Water is condensing a whole lot on the well tank, water softener tank, and cold water pipes near the well tank. There is some rust on the lower weld on the well tank. I am resisting running a de-humidifier because of the energy use. I have a small window open in the basement as well. There is no or not much odor down there. Most of the water usage is in the evening, and since it is from a deep well, is nice and cool. I could put some anti-sweat insulation on the tanks and the pipe I guess, or just run the de-hudifier. Any ideas? I'd like to save energy. Thanks.
