How to Tell if Your Sewer Line Needs Repair or Replacement

Detect Sewer Line Issues Early

Owning a home is a huge responsibility, and it’s important to properly take care of your sewage system. Even when there are minor issues, it may bring unpleasant odors, slower drains, and sewage backups into your house. This issue can also lead to expensive property damage if you choose to ignore it. Many families decide not to repair or replace their sewer line until problems arise. By addressing issues as soon as possible, though, you can save yourself time and stress. As a homeowner, it is important to understand the difference between needing to repair or replace your sewer line. Although it depends on how damaged your sewer line is, you might simply need to have it repaired. It’s important to spot the signs of sewer line damage in order to figure out if you need to call an expert for repairs or replacements. 

  ` The Purpose of Sewer Line Detection

While learning about the importance of detecting a warning sign of sewer line issues, you should also seek to understand the purpose of it. In your home, main sewer lines carry wastewater out of your plumbing system. Moreover, wasterwater flows from your property into the city sewer system or a septic tank. Any time you use the toilet, turn on the sink, let the shower run, or wash clothes, wastewater will travel into and out of the sewer line. Considering how the main sewer line is connected to almost all the drains in your house, even slight destruction may impact your plumbing network. Tiny cracks or blockages could cause water flow to slow down. This can lead to problems with toilets, sinks, showers, and appliances. 

         Multiple Drains Backed Up

One indicator that your sewer line may need attention is if multiple drains are backing up. While one clog isn’t considered a major issue, if there are multiple fixtures that are backed up, you should call a professional. This problem could lead wastewater to not flow properly into and out of your home. Slow drains throughout the house are another sign it’s necessary to contact an expert. While a slow drain in one part of the home typically indicates an issue with just that particular drain or plumbing fixture, problems with multiple drains could be a sign of trouble with the main sewer line.  

             Causes of Slow Drains 

It’s crucial to keep in mind how the most common causes of single slow drains include hair, soap scum, grease, or food debris stuck in the drain. Another key indicator of a sewer line problem is frequent toilet backups. If your toilet keeps getting clogged on a regular basis after using a plunger or snaking, this may indicate a problem with your main sewer line. Unpleasant sewage odors are another indicator of trouble with the main sewer line. 

              Foul Odors

If you find sewer gas smells, it could indicate there is a crack or leak in the sewer pipe. When there are cracks or leaks, it creates an opening that lets sewer gases enter the home rather than remain concealed inside the drainage system. During your homeowning experience, you may find trouble with your main sewer line based on wet spots or unusually green grass in the yard due to extra moisture from underground leaks. Instead of being kept inside the pipe, wastewater trickles into the soil. In this situation, you might also find your grass growing faster from the additional moisture. 

    Gurgling Sounds

Hearing gurgling sounds from drains or toilets is a key indication of a damaged sewer line as well. Here’s how it happens - blockages or destroyed sewer lines disrupt how water normally flows. This occurs because air gets stuck inside the pipes due to blockages or defective sewer lines. It leads air to escape into a nearby drain or toilet. Once this happens, it creates the bubbling sound you might be hearing. One key point to take away from this is that if your drainage system is gurgling nonstop, it could be indicative of issues with sewer lines or another appliance in your house. Just so you understand the science of it all, what happens is that blockages and destroyed sewer lines interfere with how air and wastewater flows through your plumbing lines. Instead of being carried away, the air backs up into the toilet bowl. It causes a bubbling sound. If you keep hearing gurgling sounds that don’t stop, you should call a professional.

      Tree Root Intrusion

Now that you’re familiar with the common signs you need a sewer line repair or a replacement, let’s go over what causes this issue. One major cause is tree root intrusion. In your home, if there are small cracks that form in the sewer line, little amounts of water could leak into the soil. Once tree roots make their way into sewer lines, they grow within the pipes, which creates blockages and restricts the flow of wastewater. When the roots get bigger, it puts greater pressure on the sewer line. This causes cracks to increase in size, raising risks for serious destruction. While the list of issues tree root intrusion brings is quite long, the most common ones include leaks, clogs, and total pipe collapse. Ignoring this issue could result in expensive sewer line repairs or you might even need a replacement. 

Aging Pipes

One other major problem that leads to sewer line damage is aging pipes. For those of you who have older pipes, it’s important to know they naturally deteriorate. If your pipes are made of clay or cast iron, this is especially true. Once the pipes become older, it’s likelier for them to eventually start cracking, corroding, or collapsing. This increases risks for a leak, blockage, and a broken sewer line. This happens when older pipes weaken over time, causing them to be more vulnerable to damage as the ground shifts. While you’re dealing with iron pipes specifcally, exposure to wastewater and minerals over a long period of time may cause them to degrade.  If you’re noticing any damage in your pipes, you should call a professional as soon as you possibly can. 

