Blockage can occur when sewer lines are blocked, which prevents wastewater from flowing through the drainage pipes. Because sewage contains viruses and contaminants that can cause severe illness, it is a potential danger. You must quickly fix a sewage backup in your basement. Knowing the causes of sewer backups in your home or basement can help you avoid a dangerous situation. Here are some tips to help you prevent and deal with sewage backups in pipes.

Causes of a Basement Sewage Backup

  • Sewage backups can occur when your main sewer line or drain pipes become clogged. If a single toilet causes a sewage backup in your home, it is likely that the drain connecting to that toilet is clogged. If all the toilets and bathtubs in your house create backflows, it is possible that the main sewer line has become clogged or that the sump pump has failed. Hair, grease and other solid materials can cause clogs in drains.
  • Tree Roots-Trees may grow very long roots that can become intertwined with your sewer line. Roots can grow in pipes and cause damage to the sewer line. Even if your roots aren’t the problem, roots can grow from nearby trees and cause damage to your sewer line.
  • Damaged Sewerlines – Pipes made from cast iron or clay piping in the past don’t last long. The pipes can crack and break down as they age, which can lead to sewage backups or flooded basements. Nowadays, plastic sewer lines are the norm.
  • Heavy Rainfall – Can heavy rain cause sewer backups? Yes, heavy rains can cause sewer backup in your city. The excess rain can get into the sewers. Your home is at risk from water backflows.

How to prevent a basement sewer backup

  • Do not pour grease down the sink. The hardening of cooking oil in your pipes can cause a blockage and block your drains, causing clogs. After it cools, you can pour the grease or fat into a heat-resistant container.
  • Properly dispose of all paper products. Disposing of feminine products, such as diapers and paper towels, down the toilet, can cause clogs in your sewer lines. You can save yourself the trouble by throwing away paper products.
  • Cut tree roots or install a new pipe. Install a new pipe to replace the sewer lateral, which is the line that runs through your yard. Cut the roots if they are still growing in your sewer liner.
  • Install a backwater prevention device. This fixture allows sewage out, but it prevents it back up in your home. Backwater valves are usually installed in a sewer line or a drain line in your basement.
  • Maintenance of your sewage pump. Make sure your sump pump isn’t sitting on any debris like gravel or silt. This could cause damage to the motor. Place it on a flat, level brick. To prevent debris from entering the sump basin, make sure it has a filter cloth around it.

What to do if you have a basement sewer backup

A professional restoration company will be able to help you with any sewage backups in your basement. Here are some things you can do to minimize the damage done to your home by the restoration crew.

  • Evacuate the affected area. Pets are also at risk from sewage contaminants.
  • The flooded area should be turned off. Potentially, appliances or electrical wires could come into contact with standing water.
  • Be careful if the main circuit breaker’s location is in the basement. You should not be near any electrical devices if you are unable to turn off the power.
  • Before you walk through sewage water, wear protective clothing such as a facemask and eyeglasses.
  • Turn off the main water supply valve to your home.
  • Notify your insurance company of the sewage backup. If you have purchased additional endorsements for drains or sewers, sewer backups will not be covered by your standard homeowners insurance. Learn more about homeowners and water damage.

  • You should not use your water supply system until you have a backup.
