About a month ago I noticed water dripping on the basement floor from under the first floor bathroom. I thought it was the old 1980s toilet’s fault and went ahead and replaced it. I noticed the water dripping again and called a professional to reset the toilet. He confirmed there’s no water coming from the toilet: the flange area is dry. We went downstairs and he told me the dripping was coming from condensation on a pipe. Effectively, a segment of one of the pipes that supplies the tub has an enormous amount of water as droplets forming on the outside of the pipe. Does anyone know how to solve it? A dehumidifier is at work but it’s not nearly enough.
