Solid Flushes
The most common cause of sewage backup is a blockage of the lateral service pipe between the home and the city main. This is usually caused by solid objects, accidentally flushed down a household drain.
Structural Defects
Different structural defects can develop overtime and eventually cause a major damage to the system, leading to a serious overflow that will require a complete reconstruction of sewer lines.
Root infiltration
Tree roots are a major cause of backups. Tree roots can enter the service pipe at joints and travel a long way, causing blockages along the way.
