The sewer lines carry the untreated waste away from your homes and commercial areas to the treatment plants and disposal centers. However, there are many reasons why sewer lines repair may be needed.

What Causes Sewer Line Collapse?

Multiple issues can cause a sewer line collapse. Some of the major reasons behind sewer line issues are as follows:

  • Your sewer line may face a problem of tree root incursion. Here, the tree roots that grow near the main sewer pipe may damage the sewer pipe walls. These weakened walls will leak out water from the sewer system. Additionally, the added moisture attracts the tree roots that grow near the sewer line. This aspect can lead to weakened joints and wastewater removal issues as well. With time, the pipe can become completely clogged, causing a serious sewer line blockage.
  • Misalignment of the pipes is another major issue. Here, the pipe joints are not properly aligned, which allows the sewer water to seep out the surrounding area. The eroded earth around the pipe can damage the pipe further,
  • Orangeburg pipe is made from compressed tar. Once the targets eroded due to the aging, it can lead to the exposure of the internal sewer system, causing a serious sewer line collapse.

How to Clean Sewer Lines

First, it is important to diagnose the real cause of the trouble. If your sewer line collapses, hire a plumber to diagnose the exact cause of the issue. Determining the exact cause will help to decide the correct way of dealing with the issue. After the issue has been determined, the following options can be considered for the repair:

  • Rooter and drain cleaning will help to restart the flow of the wastewater from your home. This task has to be completed as a priority. Otherwise, the wastewater may start to rise in your home. Also, this fix is only temporary. It will solve the problem in the short term, giving enough time for long-term measures to be taken.
  • Video camera inspection helps to determine the exact location of the fault in the sewer line. The plumber can inspect the issue can check the exact problem in detail. Once the problem is determined, it is easier to take the necessary steps to correct the sewer line issue.

After the cause of the issue has been determined, the following permanent solutions can be used:

  • Hydro jetting focuses on punching a hole through the sewer line. This hole allows the wastewater to flow freely. Similarly, it helps to remove any grease and tree roots as well. This way, the solution provides long-term benefits.
  • Similarly, pipelining is another useful option as well. Here, new seamless plastic pipes are placed within the old pipe. This way, the line is completely replaced without the removal of the previous system. Such pope lining allows the stoppage of any leakage or other related problems from the old pipe.
  • Pipe Bursting helps to hydraulically pull up the previous pipe and replace it with a new pipe. This method offers a long-term solution.

Cost of Sewer Line Replacement

Sewer line replacement costs are subjective and depend on several factors. First, the size of your home and the condition of the sewer line are important determinants. If the sewer line is badly damaged, a complete replacement may be required, which costs higher than casual repairs. Similarly, the type of sewer line repairs is also important. A trenchless sewer line repair has minimal costs compared to a traditional repair. The main reason is that the trenchless repair does not involve any large-scale excavation activity or removal of giant molds from the earth. On the other hand, the traditional repair requires extensive trenching and may also require replacing other related components of the sewer line.

Additionally, the cause of the sewer line damage also determines the cost of its replacement. Clogged pipes can be cleaned at a much lower cost than tree roots removal. Similarly, the deterioration and age of the pipes have to be considered. Very old pipes may require complete replacement, which could drive up the costs to a few thousand dollars. Repairing and replacing such pipes is necessary to avoid any serious damage.
