Water in heating vent
So my 2nd story bathroom was flooded, resulting in water pouring down into my heating vents. I turned down the furnace for now until I knew what effects the water might have, but can't find any info about it on-line. My gut instinct says that it's fine, or they would have some kind of codes on how vents have to be installed in places where water is around (bathrooms, kitchens, laundry rooms, etc.). My gut instinct, however, isn't always right. Can anyone help me out with this? Thanks!
