Hi all,

So, recently one of our 2nd floor toilets overflowed and some of it leaked into our heating vents. The amount of liquid that seeped into the vents was probably half a cup (before I managed to contain the overflow via towels and clothing). The liquid that did get through, ran down the vent ended up seeping through a crack in the kitchen roof drywall, and the heating vent in the basement.

Once all the liquids stopped flowing, we pretty much ran everything through with Clorox Bleach and/or dishwashing detergent. We also cleaned

Should I be concerned at all with sediments of fecal matter developing into mold in the drywall and heating vent?

-- And just FYI (don't know if this matters): living in Chicago, we will be approaching the winter season, so our homes will be quite dry during that season. Not sure if this will prevent mold from developing.
