Mainline vs. Secondary Drain: How Do You Know What You're Dealing With?
The key difference is how much wastewater each line carries. Mainline problems affect multiple drains. Secondary drain problems, also called branch lines, are usually limited to one fixture.
Your mainline, or sewer line, is the large central pipe that carries all wastewater from your house to the street sewer. Mainline clogs have several common causes:
- Flushing items that don't break down, like wipes
- Solidified grease and fats
- Mineral buildup from hard water
- Tree roots growing into the pipe
- Aging or damaged pipe
- Improper pipe installation
Any of these can build up and obstruct the flow of wastewater out of your home. If you're seeing symptoms in more than one fixture, call us and we'll find out which line is the problem.
Signs You Need Sewer Line Cleaning in Denver, CO
Sewer line problems tend to show up in several places at once. These are the signs to watch for:
- Sewage or water backing up into a tub, shower, or floor drain
- Multiple fixtures draining slowly at the same time
- Gurgling or bubbling sounds from your pipes
- A toilet that gurgles when you run the washer or another fixture
- Foul sewage odors indoors or in your yard
- Damp, soggy, or unusually green patches in your yard
- It's been a long time since your sewer line was last cleaned
If you notice any of these, don't wait for a full backup. Call us and we'll find the cause.
Benefits of Denver Sewer Cleaning
Regular sewer cleaning costs far less than cleaning up after a backup. Here's what you gain:
- Free-flowing pipes that carry water and waste out of your home as they should
- Fewer clogs and fewer plumbing emergencies
- No more sewage odors indoors or in your yard
- Early warning — we can spot damaged or failing pipe before it becomes a larger repair
- Peace of mind that your home's main line is in good shape
A clean sewer line is one of the simplest ways to protect your home from a messy, expensive backup.
Our Denver Sewer Cleaning Methods
We choose the method that fits your clog and your pipe:
- Cable augers (sewer snakes) — a motorized cable breaks through blockages in the mainline.
- Hydro jetting — high-pressure water clears grease, scale, and roots and cleans the pipe wall, not just the clog.
- Camera inspection — when warranted, we send a camera down the line to find the cause and location of the clog. See sewer inspections.
Cleaning is the right fix for buildup. If the camera shows a cracked, collapsed, or failing pipe, we'll explain your options for sewer repair or sewer replacement.

Our Work in ActionSewer Problems Common in Denver Homes
Denver's weather and housing stock create specific sewer line problems. Here's what we see most often:
- Tree roots — mature trees in older neighborhoods send roots into sewer lines in search of moisture.
- Freeze-thaw cycles — stress aging pipe and joints.
- Hard water scale — mineral buildup gradually narrows pipes.
- Older pipe materials — cast iron, clay, and Orangeburg lines are prone to buildup, cracks, and root intrusion.
- Grease — kitchen grease solidifies in the line and collects debris.
Knowing what's in your line, and what's around it, helps us choose the right cleaning method and how often it should be done.
How to Prevent a Clogged Sewer Line in Denver, CO
The best way to prevent a clogged sewer line is regular maintenance. We recommend scheduling sewer line cleaning every 18 months to 2 years. We'll clear your line and look for any problems that could lead to clogs later.
You can help between visits, too:
- Don't pour grease or oil down your drains
- Don't flush wipes or other items that don't break down
- Keep an eye on trees with roots near your sewer line
Do this, and you'll have far fewer sewer surprises.
Sewer Cleaning Costs in Denver

Denver Sewer Cleaning FAQs
Sewer line cleaning clears the main pipe that carries wastewater from your home to the street sewer. We remove grease, debris, scale, and roots so wastewater flows freely.
Look for more than one fixture draining slowly or backing up at once, gurgling sounds, sewage odors, or sewage backing up into a tub, shower, or floor drain. A problem in a single fixture is more likely a branch line.
Stop using water in the home, including toilets, sinks, and the washing machine, and call us. We offer same-day service and can come out quickly to find and clear the clog.
We recommend every 18 months to 2 years. Homes with older pipe, mature trees nearby, or a history of backups may need it more often.

When warranted, yes. A camera shows us what's causing the clog, where it is, and whether it's debris or a failed pipe.
It depends on the clog. An auger breaks through many blockages. Hydro jetting is better for grease, scale, and roots because it cleans the full pipe wall. We'll recommend the right one after we inspect the line.
