What can cause a sewer blockage? There are three main causes of a sewer blockage. First one is a clog. Don’t use your toilet as a wastebasket – only human waste and toilet paper should be flushed down your toilet. Do not abuse your garbage disposal, putting the wrong items in it or running a large number of food scraps at one time can become lodged in your sewer line. Never pour grease or fat down a drain, it can harden in the drain and collect debris and create a stubborn clog. The second one is tree roots. Even if you don’t have a tree directly above or near your sewer line, roots from a neighboring yard can make their way into your sewer. Tree roots can work their way into your sewer from a crack and continue to grow and trap debris causing a clog. The third is a broken or collapsed sewer line. Although plastic sewer lines are now the norm, older homes have cast iron and clay pipes that can break down and collapse over time and cause sewer problems. A professional plumber can check out your situation and pinpoint the cause of your home sewer backup. Call De Hart Plumbing to come to the rescue.
