Your home's sewer line works quietly underground, carrying wastewater away from your property every single day. When problems develop in this critical system, they can quickly escalate from minor inconveniences to major emergencies that threaten your home and wallet. Understanding the most common sewer line problems and how they're fixed can help you spot warning signs early and take action before small issues become costly disasters.

What Causes Sewer Line Damage?
Sewer lines face numerous threats both inside and outside your pipes. Tree roots naturally seek out moisture and nutrients, making your sewer line an attractive target. As roots penetrate through tiny cracks or joints, they expand and cause significant blockages and structural damage. The clay pipes common in older Fort Worth homes are especially vulnerable to root intrusion.
Ground shifting and settling can also wreak havoc on underground pipes. North Texas soil conditions, particularly our expansive clay soil, can cause pipes to shift, crack, or even collapse as the ground moves with seasonal moisture changes. Temperature fluctuations and age-related deterioration further compromise pipe integrity over time.
Inside your pipes, what goes down your drains matters tremendously. Grease, oil, and fat solidify as they cool, gradually coating pipe walls and narrowing the passage. So-called "flushable" wipes, paper towels, and feminine hygiene products don't break down like toilet paper and can create stubborn blockages.
The Most Common Sewer Line Problems
Tree Root Infiltration
Tree roots represent one of the most destructive forces your sewer line can face. Roots can grow into pipes through the smallest openings, then expand to completely fill the pipe diameter. Once inside, they trap debris and create blockages while continuing to grow and damage the pipe structure.
Signs of root infiltration include:
- Slow drains throughout your home
- Gurgling sounds from toilets or drains
- Frequent backups despite clearing visible clogs
- Unexplained patches of extra-green grass in your yard
- Sinkholes or indentations near your sewer line path
Professional plumbers address root problems using specialized equipment. A sewer camera inspection first confirms root presence and location. Hydro-jetting uses high-pressure water to cut through roots and clear the line. For severe cases, pipe bursting or traditional excavation may be necessary to replace damaged sections. Some situations call for root barriers or pipe lining to prevent future intrusions.
Bellied or Sagging Pipes
A bellied sewer line occurs when a section of pipe sinks lower than the surrounding areas, creating a valley or negative slope. These low spots collect water and waste instead of allowing it to flow freely toward the main sewer connection. Over time, sediment accumulates in these bellies, leading to recurring clogs.
This problem typically results from improper installation, soil erosion, or ground settling beneath the pipe. You might notice persistent slow drains, frequent clogs in the same area, or standing water in your yard above the affected pipe section.
Fixing a bellied pipe usually requires excavation to access the affected section. The plumber will remove and replace the sagging portion, ensuring proper slope for drainage. In some cases, the surrounding soil needs stabilization to prevent future settling.
Pipe Corrosion and Deterioration
Older sewer pipes, particularly those made from cast iron or clay, naturally deteriorate over time. Cast iron pipes can rust from the inside out due to hydrogen sulfide gas produced by waste breakdown. Clay pipes become brittle and crack with age. Even some older PVC pipes can degrade when exposed to certain chemicals.
Corroded pipes often show warning signs before complete failure:
- Discolored water in toilets or drains
- Foul odors inside or outside your home
- Repeated clogs despite professional cleaning
- Visible rust stains on fixtures
- Unexplained increases in your water bill
Depending on the extent of corrosion, solutions range from spot repairs to full line replacement. Trenchless pipe lining can rehabilitate moderately corroded pipes by inserting an epoxy-coated liner that hardens to create a new pipe within the old one. Severely deteriorated sewer lines may require complete replacement using either traditional excavation or trenchless pipe bursting methods.
Grease and Debris Buildup
Even if you're careful about what goes down your drains, grease and debris can accumulate over time. Cooking oils, soap residue, hair, and food particles combine to create sticky deposits that cling to pipe walls. These buildups gradually narrow your pipe's interior diameter, restricting flow and eventually causing complete blockages.
Kitchen drains are particularly prone to grease accumulation. When hot grease goes down the drain, it travels some distance before cooling and solidifying. Bathroom drains collect soap scum, hair, and personal care products that form dense clogs.
Professional hydro-jetting effectively removes these stubborn buildups. This process uses water pressurized up to 4,000 PSI to scour pipe walls clean, restoring full diameter and flow. Unlike chemical drain cleaners that only bore a small hole through clogs, hydro-jetting completely removes buildup and leaves pipes significantly cleaner.
Broken or Cracked Pipes
Pipes crack and break for various reasons—ground movement, heavy traffic or construction above the line, freezing temperatures, or simply age. Even small cracks allow soil and roots to enter the pipe, leading to blockages and further damage. Large breaks can cause sewage to leak into the surrounding soil, creating health hazards and potentially contaminating groundwater.
Watch for these signs of broken pipes:
- Sewage odors in your home or yard
- Soggy patches in your lawn with no clear water source
- Foundation cracks or settling
- Pest infestations attracted to leaking sewage
- Multiple slow drains or backups
Modern repair methods depend on the break's location and severity. Spot repairs can address isolated breaks without excavating your entire yard. Trenchless technologies allow plumbers to repair or replace pipes with minimal digging—often just two small access points. Traditional excavation remains necessary for extensive damage or when local conditions prevent trenchless methods.
How Professional Plumbers Diagnose Sewer Line Issues
Proper diagnosis is crucial before any repair work begins. Professional plumbers start with a detailed sewer camera inspection, threading a waterproof camera through your cleanout or drain to visually examine the entire line. This footage reveals the exact nature, location, and extent of any problems.
The camera inspection provides concrete evidence to guide repair decisions. You'll see exactly what's wrong rather than relying on guesswork. This transparency helps you make informed choices about repairs and often saves money by targeting only the damaged sections rather than replacing entire lines unnecessarily.
Additional diagnostic tools might include hydrostatic testing to check for leaks, smoke testing to find hidden connection points, and electronic line locating to map your sewer system precisely. These technologies allow for accurate, minimally invasive solutions tailored to your specific situation.
Protecting Your Home with Preventive Maintenance
Regular sewer line maintenance can prevent many problems before they start. Schedule professional inspections every few years, especially if you have older pipes or large trees near your sewer line. Annual hydro-jetting removes buildup before it becomes problematic, and routine camera inspections catch small issues before they require major repairs.
Simple daily habits also protect your sewer line. Never pour grease down drains—instead, let it cool and dispose of it in the trash. Use drain strainers to catch hair and food particles. Only flush toilet paper and human waste. Consider your landscaping choices carefully, planting trees away from sewer lines or choosing species with less aggressive root systems.
