Sewer Cleaning
When more than one drain in the house backs up at the same time, the problem usually isn’t one fixture, it’s the main sewer line that everything else drains into.

What Is Sewer Cleaning, and How Is It Different From Drain Cleaning?
Sewer cleaning clears buildup, grease, roots, and debris, from the main sewer line that carries wastewater from your entire home to the municipal connection, as opposed to drain cleaning, which addresses an individual fixture’s branch line. The clearest sign you’re dealing with the main line rather than a single drain is that multiple fixtures act up at once: toilets gurgle when you run the washing machine, or a tub backs up when the dishwasher drains. That pattern means everything is sharing one blocked path rather than each fixture having its own separate issue. Sewer cleaning is typically done through an access point called a cleanout, and depending on what’s causing the blockage, a plumber may use a motorized cable or hydro jetting for a more thorough result.
One slow drain is local. Every drain acting up at once means the whole system’s backed up.
Signs You Need Main Sewer Line Cleaning
The key difference from a single clogged drain is that these symptoms show up across multiple fixtures.
- Multiple drains backing up or draining slowly at the same time
- Toilets gurgling when you run the washing machine or another fixture
- Slow draining throughout the house rather than at just one sink or tub
- A sewage smell in the yard or near the cleanout
- Recurring backups that individual drain cleaning hasn’t resolved
What You Can Check Before Calling a Plumber
Main line cleaning typically requires professional equipment and cleanout access, but noting the pattern helps with diagnosis.
- Note whether the issue affects just one fixture or multiple at the same time, that distinction matters
- Locate your sewer cleanout if you know where it is, usually a capped pipe near the foundation or in the yard
- Avoid running large amounts of water or laundry if multiple drains are already backing up
- Don’t pour chemical drain cleaner down a main line backup, it typically won’t reach far enough to help and can be a safety hazard if a plumber needs to open the cleanout afterward
Why Compare Quotes Instead of Calling Just One Plumber
Here’s what actually matters when the whole system’s backed up:
- Matched with up to three licensed, insured plumbers experienced in main sewer line service
- Compare pricing before agreeing to cleaning versus a more involved repair
- Free to use, with zero obligation to hire anyone you're matched with
A backed-up sewer line affects the whole house at once, which makes it one of the more disruptive plumbing problems to live with, but also one with a fairly clear fix once it’s properly cleaned. Comparing quotes gets it resolved without paying for more than a standard cleaning if that’s all it needs.

Frequently Asked Questions About Sewer Cleaning
How much does sewer line cleaning cost?
Most main sewer cleaning runs $150 to $500 depending on the length of the line and the method used.
How do I know if it's my main sewer line and not just one drain?
The clearest sign is multiple fixtures acting up together, like a toilet gurgling when the washing machine drains, since that means they share one blocked path.
How often should a main sewer line be cleaned?
For most homes, every one to two years is reasonable, more often if you have mature trees near the line or a history of root intrusion.
Can tree roots be cleared with sewer cleaning?
Yes, cabling or hydro jetting can clear root intrusion, though a camera inspection helps confirm whether repair is also needed afterward.
Is sewer cleaning the same as a sewer camera inspection?
No, cleaning clears buildup and blockages, while a camera inspection is a diagnostic tool to see the condition of the pipe. They’re often done together.
Is it free to compare sewer cleaning quotes?
Yes, there’s no cost to compare quotes through 3PlumbingQuotes and no obligation to hire anyone.
