Sewer smells can range from a minor nuisance, to an over-whelming, nauseating, and potentially dangerous situation. Most sewer smells occur due to improper installation of a fixture, or cracks in existing plumbing drains or vents. They can be somewhat quick and simple to diagnose and resolve, but some require hours of inspection and testing to accuratly pin-point the cause and source of the smell. The most common sewer smell encountered is caused by a dried out p trap, usually caused by going long periods of time without use of a fixture, most commonly floor drains.
