It is hard to imagine anything more disgusting than being exposed to raw sewage, but there is something worse than the smell and the sheer disgust to be concerned about. Sewage can carry all types of diseases, such as E-Coli, Hepatitis A, Typhoid fever, Gastroenteritis, and Dysentery among many others.
The reason for bringing this up is that there are different events that could cause sewage to back up into your home, bringing all these diseases with it. If you have a blocked main sewage line, your toilets could start spewing out sewage, or issues with your septic system could have the same effect. This is why it is important to keep an eye on the way water flows down your sinks. One serious sign that something might be brewing is when you notice gurgling sounds, bubbles, or disturbed water in your toilet when there is a heavy rainstorm outside. Those are signs that you should take very seriously.
