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.
Thanks! I’m quite pleased with it, mostly relieved that all the faucets are flowing and nothing under the house is leaking lol. I’m not sure how narrow an escape it was in actuality but it felt a bit like defusing a bomb.
