What Causes Sewage Backup?

There are four main causes for sewer blockages and sewage water damage:

• Solid Flushes. The most common cause for sewage backup in Vallejo, CA is a blockage in the pipe between the home or building and the city main. This is usually caused by solid objects that accidentally entered the system such as disposable diapers, garbage, toys, or other debris.
• Structural Defects. Different structural defects can develop over time and eventually cause major damage to the system, leading to a serious overflow that will require sewage removal in Vallejo, CA and a complete reconstruction of sewer lines. These defects include misaligned pipes, pipe collapses, and cracks or holes in the line.
• Root Infiltration. Tree roots are a major cause of sewage backups. They can enter the service pipe at joints and spread, causing blockages along the way. Growing tree roots can also create structural defects by cracking the pipes as they expand.
• City sewer backup or surge. If the backup occurs in a city sewage line, the wastewater will normally overflow out of the lowest possible opening. In some homes or buildings, especially those with basements, the overflowing sewage wastewater may exit through the home or building’s lower drains and toilets.
