well maybe its just a dry floor drain, drain traps there job is to keep gases from coming back into the house put a couple buckets of water in each, basement floor drains cause a lot of odor.

if your going to be gone for more than a month or so, put a cup of vegtable oil in each p trap. most any kind will do. it won't evaporate or go rancid so you won't have sewer gas coming in. otherwise, once the water in a p-trap evaporates, you'll get sewer gas in the house.
