Sewage backup occurs when wastewater from your plumbing system flows back into your home or business. This can be a devastating event, causing damage to your property and posing health risks to your family. ### Causes of Sewage Backup There are a number of factors that can contribute to a sewage backup, including: - **Blockage in the Sewer Line:** Tree roots, grease, and other debris can accumulate in your sewer line, causing a blockage that prevents wastewater from flowing out. - **Collapsed Sewer Line:** The sewer line can collapse due to old age, corrosion, or ground movement, which can also lead to a backup. - **Clogged Drain:** A clogged drain in your sink, toilet, or bathtub can prevent wastewater from draining properly, causing it to back up into your home. - **Overwhelmed Sewer System:** During heavy rainfall, the sewer system can become overwhelmed with excess water, causing backups in homes and businesses. ### Effects of Sewage Backup Sewage backup can have a number of negative consequences, including: - **Property Damage:** Sewage backup can cause extensive damage to your home or business, including flooring, walls, furniture, and appliances. - **Health Risks:** Sewage contains harmful bacteria and viruses that can cause illness, including gastrointestinal problems, skin infections, and respiratory problems. - **Unpleasant Odors:** Sewage backup can release foul odors that can be difficult to eliminate. - **Loss of Use:** Sewage backup can make your home or business uninhabitable until the problem is resolved. ### Why is Sewer Backing Up in House?
