Sewer Line Services

Your sewer line is the main artery of your plumbing system, carrying all wastewater from your home or business to the municipal sewer system. When this critical pipe develops problems, the consequences range from slow drains and foul odors to raw sewage backing up into your property. Coast City Plumbing provides comprehensive sewer line services across Greater Los Angeles, from diagnostic camera inspections to full sewer line replacement. Our licensed plumbers have the equipment and expertise to handle sewer problems of any scale, and we offer 24/7 emergency response for urgent sewer situations.

Signs Your Sewer Line Needs Repair

Sewer line damage often develops gradually, and catching the warning signs early can save you thousands of dollars in emergency repairs. If you notice any of the following, your sewer line may need professional attention.

• Persistent clogs in multiple drains throughout your home, especially if they recur shortly after clearing
• Foul sewage odors coming from drains, your yard, or near the foundation
• Slow drainage in sinks, tubs, showers, or toilets that worsens over time
• Sewage backing up through floor drains, toilets, or bathtub drains
• Unexplained wet or soggy patches in your yard, even during dry weather
• Unusually green or lush patches of grass over the sewer line path
• Foundation cracks, settling floors, or sinkholes forming in the yard
• Gurgling sounds from toilets or drains when water is running elsewhere in the house
• Pest activity such as rats or insects that may be entering through cracks in damaged sewer pipes

If any of these signs are present, do not wait. A small sewer problem can escalate into a full backup or pipe collapse within days. Call Coast City Plumbing for a same-day sewer camera inspection to determine the exact condition of your line.

Sewer Camera Inspection

A sewer camera inspection is the first step in diagnosing any sewer line problem. Our technicians insert a high-resolution waterproof camera into your sewer cleanout and advance it through the entire length of your sewer line. The camera transmits live video to a monitor, allowing us to see the interior condition of your pipe in real time. We can identify root intrusion, cracks, offsets at joints, bellied sections, buildup, and other defects with pinpoint accuracy. The camera also records footage and distance measurements, giving us a precise map of your sewer line and the exact location of any problems. This information is essential for planning the most effective and least invasive repair strategy.

Trenchless Sewer Repair

Traditional sewer repair required digging a trench the full length of the damaged pipe, destroying landscaping, driveways, sidewalks, and sometimes even portions of your home's foundation. Trenchless sewer repair eliminates most of this disruption. Coast City Plumbing offers two primary trenchless methods: pipe lining and pipe bursting. Both require only small access points rather than full excavation, preserving your property and reducing project time from days to hours in many cases.

Benefits of Trenchless Repair

Trenchless technology has transformed sewer repair for Los Angeles homeowners and businesses. The advantages over traditional excavation are significant.

• Minimal property disruption -- No trenches through your lawn, driveway, patio, or landscaping. Your property stays intact.
• Faster completion -- Most trenchless repairs are completed in a single day, compared to several days or weeks for traditional excavation.
• Lower overall cost -- Less labor, less equipment, and no landscape restoration bills. The total cost is often less than conventional methods.
• Durable results -- Modern trenchless materials are rated to last 50 years or more and resist root intrusion, corrosion, and joint separation.
• Preserves property value -- No torn-up yards, broken concrete, or destroyed hardscaping that require expensive restoration.

Pipe Lining (CIPP)

Cured-in-place pipe lining, commonly called CIPP, rehabilitates a damaged sewer line from the inside without removing the old pipe. Our technicians insert a flexible liner saturated with epoxy resin into the existing pipe and inflate it so the liner presses firmly against the interior walls. The resin cures and hardens over several hours, forming a seamless new pipe within the old one. The result is a smooth, jointless interior surface that eliminates root entry points and restores full flow capacity. CIPP is ideal for pipes with cracks, joint separations, minor offsets, or moderate root damage where the original pipe still holds its general shape.

Pipe Bursting

When a sewer line has collapsed, is severely crushed, or has lost too much structural integrity for lining, pipe bursting provides a trenchless replacement option. During pipe bursting, a bursting head is pulled through the old sewer line, fracturing and displacing the existing pipe outward while simultaneously pulling a new HDPE pipe into position behind it. The old pipe is destroyed and replaced in a single pass. This method is particularly effective for replacing deteriorated clay, cast iron, and Orangeburg sewer lines that are beyond repair. Pipe bursting requires only two small access pits at each end of the affected section, leaving the rest of your property undisturbed.

