Sewer backups are a homeowner’s nightmare, leading to costly repairs, unpleasant odors, and potential health hazards. Understanding the common causes of these backups is crucial to protect your home. From aging sewer systems to improper waste disposal, various factors can disrupt the smooth operation of your plumbing. However, by implementing a few strategic practices recommended by our experts at Reliable Services, you can significantly reduce the risk of sewer backups and maintain a healthy, efficient plumbing system.
Causes of Sewer Backups
Tree Root Infiltration
While trees add beauty and value to your property, their roots can be a hidden threat to your plumbing system. Tree roots naturally seek out water sources as they grow, and your sewer pipes are a prime target. As roots find their way into small cracks or joints in your sewer lines, they expand, causing significant blockages and even breaking pipes over time.
Signs of root infiltration can vary, but some common indicators include slow drains, gurgling noises from toilets, or recurring clogs that seem to have no apparent cause. Root infiltration can lead to severe damage if left unchecked, requiring extensive repairs or even full pipe replacements.
Clogged Pipes
Over time, everyday materials like grease, hair, soap scum, and food particles can accumulate in your pipes, creating stubborn blockages that prevent wastewater from flowing freely. While clogs can occur in any part of your plumbing system, they are especially problematic in the sewer line, where multiple household drains converge.
The impact of clogged pipes on your sewer system can be severe. Minor clogs might cause slow drains or temporary backups, but as the blockage worsens, it can obstruct the sewer line entirely. This can result in wastewater backing up into your home, causing unpleasant odors, potential water damage, and even health hazards due to contamination.
Aging Sewer Systems
Aging sewer systems are a significant cause of backups, particularly in older homes or neighborhoods. As sewer pipes age, they become more susceptible to wear and tear, which can lead to a host of problems. Common materials used in older sewer systems, such as clay, cast iron, or even Orangeburg (a type of bitumen pipe), have a limited lifespan. Over time, these materials can deteriorate, crack, or collapse.
The problems associated with aging sewer systems go beyond simple wear and tear. Older pipes are often more vulnerable to tree root infiltration, shifting soil, and other environmental factors. As these pipes degrade, they may develop leaks, sagging sections, or complete breaks, all of which can disrupt the flow of wastewater and significantly damage your property.
Heavy Rainfall and Flooding
Heavy rainfall and flooding can overwhelm even the most robust sewer systems, leading to backups that can cause significant damage to your home. When there is excessive water in a short period, the sewer system can struggle to handle the increased volume. This is especially true in areas where the stormwater and sewer systems are combined. As the system becomes overloaded, the excess water has nowhere to go, and it can start to back up into homes through floor drains, toilets, and sinks.
The consequences of system overload due to heavy rainfall and flooding can be severe. In addition to the immediate mess and damage caused by backed-up sewage, there is also the risk of contamination, which can pose serious health hazards. Floodwaters often contain bacteria, viruses, and other harmful pathogens, making it critical to address sewer backups promptly and thoroughly.
Structural Damage
Structural damage to sewer pipes is a significant cause of sewer backups, often resulting from factors like shifting soil, ground settling, or nearby construction. These forces can cause pipes to crack, break, or even collapse, obstructing the flow of wastewater and leading to blockages and backups into your home. The natural movement of the ground, whether due to weather changes, erosion, or the weight of heavy construction equipment, increases pressure on the pipes, making them more susceptible to damage.
Older pipes, particularly those made from brittle materials like clay or cast iron, are especially vulnerable to these issues. When a pipe is compromised, the damage can go beyond just a backup; cracks and breaks allow tree roots to infiltrate the system, exacerbating blockages. Additionally, leaks from damaged pipes can attract pests and lead to soil contamination around your property.
Improper Disposal of Waste
Improper waste disposal is a major cause of sewer backups, but it can be easily prevented with proper practices. Many people unknowingly contribute to sewer problems by flushing or pouring items down the drain that shouldn’t be there.
