Digging: at the damaged section.

Sewer Line Repair & Replacement in Whittier, CA
Several drains backing up at once, water rising in the tub when a toilet flushes, or a clog that keeps coming back? Those signs point to your sewer line, and every flush or load of laundry can push wastewater back up through your lowest drain. Call to get connected with a local plumbing contractor for sewer line inspection, repair or replacement.

Inspection first
A camera inspection shows where the problem is and whether your line needs clearing, a repair or a replacement.
Is it the sewer line?
Signs you may need sewer line repair
A single slow sink usually means a clog in that fixture's drain. When you see trouble in several places at once, or it keeps coming back, suspect the main sewer line that every drain in your house shares.
-
Several drains slow at once
Your sinks, tubs, showers and toilets all drain slowly at the same time.
-
Water coming up a lower drain
Water rises in your tub, shower or floor drain when someone flushes a toilet or the washer drains.
-
Gurgling toilets and drains
A toilet or drain gurgles when other fixtures in your house run.
-
A sewage smell
You smell sewage inside the house or out in the yard.
-
Clogs that keep coming back
Your line backs up again soon after a clearing.
-
Only one drain affected?
One slow sink, tub or toilet more often points to a clog in that fixture's line than to a sewer problem.

Sewage backing up right now?
Stop running water and flushing, keep children and pets away from the area, and call. Raw sewage is a sanitation hazard, and every flush adds to it.
Why the whole house is affected
Why one sewer line can affect every drain
Your sinks, tubs, toilets and washer all drain into one main sewer line that carries wastewater out to the street. When that line blocks or breaks, water from every fixture has nowhere to go, so you see the problem throughout the house.
Not every backup means a broken pipe. If the pipe is still sound, clearing the blockage may be all your line needs. Main-line and drain cleaning
What can go wrong inside a sewer line
- Tree roots getting into the pipe
- Cracked, broken or collapsed pipe
- Older pipe wearing out
- Sagging sections that hold waste
- Separated or shifted joints
- Grease or wipes blocking a sound pipe
Inspection first
Sewer camera inspection comes before the repair decision
You can't judge a buried pipe from the surface. A camera inspection finds where the problem is and what's causing it, and that shows whether your line needs clearing, a repair or a replacement.

Camera inspection
A plumber runs a small camera through your sewer line to find the problem and where it is.
-
2
Diagnosis
The footage separates a blockage that cleaning may clear from damage in one spot or wear along much of the line.

Repair or replacement decision
With the footage in hand, you can compare the options: clearing, a repair or a new line, and which method fits the damage.

Sewer line repair or replacement: the main approaches
Which approach fits depends on what the inspection finds. For you, the practical difference is how much digging each one involves.
Repair · trenchless
Pipe lining
A resin-saturated liner goes inside your existing pipe and cures to form a new pipe within the old one, when the old pipe's shape allows it.
Digging: usually limited to access points.
Replacement · trenchless
Pipe bursting
A bursting head pulls a new pipe through the old one and breaks the old pipe apart around it: a way to replace a full run of sewer line.
Digging: usually an access pit at each end.
In the drawings: dashed = existing pipe · solid = new pipe or liner · broken tan = old pipe being burst. More on trenchless sewer repair
What decides the approach
- The extent and location of the damage
- The pipe's material, shape and condition, and whether it can be lined or burst
- Depth, access, and what sits above the line: driveways, landscaping, trees
Repair or full replacement?
No method is right for every line. Trenchless options can mean less digging, but a badly collapsed or misaligned pipe may still need excavation. Talk through what the inspection found and what each option means for your yard.

Think it's the sewer line? You don't need a diagnosis first. Every backup you wait out adds to the cleanup, so call while the damage is still limited.
Call (562) 273-9788How do I know if it's the sewer line or just a clogged drain?
One slow fixture usually means a clog in that fixture's drain. Several drains slowing or backing up together, water coming up a tub or floor drain when you flush a toilet, gurgling, sewage odors or clogs that keep returning can point to your sewer line. A camera inspection shows what's actually happening. Drain cleaning in Whittier
Do I need a camera inspection before a sewer repair?
It's the most direct way to see what's wrong inside your line and where, and that decides whether you need clearing, a repair or a replacement, and which method fits.
Should I repair or replace my sewer line?
It depends on what the inspection finds. You can often repair damage in one spot. A line with cracks, root damage or sags along much of its length may call for a full replacement instead. Ask about both, and how much digging each would involve.
Can a sewer line be repaired or replaced without digging up the yard?
Sometimes. Trenchless methods such as pipe lining and pipe bursting usually involve less digging, but they depend on your old pipe's condition, shape and access. Some damage still calls for excavating the affected section. The inspection shows which options are realistic for you. Trenchless sewer repair
Is sewer cleaning the same as sewer repair?
No. Cleaning clears a blockage from the sewer line when the pipe is still sound. Repair or replacement fixes a pipe that's cracked, collapsed, root-damaged or separated. If you need cleaning again and again, the pipe itself may be the problem. Main-line and drain cleaning
