Came home Sunday to no water. It looks like the service is frozen somewhere in the ~105 feet between the meter which is in the house and the shut-off valve at the curb. It's all underground about 5 feet or so. The only local plumber that deals with such things estimated $400-1000 to thaw it with an electric welder. He wants to connect in the house and at a fire hydrant down the block. I'm not sure that's a good idea because I think most of the heat will be generated in the city's iron pipe instead of in my copper. I don't think among all my friends put together we could come up with enough welding cable to do this job. I read here https://www.ridgidforum.com/forum/t22013-2/#post202756 about inserting a smaller tube into the line and pumping in water to thaw the ice. Anybody have experience home brewing something like this? The main question is what kind of tubing to use. My other option is to just wait a month or so for it to thaw. That's doable since I'm the only person here most of the time, but it wouldn't be much fun.
