Here’s a photo of a category 3 water loss. This is probably the least offensive photo we can show, but it is a sewer back up. Category 3 is when water intrusion results from a grossly unsanitary source, or carries pathogenic agents. Examples of Category 3 water sources include discharge from toilets that originate from beyond the trap, sewer or septic system, and intrusions from the surface of ground water into the structure like flood water.
