Top 5 Signs You Need a Sewer Line Inspection in LA Homes in 2025
Los Angeles has various residential neighborhoods, from Hollywood Hills mansions to cozy bungalows in East LA. Despite the variety, one constant remains: aging sewer lines can cause significant problems if left unchecked. Whether you’re dealing with unexpected drain clogs, suspicious odors, or the threat of invasive tree roots, a professional sewer inspection is the best way to diagnose underlying issues. This guide explores the top five signs indicating it’s time to schedule a sewer line inspection for your LA home.

Why Sewer Inspections Matter in Los Angeles
Aging or Damaged Infrastructure
Many homes in classic LA neighborhoods like Echo Park or Silver Lake were built decades ago, relying on original clay or cast iron sewer lines. Over time, these materials can deteriorate, crack, or become misaligned.
Seismic Activity and Soil Shifts
Earthquakes are a reality in Southern California. Even minor tremors can shift soil and stress underground pipes, leading to minor fractures that worsen over time.
High Population Density
In a city as crowded as Los Angeles, sewer systems experience heavy usage. Multi-unit buildings, condo complexes, and older homes may have outdated lines struggling to handle modern demands.
Top 5 Signs You Need a Sewer Line Inspection
1. Persistent Slow Drains
Water slowly leaves sinks, tubs, or showers across multiple fixtures, suggesting a deeper blockage rather than a localized clog. Common causes include grease, debris, or invasive roots. Consider scheduling a professional drain cleaning or sewer inspection before risking DIY fixes that may worsen the blockage.
2. Gurgling Toilets and Foul Odors
If your toilets gurgle after flushing or your drains emit unpleasant smells, these are classic signs of trapped air and partial blockages in your sewer line. Foul odors can also indicate sewer gas backups, posing health risks. An in-depth video camera line inspection helps pinpoint the blockage’s location.
3. Frequent Drain Clogs or Overflows
Experiencing constant backups in your toilets or lower-level drains is a red flag. Repeated clogs often mean a significant obstruction or root intrusion within the line. If you find yourself plunging multiple drains more than once a month, it’s time for a professional evaluation.
4. Water Backups in Lower Levels
Homes with basements or ground-floor bathrooms often see sewage backups first. This can appear as standing water near floor drains or sewage rising into lower-level toilets or tubs. Swift action is crucial to prevent contamination and extensive water damage. Inspecting and, if necessary, repairing your sewer line can resolve these backups.
5. Visible Indentations or Lush Spots in Your Yard
Unexplained sinkholes, depressions, or unusually green patches in your yard may indicate underground leaks. Sewer lines that leak water can create soft spots or encourage rapid plant growth. Early detection and a professional inspection can prevent major collapses and costly excavation.

How Professional Sewer Line Inspection Works
Video Camera Inspection
Licensed plumbers use specialized cameras to travel through your sewer line, transmitting real-time footage to identify cracks, root intrusion, debris, or structural damage. This minimally invasive approach saves on guesswork and unnecessary digging.
Additional Diagnostic Methods
In some instances, smoke or hydrostatic pressure tests may be used for complex issues. These methods help plumbers confirm the presence of leaks or illegal hookups in high-risk areas.
Why DIY Inspection Isn’t Enough
Homeowners risk misdiagnosing problems, missing hidden issues, or causing further damage without professional tools and training. An expert plumber can interpret camera footage accurately and recommend targeted solutions.

Repair and Prevention Strategies
Hydro-jetting and Drain Cleaning
If camera footage shows grease, roots, or debris, a high-pressure hydro-jetting session can effectively clear blockages. Routine drain cleaning prevents future buildup.
Pipe Replacement or Relining
Partial or complete sewer line repair or replacement is often necessary for severe damage, such as collapsed segments or widespread corrosion. Trenchless relining methods minimize disruption to landscaping.
Trenchless Options
From pipe bursting to cured-in-place-pipe (CIPP), trenchless solutions reduce the need for extensive excavation, saving time and money in dense LA neighborhoods.