  What Causes Sewer Line Damage? 

The list of common reasons for sewer line destruction continues. When the ground shifts, this is considered another reason for damaged sewer pipes. Moisture levels, outdoor temperature, and soil erosion impact how much the ground moves. Another factor that impacts ground movement is construction. While the ground is moving, it creates pressure on sewer pipes. At some point, this leads to cracks, separation at the joints, or collapsing. As this occurs, joints become misaligned and the pipes begin to sag. Older clay or cast iron are considered rigid materials, and they are more vulnerable to cracking. Since this material isn’t very flexible, it doesn’t adjust to ground movement. This makes them likelier to crack under pressure. After a crack forms, wastewater leaks out of pipes, letting in soil, tree roots, and debris. It increases risks for blockage and other types of destruction. To avoid expensive repairs, call a professional and get your sewer line fixed right away. 

Grease and Sewer Line Issues

Among the many reasons for a damaged sewer line, grease, debris, and foreign objects are culprits as well. Buildup can create severe blockages and increase pressure, which damages your plumbing system. When grease is poured down the drain, it can cause clogs because it melts and flows deep inside the pipes, solidifying once it cools. Once it hardens, it traps pieces of food and buildup. It slowly reduces the size of the pipe until blockages occur. This is sometimes called a fatberg, which is a large blockage - as big as a rock. While trying to learn about the science behind this, it might be tricky to understand, so let’s make it simple. For example, if you’re cooking with oils, butter, or meat fats, they’re typically warm or liquid. Grease cools off as it continues to travel into the sewer system. Oil and water don’t blend well together, causing the grease to float in the dirty water. It sticks to the inner walls of the pipes, which causes hair, wipes, and food scraps to be trapped inside, contributing to buildup. In your home, you can prevent blockages by choosing to not pour grease into the drain. Call a technician if your drain is slow or you find other problems with your sewer line. 

Collapsed Pipes or Corrosion

One other sign your sewer line needs to be repaired is if you notice collapsed pipes or corrosion. If your pipes are severely damaged, they may fail completely at a certain point. Exposure to wastewater, moisture, oxygen, and other chemicals results in corrosion, which usually happens after a long period of time. These materials react with the metal, leading the pipes to become rusted and worn. Ignoring this issue can lead to severge damage. Moreover, pipes will become thinner and weaker. Developing cracks and leaks is something that happens if you ignore the corrosion. Once a crack or leak forms, it causes water to escape into the soil in your backyard or lawn. After noticing this issue, you should call a plumber to make a repair before it’s too late. 

Figuring Out if You Need Sewer Line Repair or Replacement

While trying to figure out whether you need sewer line repair or replacement, this depends on many different factors. Instead of replacing it, it may only be necessary to fix it if the damage is only in one place rather than in multiple sections of the pipes. If you just notice minor cracks in the pipes, doing a repair could be enough. Another circumstance where a replacement may not be necessary is if you’re dealing with small root intrusion. Since these roots are removable, you are in the clear. If the pipe structure is normally stable, repairs wouldn’t be necessary in this situation either.

  Sewer Line Damage Diagnosis

During your homeowning journey, it’s important to learn about how technicians diagnose sewer line problems. In order to perform a proper inspection, specialists often use a sewer camera. It’s a tool that allows plumbers to inspect the inner surface of the sewer line before digging begins. Because of this type of equipment, technicians won’t have to dig up your yard. While a technician uses these tools, what happens is that a tiny camera that works underwater attaches to an adjustable cable, which gets inserted into sewer pipes. After inserting it into the sewer line, it lets technicians see live footage from the camera. This allows specialists to find where exactly the damage is and identify issues such as a crack, blockage, root intrusion, corrosion, and collapsed pipes. Using this camera also helps the technician avoid repairing areas that aren’t damaged in any way.

  Avoid Future Sewer Lines Problems 

For those of you who own a home, just remember there are ways you can prevent future sewer line problems. One way to do this is to schedule routine inspections. Don’t flush wipes, paper towels, or hygiene products. Instead of pouring grease down the drain, throw it out in the trash, on a paper towel, or a spatula. Be careful about planting trees near sewer lines to avoid root intrusion. If you’re experiencing a minor issue, you should definitely address it right away to prevent it from turning into a major disaster.

  Prevent Sewer Line Damage From Impacting Your Home

Discovering whether or not your sewer line needs to be repaired or replaced is an important part of being a homeowner. You are now familiar with the warning signs, such as multiple drains being backed up or slow, frequent toilet backups, unpleasant sewage odors, wet spots or unusually green grass, gurgling sounds coming from drains or toilets. Acting early before small problems become major repairs is going to save you more money than you can ever imagine. The best way to tell if you need a repair or replacement is to call a professional for an inspection. That’s why you should contact a plumber if you notice any of these symptoms. Before you know it, your sewer line will be good as new.
