Sewer Cleaning questions, answered by experts

The cost to clean a sewer line is about $370, ranging from about $190 to $550 on average. The specific cleaning method and the problem's severity will impact the project's overall cost. Some of the most common sewer line cleaning methods include:

  • Snaking or rodding: $100–$250

  • Hydrojetting: $350–$600

  • Chemical treatments: $600–$1,000

  • Repair or replacement: $1,000–$7,500

If used correctly and sparingly, root killer shouldn’t damage your pipes. Make sure to follow the instructions on the back of the bottle or the company’s website to avoid any unintended damages. However, when it comes to copper sulfate, it’s better to avoid it. This type of root killer can damage your plumbing and the surrounding environment.

Knowing the signs can alert you to a clogged drain line. Clogs cause slow drainage or cause no drainage (if there’s a complete blockage). You may also notice foul odors, gurgling noises, water backing up in other appliances on the same line, or a poorly flushing toilet. If you experience any of these issues and think your line might be clogged, call a plumber.

If you’re not using a septic system, problems with your home’s plumbing won’t cause this—it’s a city problem. A large blockage in the municipal sewage lines may cause those lines to back up into your home. This is extremely unpleasant and can be a serious health risk due to bacteria and other contaminants. If this occurs, call a pro (or your city) immediately.

It might be possible to dissolve hair caught in a drain, but it’s usually not a good way to go about clearing the clog. Some sources mention that baking soda and vinegar can do the trick, but this won’t actually dissolve the hair. The hydrochloric acid in drain cleaners can dissolve the hair over time, but it will much more quickly destroy your plumbing pipes and leave you with bigger issues. The best way to remove hair is to do it manually with a drain snake or to have a plumber use an auger to pull clogs out.
