I have looked around online, but haven't seen such a thing.
We recently just a bad leak in our laundry room. Fortunately, we caught it quick and were able to get the water cleaned up pretty fast. Unfortunately, a good bit of water poured into the air vent in the floor. That, of course, then flowed down into the air duct and then leaked from there onto the drywall ceiling in the finished basement.
Which leads me to wonder if any such thing exists that would prevent or minimize a reasonable amount of water from flowing into an air vent on the floor? Only thing I can see are deflectors, but that wouldn't really do the trick.
