A functioning sewer line is essential to maintaining a safe and healthy home environment. However, sewer line issues can develop over time, especially in older homes or properties with mature trees. Left unchecked, these problems can lead to significant damage, costly repairs, and unpleasant disruptions. Identifying the signs of a sewer line issue early on can save you from these headaches, making it easier to resolve small problems before they turn into major ones.
In this guide, we’ll cover some of the most common signs that your sewer line may be in trouble. If you’re noticing any of these issues, it may be time to reach out to a professional. Chisholm Plumbing Heating & Air Conditioning has the expertise to diagnose and address sewer line problems in Mauldin homes, helping to keep your plumbing system running smoothly.

Frequent Drain Clogs and Backups
One of the earliest signs of a potential sewer line issue is frequent clogs or backups in your drains. While occasional clogs are normal, repeated clogs in multiple drains—especially when using sinks, toilets, or showers in different parts of the house—often indicate a deeper issue within the sewer line. Common culprits behind these clogs include tree roots, pipe damage, or accumulated debris that partially or completely blocks the flow in the main sewer line.
Why Frequent Clogs Signal a Sewer Problem
- Consistent Blockages: If you clear a clog in one drain, but it quickly returns or spreads to other drains, there’s likely an obstruction or damage in the sewer line itself.
- Backups in Low-Level Drains: When a sewer line is blocked, wastewater may back up into the lowest drains in the home, such as basement drains or first-floor sinks.
Addressing frequent drain clogs early can prevent more serious problems like sewage backups and water damage. If you’re experiencing repeated clogs, consider a professional inspection of your sewer line to determine the root cause.

Unpleasant Odors in and Around the Home
If you’re noticing persistent sewer-like odors in or around your home, this could be a strong indicator of a problem with your sewer line. Healthy, functioning sewer lines are designed to contain unpleasant gases and odors, so when they escape, it often means there’s a crack, leak, or blockage somewhere in the system. Ignoring these smells can lead to worsening issues and potential health risks, so it’s important to address them promptly.
Why Sewer Odors Indicate a Problem
- Cracks or Leaks in the Sewer Line: A crack or break in the sewer line can allow gases to escape into your home or yard. This can happen due to shifting soil, tree root intrusion, or natural wear over time.
- Blocked Vents: In some cases, sewer line gases may back up into the home due to a blockage in the plumbing vent, which can push odors into living spaces.
- Potential Health Hazard: Sewer gases contain methane, which can be hazardous to your health in large amounts. Addressing sewer line leaks not only removes the odor but also keeps your home safer.
If you detect persistent sewer odors, it’s best to get an inspection to identify the source and determine the necessary repairs. Chisholm Plumbing Heating & Air Conditioning offers sewer line inspections and repair services to quickly and safely address these issues in Mauldin homes.
Slow Drainage Throughout the House
Slow drainage in multiple areas of your home can be another warning sign of sewer line problems. When your main sewer line is partially blocked or damaged, wastewater may struggle to flow freely, causing slow drainage across sinks, showers, and toilets. This issue is especially concerning if multiple drains are affected simultaneously, as it often indicates a blockage in the main sewer line rather than individual clogs in each fixture.
How to Recognize Slow Drainage as a Sewer Issue
- Multiple Slow Drains: If more than one drain in your home is experiencing slow water flow, especially in areas like bathrooms and kitchens, it’s often a sign of a larger sewer line problem.
- Widespread Gurgling Noises: Slow drainage can also create air bubbles, which cause gurgling sounds in drains when water flows slowly. This is a result of trapped air being pushed through the pipes due to a blockage in the main sewer line.
Slow drainage in several areas of the home can be frustrating, but it’s a problem that can be resolved. Our team at Chisholm Plumbing Heating & Air Conditioning can perform a sewer line inspection to identify and remove blockages, ensuring smooth drainage throughout your home.

Lush, Green Patches in the Yard
If you notice unusually lush, green patches or soggy areas in your yard, it could be a sign of a sewer line leak. When a sewer line is damaged or cracked, wastewater may seep into the soil, providing extra moisture and nutrients that cause grass and plants to thrive in specific areas. While a greener yard might seem harmless, it’s often an early indicator of a serious sewer line issue that requires immediate attention.
Why Green Patches Could Signal a Sewer Line Problem
- Leaking Wastewater: When sewage leaks from a broken pipe, it enriches the soil with water and nutrients, leading to rapid plant growth. This often results in unusually green, lush grass or plants above the damaged line.
- Soggy or Sunken Ground: In addition to green patches, you may also notice that certain parts of your yard are persistently wet, even when it hasn’t rained. The ground may feel spongy or sunken, indicating that water is saturating the soil from below.
- Root Intrusion: Tree roots are naturally drawn to sewer lines due to the moisture and nutrients they contain. Over time, roots can penetrate the sewer line, causing further blockages, leaks, and damage to the pipes.
If you see unusual growth patterns or persistent wet spots in your yard, it’s time to investigate further. Contact Chisholm Plumbing Heating & Air Conditioning for a professional sewer line inspection and repair, ensuring the problem doesn’t worsen over time.
Gurgling Noises from Drains and Toilets
Hearing gurgling or bubbling sounds coming from your drains or toilets can be unsettling—and it’s often a sign of a sewer line issue. When there’s a blockage or damage in your sewer line, it can trap air in the pipes, causing bubbles that create gurgling sounds as water tries to pass through. This trapped air indicates that water and waste aren’t flowing properly through the main line, which can lead to more serious problems if left unaddressed.
Why Gurgling Noises Signal a Sewer Line Problem
- Air Trapped in Pipes: A blockage in the sewer line prevents air from escaping, so it bubbles up through your drains, creating gurgling sounds, especially when water is running in other parts of the home.
- Backflow Risk: Gurgling sounds can also indicate that wastewater is struggling to flow down the line. If the problem isn’t resolved, it could eventually lead to backflow, causing sewage to back up into your home.
- Multiple Fixtures Affected: Gurgling sounds in more than one fixture, such as a toilet and a sink, point to a main sewer line problem rather than a clog in a single drain.
If you’re hearing these noises, it’s essential to have your sewer line inspected to prevent the issue from worsening. Our sewer line experts at Chisholm Plumbing Heating & Air Conditioning can diagnose the source of the blockage and restore proper flow in your plumbing system.
Sudden Spike in Water Bills
A sudden, unexplained increase in your water bill can be another indication of a sewer line problem. If there’s a hidden leak in your sewer line, it can cause your water usage to increase without any obvious signs inside your home. Sewer line leaks often go unnoticed, as the damaged pipe is usually underground or hidden from view, making higher water bills one of the first clues that something is wrong.
Why Higher Water Bills Can Indicate a Sewer Line Issue
- Continuous Water Loss: A cracked or leaking sewer line means water is continuously escaping, leading to higher usage even if your household habits haven’t changed.
- Hidden Leaks: Unlike a visible indoor leak, a sewer line leak won’t typically show itself in the form of dripping or water damage in the home, making your water bill the only visible clue.
- Potential Property Damage: Left untreated, sewer line leaks can saturate the soil around your home, potentially leading to sinkholes or foundation issues, which can be costly to repair.
If you notice an unexpected spike in your water bills, it’s wise to have a professional evaluate your sewer line. Chisholm Plumbing Heating & Air Conditioning can perform a thorough inspection to pinpoint any leaks or damage, helping you resolve the issue quickly and prevent further costs.
