4 Most Common Causes of Clogged Sewer Lines | Bishop Plumbing

Last updated 7 years ago

Clogged sewer lines are a major problem. They are often expensive to correct and they can cause awful sewer back-ups. The good news is that clogged sewer lines can be prevented. Check out the following common causes of clogged sewer lines to see what you should avoid to prevent a major plumbing problem.


  • Food Items: When pieces of food slip through your sink’s drain, you are increasing your odds of a clogged sewer line. In most cases, it takes more than one piece of food to clog your sewer, but food build-up will eventually cause a problem. If you think too much food slipped through your drain, consider calling a trusted Chicago plumber to check your drain and sewer line.
  • Toilet Paper: Only use as much toilet paper as you need and do not flush too much at one time. Overuse of toilet paper is the most common cause of household clogs.
  • Tree Roots: Tree roots spread wherever they can find water and nutrients. The inside of a sewer line is an ideal location for tree roots because they can always find water and food. Tree roots find cracks or holes in your sewer line, creep in and block your sewer line. It is important to regularly remove tree roots with sewer maintenance provided by your local Chicago area plumber. 
  • Oil and Grease: Avoid rinsing oil, grease and fat down your drain. Oil and grease cling to the sides of a sewer line and can eventually clog your sewer.