Main Sewer Line Replacement

The main sewer line connects your property to the city's municipal sewer system and carries all the wastewater from every drain in your home or building. When this line fails, it affects your entire plumbing system. Coast City Plumbing performs main sewer line replacement using both trenchless pipe bursting and traditional open-trench excavation, depending on site conditions, pipe depth, and the extent of damage. New main sewer lines are installed using HDPE or PVC, materials engineered to resist root intrusion, chemical corrosion, and ground movement far better than the clay and cast iron pipes found in many older Los Angeles homes. A properly installed main sewer line should serve your property reliably for 50 years or more.

Lateral Sewer Line Replacement

The lateral sewer line is the section of pipe that runs from your home's foundation to the connection point at the main sewer line, typically located under your front yard or driveway. This section is your responsibility as a property owner, not the city's. Lateral lines are vulnerable to root intrusion, soil shifting, and age-related deterioration because they often run through areas with heavy landscaping or vehicle traffic above. Coast City Plumbing replaces lateral sewer lines using the least disruptive method available for your property. We assess pipe depth, soil conditions, and surface features to determine whether trenchless pipe bursting or targeted excavation will deliver the best result for your situation.

Root Intrusion

Tree roots are the number one enemy of sewer lines in Southern California. The warm climate and abundance of mature trees mean roots are constantly seeking the moisture and nutrients present in sewer pipes. Roots enter through joints, cracks, and even through the porous walls of older clay pipes. Once inside, they grow rapidly and form dense root balls that trap debris and eventually block the pipe entirely. If left unchecked, root growth can crack and collapse the pipe itself. Our approach to root intrusion combines mechanical root cutting to restore immediate flow, hydro jetting to clean the pipe walls, and camera inspection to assess the extent of pipe damage. For chronic root problems, we discuss long-term solutions including pipe lining, replacement, or root barrier treatments.

Bellied Sewer Line

A bellied sewer line occurs when a section of pipe sinks or sags due to ground shifting, soil erosion, or improper installation. The sagging section creates a low point where waste and water collect instead of flowing freely toward the main sewer. Over time, this pooling area accumulates sediment, grease, and debris that cause recurring blockages. A bellied pipe cannot be fixed with cleaning alone because the structural problem remains. Repair typically involves excavating the affected section and relaying the pipe at the correct grade. In some cases, if the belly is minor, we may be able to address it with pipe lining techniques.

Sewer Backup Emergency

A sewer backup is one of the most unpleasant and potentially hazardous plumbing emergencies a homeowner can face. Raw sewage backing up through floor drains, toilets, or tub drains poses serious health risks and causes significant property damage. Common causes of sewer backups include tree root blockages, grease buildup, collapsed pipes, and overwhelmed municipal sewer systems during heavy rain. When you experience a sewer backup, call Coast City Plumbing immediately. Our emergency team responds around the clock to contain the situation, clear the blockage, and determine the underlying cause so it does not happen again.

Sewer Line Cleaning and Maintenance

Regular sewer line cleaning is the best preventive measure against backups and major sewer problems. Our professional sewer cleaning service uses high-pressure hydro jetting to remove grease, scale, mineral deposits, and small root intrusions before they develop into full blockages. We recommend sewer cleaning every one to two years for most residential properties, and more frequently for properties with known root problems or older clay or cast iron sewer lines. Proactive sewer maintenance is far less expensive than emergency repair or replacement.

When to Replace Your Sewer Line

• Frequent sewer backups despite repeated cleaning
• Multiple sections of the pipe are cracked, collapsed, or offset
• The pipe is made of Orangeburg, a tar-paper material that deteriorates over time
• Root intrusion has caused extensive structural damage to the pipe walls
• The pipe has significant bellying that cannot be corrected with spot repair
• Your home is over 50 years old and still has the original sewer line
• Camera inspection reveals widespread corrosion or deterioration
• Repair costs are approaching the cost of a full replacement
• You are planning a major renovation and want to address aging infrastructure proactively
