This home is a older home with gable roof. Half the roof had the gutter come into the basement and just shoot water all over into a floor drain that was filled with dirt (I cleaned it when I inspected). Water damage all over and the owner says “I never go down there so I never paid attention”. I was just a little caught of guard by the design. I don’t know if they use to rain harvest but if they did that set up is long gone.
