Thanks for your comments. I will probably get the well water tested this year. My next cabin project is to install the drain, vent and water supply piping. Plumbing is new territory for me, so things may move slowly! I'm planning on only using the well water for washing and the bathroom. There is a spring in the next town where locals get their drinking water! I'm planning to do the same thing. The flashing around the stove pipe is some kind of high temperature silicone material that was recommended by the metal roofing supplier. I have to replace the inside black pipe before the fall. I discovered it is easier to use piping from the same manufacturer because the pipe is the correct diameter. I'll check out your videos.
