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.
For sure, I was sweating as soon as I realized the water wasn’t flowing. I’ve had pipes burst in winter before and I am not eager to repeat the experience. Fortunately for me I caught it and started applying heat quickly enough. it thawed out really quickly, so I’m guessing there wasn’t much ice in there, just enough to plug the pipe. Definitely felt like a close call.
