exterior wall and froze solid last night. I got under there with a heat gun and got the water flowing again, fortunately the whole system didn’t freeze so nothing burst. I also installed a heating cable with a thermostat on the pipe, got it wrapped up snug under some foam insulation, hopefully that’ll keep it liquid as long as I keep some water running through it. gonna monitor tonight and see how it goes.
Sorry for no pics, it is very cold and I went as fast as possible.
Yes, but that’s not what they said. On an outer wall, yes. But not on the outside of that wall.
Correct, it’s just inside the exterior wall under the house, but the crawl space under the house is quite well ventilated so a brisk wind can bring it down to the same temperature as outside. My floors are currently very uncomfortable to walk on with bare feet.
