Sewer Repair & Main Line Rooter Service in Los Angeles, CA

When more than one drain in the house backs up at the same time, the problem usually isn't any single fixture — it's the main sewer line that everything else drains into. A blockage or structural failure in that line affects the whole house at once, which is why this kind of backup shows up as a pattern across multiple drains rather than one isolated clog.

24/7 Rooter Service clears main lines with heavy-duty rooter equipment sized for the larger diameter and heavier blockages of a main line versus a branch drain, and every main line job is followed by a camera inspection to confirm the line is actually clear — not just flowing again temporarily.

For structural problems — cracked pipe, root intrusion at a joint, a collapsed or bellied section — clearing alone won't permanently fix it. We diagnose which situation you're in before recommending a repair, so you're not paying to clear the same damaged line every few months.

Signs You Need This Service

• Multiple drains backing up around the same time, especially the lowest fixtures in the house
• Sewage backing up into a tub or shower when you flush a toilet elsewhere
• Gurgling from multiple fixtures when water runs anywhere in the house
• A cleanout that's visibly under pressure or overflowing
• Repeated backups despite the line having been cleared recently
• Sewage odor in the yard, especially near the cleanout or along the line's likely path

Our Process

Residential & Commercial Service

Residential main line service covers single-family sewer laterals. Commercial and multi-unit properties have larger, higher-volume main lines that need bigger equipment and often benefit from a scheduled maintenance interval rather than waiting for the next backup to force an emergency call.

24/7 Rooter Service is licensed, bonded, and insured in California (License #845109). We give upfront pricing before any work begins, stand behind our repairs with a workmanship guarantee, and are available for genuine emergencies around the clock across Los Angeles.

Frequently Asked Questions

How is this different from regular drain cleaning?

Drain cleaning clears an individual fixture's line. Main line service addresses the larger pipe that all of your fixtures ultimately drain into before reaching the city sewer connection — different equipment, and it usually points to a bigger issue than a single clogged sink.

Why do multiple drains back up at once instead of just one?

They're all downstream of the same blockage point in the main line. Water and waste back up to the lowest point they can reach, which is often a floor drain or the lowest fixture in the house.

I don't know where my main line cleanout is — can you find it?

Yes, locating (or installing, if none exists) a functional cleanout is a routine part of main line service, especially on older properties where the original cleanout may be buried or paved over.

Will rooting damage my pipes?

Professional rooting equipment is sized and operated to clear blockages without damaging sound pipe. If a camera shows the pipe itself is already compromised, we'll tell you before recommending repeated rooting as a long-term fix.

How often should a main line be cleared as maintenance?

It depends heavily on the property's tree coverage and pipe age and history — we can recommend a realistic interval based on what we see during the first service call rather than a generic schedule.

Is hydro jetting better than rooting for a main line?

Rooting clears the immediate blockage fast. Jetting clears the full diameter of the pipe rather than just cutting a path through it, which is the better call for a line with a history of repeat backups from grease or scale buildup.
