When wastewater flows in the wrong direction, it can lead to a messy and potentially hazardous situation. Sewage backup is a common plumbing issue that can wreak havoc on your home and health. In this blog, we’ll delve into the causes and effects of sewage backup, with a focus on what happens when sewage backs up in a house.
### Causes of Sewage Backup
* **Clogged Drains:** Obstructed drains are a major culprit of sewage backups. Hair, grease, food particles, and other debris can accumulate in pipes, restricting water flow and causing sewage to back up.
* **Tree Roots:** Invasive tree roots can penetrate sewer lines, causing cracking or crushing that leads to sewage leaks and backups.
* **Collapsed or Broken Pipes:** Aging or damaged pipes can develop cracks, holes, or other structural issues, allowing sewage to escape.
* **Grease Buildup:** Fats and oils can solidify in sewer lines, creating blockages that result in sewage backup.
* **Heavy Rainfall:** During periods of extreme rainfall, stormwater can overwhelm sewer systems, causing backups in homes and businesses.
### Effects of Sewage Backup in a House
* **Water Damage:** Sewage backups can flood homes, damaging floors, walls, ceilings, and furniture. Prolonged water damage can lead to mold growth and structural instability.
* **Health Hazards:** Sewage contains harmful bacteria, viruses, and parasites that can pose health risks to occupants. Exposure to sewage can cause skin rashes, gastrointestinal issues, and respiratory problems.
* **Property Value Loss:** Sewage backups can significantly reduce the value of a property, as buyers are often reluctant to purchase homes with a history of plumbing problems.
* **Insurance Issues:** Homeowners insurance policies may not cover sewage cleanup or repairs, leaving homeowners responsible for costly expenses.
* **Odor and Mess:** Sewage backups produce foul odors and create a messy environment that can be extremely unpleasant for occupants.
