Main line clogged: the emergency signs
A blocked main shows up as sewage in the lowest fixture, gurgling toilets when the washer drains, or a floor drain that bubbles. Those signs are different from a single stubborn sink. They mean the whole house's wastewater has nowhere to go.
This page is for the main line. For individual fixtures, see drain cleaning. For repairs to damaged pipe, see sewer line repair.
Find the cleanout
We locate the access, outside or inside, and prepare the area.
Clear the blockage
A powered cable with the right head breaks through the clog.
Clean the pipe
We scour the line further, or jet it if the buildup is on the wall.
Verify flow
We run water and, where useful, a camera to confirm a clear line.
Cables, jetting and the camera
A powered drum cable carries blades that cut roots and break up solid clogs. It is the right tool for a blocked main. After the cable opens the line, we assess whether the pipe is clean or merely open. If grease or scale remains, hydro jetting completes the job.
If the clog returns or the cable stops at the same distance, a camera shows whether a break or offset is the cause. We would rather show you than keep cleaning a line that needs repair.
| Common main-line causes | Clue | Likely action |
|---|---|---|
| Roots | Cable returns with fibers | Cut and clean, then monitor or repair |
| Grease buildup | Greasy debris on the cable | Jet the line |
| Foreign object | Cable stops at one spot | Retrieve or camera to locate |
| Collapsed section | Cable cannot pass | Camera and repair quote |
Keep your main line healthy
- Only toilet paper and human waste go down the toilet. Wipes labeled flushable do not break down.
- Keep grease, coffee grounds and food scraps out of the kitchen sink.
- Know where your cleanout cap is and keep it accessible.
- Have a camera check if the line has clogged more than once in a year.
Cost factors
Severity of blockage
A partial blockage is quicker than a solid one.
Access
An outdoor cleanout simplifies the work.
Line length
A longer run takes more cable and time.
Cleaning method
Cable, jetting or both change the scope.
Follow-up inspection
A camera pass is quoted as an option.

Main line backed up?
Call the 24/7 line. A plumber can usually reach you the same day.
Main lines around Tucker
Tucker is in DeKalb County, and the county utility keeps the sewer mains. Whether your clog lives in your lateral or in the county's main decides who pays for the fix. We camera-verify before deciding, and we document anything on the public side. The same service reaches Gwinnett addresses in Lilburn and Norcross.
Preventing a repeat
After a main line is cleared, the question is why it clogged. If the camera shows roots, plan to cut them on a schedule or repair the entry point. If it shows grease, change the kitchen habits and consider a jetting visit. If it shows a defect, schedule the repair.
A line that is cleaned and then ignored will clog again. A line that is cleaned, inspected and then maintained can go years without trouble. Ask for the footage so you can see which kind of line you have.
Homes on wooded lots, such as those in Smoke Rise, can have mature trees near the pipes, which is one reason a camera look helps when a drain keeps returning.
Standards and sources
Plumbing work in Georgia follows the state minimum plumbing code, which is built on the International Plumbing Code (IPC) with Georgia amendments. Ask the City of Tucker permit team which edition and which local rules apply to your address. Plumbers are licensed through the Secretary of State's Division of Master and Journeyman Plumbers, and you can ask for a license number.

Questions we hear from homeowners
Yes. We answer around the clock, and sewage backups are prioritized for same-day service when available.
Multiple fixtures slow or backing up together, with the lowest drain worst, points to the main.
Most are done within an hour or two once we reach the cleanout.
No. Cleaning removes obstructions. A damaged pipe needs repair, which a camera helps confirm.
Roots, grease, scale or a pipe defect are the usual reasons. A camera inspection finds the cause.
