In the mechanical room of a new construction house there is some moisture at the bottom pressure treated plated. When I remove the vapor barrier and the insulation and check up against the concrete wall there isn't any moisture on the wall itself or behind the wall. It is only below the pressure treated plate and in front of it on this one wall. I don't understand why this is and could really use some help with this. One other concern i have is on one of the other interior walls that has the finished basement on the other side there is a little bit of moisture in one random spot as well which i don't understand.Right above this is the gas line for the furnace and when i touched the plug on the bottom side which is threaded on or whatever it is it felt a little wet but it isn't leaking not sure why there would be moisture on that. Any help would be greatly appreciated, I want to make sure to take care of these moisture issues and don't want it to lead to something long term. Thanks, Joe
