How Often Should Sewer Lines Be Cleaned?

As a homeowner, you know that things can and will go wrong in your home.  And sometimes those things couldn’t possibly have been foreseen.  Which is quite often the case when it comes to your sewer lines.

Your sewer lines are hidden; therefore, it’s hard to recognize when and if there’s a problem.  This makes it even more important that you have some knowledge about what signs to look if you want to prevent a potential disaster, and quite possibly, higher repair or replacement costs.

Learning how often to have your sewer lines cleaned, the signs that indicate you may have a problem and what your options are once you do discover a problem, will help you make a more educated decision about what your needs are and how to go about having the repairs completed.

How Often Should You Have Your Sewer Lines Cleaned

As a good preventive measure you should have your sewer lines cleaned every 18-22 months.  If you are experiencing problems more often than that, you may need to call a plumber and schedule a video inspection of your pipes.

Your plumber will insert a video camera down through your pipes to help visually determine what other issues may be causing your sewer back-ups.  That video inspection will then enable him to make the proper recommendation for whichever repair is necessary to correct the problem.

The Warning Signs That Indicate Your Sewer Lines Need Cleaned

There are several things that could cause sewer back-ups and they are not all due to dirty pipes.  Sometimes they are, but not always.

  • Roots:  Tree roots penetrating your pipes are the number one cause associated with sewer back-ups.  The roots grow into the pipes and will continue to grow until they fill the pipes completely.  Or, in many cases, the roots will break the pipes, creating an even bigger problem.  A video inspection will help confirm if you have tree roots growing in your pipes.
  • Bellied Piping:  A bellied pipe is simply a sag in your pipe.  A sag can occur when part of your pipe slopes down, which creates a “belly” effect.  This is usually caused when the soil around your pipe becomes loose and breaks, making the soil around your pipe unstable and allowing it to sink.  Over time, a bellied pipe will allow waste to accumulate at the bellied part of the pipe, which in turn will create a blockage.  A video inspection will tell your plumber all he needs to know and how to proceed with the proper repair.
  • Grease:  Grease is a pipes worst enemy.  Many homeowners casually pour their old, used grease from cooking down the drain.  This is the worst thing you could do.  That grease will eventually turn solid which creates a blockage in your pipes.  If this happens, you will need to have your pipes hydro-jetted.

The Warning Signs To Look For Are:

  • You see raw sewage backing up into your drain, toilet or bathtub
  • Gurgling sounds coming from the pipes
  • You see water around the floor drain in the basement
  • If water backs up into the shower or bathtub when using the washing machine
  • Reoccurring clogs or multiple clogged drains
  • Slow drains
  • Sewer odors

Options For Having Your Sewer Lines Cleaned

  1. Have the problem diagnosed by a trained professional master plumber through the use of a video inspection to ensure you are getting the proper diagnosis for the problem.
  2. If tree roots are the issue, using a mechanical auger may take care of the problem.  A sewer auger has a rotating spiral head with teeth that will cut through the tree roots removing the obstruction.  However, this will only take care of the existing problem because the roots will grow back.  Therefore, you’ll need to have a chemical tree root removal performed or you may have to dig up the invasive roots.  If you’re looking at this option, please read our previous blog post on how to remove tree roots from pipes. There are times when the pipes are too badly damaged by the roots and will have to be replaced.  A video inspection will help determine what needs to be done to fix the problem.
  3. A hydro-jetting of your pipes may be required depending on the reason for the blockage.  A hydro-jetter pumps up to 4,000 psi of water through your pipes to clean them out and remove the blockage.  After hydro-jetting, if the hydro-jetting was done due to roots in your pipes, you can have your plumber flush your pipes with a chemical to kill any remaining roots, if the root invasion wasn’t too severe to begin with.

The Take Away

Keeping your sewer pipes clean is just as important as any other preventive maintenance task you perform on your home.  Therefore, you should schedule a cleaning every 18-22 months if you want to avoid the hassle of a sewer back-up or allowing a problem to go undetected to the point it becomes a major repair.

  6. My wife and I have recently purchased our first home. We don’t have any experience maintaining a home, and we’re looking for advice. I didn’t realize grease can solidify in pipes causing blockages, and a sewer cleaning service should be called if this should occur. I’ll be sure I remember this information moving forward.

Mom usually does that, and I do too because we both thought that it’s alright to do that. Now I’m getting really worried. Maybe it’s for the best that we get professionals to get the drains cleaned just to be sure. Thanks for sharing!

    I think my sewer is clogged up. Having it cleaned would be a good idea. Someone with experience should do this for me.

    Thanks for helping me understand that cleaning should be done since it can help detect possible issues which can be addressed immediately and keep you from the need to have it repaired in the future. I will definitely do that, so I should probably find a plumber tomorrow. I hope we are not too late since we have been in this house since 2017, and we have never gotten it cleaned due to not knowing the importance of it.
