Causes of Sewage Backup and How to Prevent Them

Sewage is a form of black water — highly polluted floodwater that comes from sources such as the public sewer or the road. Consequently, homeowners who have a sewage backup in their houses need to fix the flooding fast or risk endangering their health and their own property. To help prevent sewage backups in their homes, here is some valuable information all homeowners need to understand. 

Sewage Backup Causes

  • Clogs — Sewage may back up into a home when the home’s drain pipes or main sewer line become obstructed. For instance, if one toilet creates a sewage backup, the drain connected to this bathroom will likely be clogged. However, if all bathrooms or bathtubs at the house create backflows, then there may be a clog from the primary sewer line. Clogs can consist of hair, grease, or other solid substances that wind up in the drains.
  • Tree Roots — Trees can grow long roots which intertwine with the sewer line. Roots can grow into a pipe and cause holes or crush the sewer line by growing around it. Even if the origins in the lawn aren’t the problem, roots from nearby trees may reach the sewer line and damage it.
  • Damaged Sewer Lines — In the past, pipes were made from cast iron and clay Valves that didn’t last long. Aging sewage systems may break down and crack, causing sewage backups and flooded basements. Plastic sewer lines have now become the standard.
  • Heavy Rainfall — A great deal of rain can overburden the city’s sewer lines. If the public sewer can not handle surplus rain, the water may make its way into sewer lines that are connected. This puts the house in danger of water backflows.

How to Prevent Sewage Backups

  • Not pouring grease down the drain — Cooking oil can harden within pipes; it slowly prevents debris away from draining, creating a clog. To dispose of fat or grease, it ought to be poured into a heat-resistant container and then chucked in the trash after it melts.
  • Disposing of newspaper goods correctly — Flushing hygiene products such as paper towels, diapers, or womanly products down the toilet might quickly clog a sewer line. Thus, all paper products must be lost safely in the trash.
  • Installing a brand new plastic pipe or cutting tree roots — To prevent tree roots from damaging the sewer lateral (the line buried in the yard), it should be replaced with a brand new plastic pipe. If tree roots still grow in the sewer lateral, the roots must be trimmed sometimes.
  • Installing a backwater prevention valve –— This fixture allows the sewer to depart but prevents it from backing up into the house. Backwater valves are typically installed into a sewer line and at times to a drain line at the cellar.
