10 month old bldg with floor drains that smell
Have poured down water, as instructed, to get rid of bad odors coming from floor drains. Water alone isn't doing the trick so I'm now pouring bleach. That does the trick for about 4 of 5 work weeks. Should I contact contractor? Could they've done something wrong w/plumbing? any other suggestions on how to get rid of bad smells for longer than 4 days?