Common culprits include grease, wipes, paper towels, feminine hygiene products, diapers, and food waste like coffee grounds or eggshells. Grease is particularly problematic; it may flow easily when hot, but it solidifies as it cools, sticking to the walls of your pipes and leading to stubborn blockages. “Flushable” wipes and other non-biodegradable items also pose a significant risk, as they don’t break down like toilet paper and can accumulate in sewer lines, creating large obstructions.
Over time, these materials can combine with other debris to form major blockages that disrupt your entire plumbing system.
Prevention Tips
Regular Maintenance and Inspections
Like routine check-ups for your car, your sewer lines need periodic attention to catch potential problems before they escalate. Early detection of small cracks, root infiltration, or debris buildup can prevent major blockages and costly emergency repairs.
At Reliable Services, we use specialized tools to thoroughly inspect your sewer pipes, identifying problems that might not yet be visible. Based on the findings, we can recommend maintenance measures like hydrojetting to clear debris or repairs to fix damaged sections.
The frequency of inspections depends on factors such as the age of your home, the type of sewer system, and the presence of nearby trees. Generally, it’s recommended that your sewer system be inspected every 1-2 years.
Proper Waste Disposal
Never pour grease, fats, or oils down the sink. Instead, collect grease in a container and dispose of it in the trash. Similarly, avoid flushing items like wipes, paper towels, feminine hygiene products, and diapers, even if labeled as flushable. These items don’t break down easily and can cause severe blockages in your sewer lines. Always dispose of them in the trash.
For food waste, scrape plates into the trash or compost bin before washing. Avoid putting fibrous or starchy foods like potato peels, rice, coffee grounds, eggshells, or pasta down the garbage disposal, as they can create clogs.
Additionally, use drain screens and traps to catch hair and food particles before they enter your pipes. Regularly clean these screens and traps to keep them effective.
Tree Root Management
To manage tree roots effectively, be strategic about where you plant trees on your property. Avoid planting trees and large shrubs near sewer lines, and consult with a professional to identify the location of underground pipes. Choose tree species with less aggressive root systems, as trees like maple, willow, and oak have extensive roots that should be planted far from sewer lines.
In addition to careful planting, consider using root barriers. These physical barriers, installed underground between trees and sewer lines, redirect roots away from pipes, preventing blockages. Root barriers are particularly helpful for properties with existing trees near sewer lines.
For existing trees that pose a risk, chemical treatments can help. Herbicides that slow or stop root growth can create a buffer zone around your pipes. Use these chemicals carefully and follow professional recommendations to avoid harming your trees and the environment.
Upgrading Plumbing Systems
Upgrading your plumbing system is a proactive step to reduce the risk of sewer backups, especially in older homes with outdated pipes. Over time, pipes can deteriorate, becoming prone to cracks, leaks, and blockages. Investing in modern plumbing materials and technologies enhances your sewer system’s durability and efficiency, protecting your home from costly issues.
Replacing old pipes made from materials like clay, cast iron, or Orangeburg with modern options such as PVC, PEX, or HDPE offers greater strength and resistance to corrosion. Modern plumbing systems also benefit from trenchless technology, allowing pipe replacement or repair with minimal excavation, saving time and reducing disruption.
Installing Backwater Valves
Installing a backwater valve is a highly effective way to protect your home from sewer backups, especially during heavy rainfall or flooding. This device prevents sewage from flowing back into your home by blocking reverse flow in your sewer line, a crucial safeguard in areas where the municipal system can become overwhelmed.
Backwater valves allow wastewater to flow out of your home but close automatically if reverse flow is detected, keeping your basement and lower levels safe from contamination and water damage. This protective barrier can save you from the costly and stressful experience of dealing with a sewer backup.
Installing a backwater valve is particularly recommended for homes that have experienced backups, are in flood-prone areas, or have plumbing fixtures below street level. The installation, typically done by a professional, involves placing the valve in the main sewer line. The cost is modest compared to the potential damage, making it a wise investment for long-term protection and peace of mind.
Managing Rainwater Runoff
Rain barrels are among the most effective ways to manage runoff. These simple containers collect and store rainwater from your roof, which can then be used for gardening or other non-potable needs. By capturing rainwater, you reduce the volume entering the sewer system during heavy storms, minimizing the risk of backups. Rain barrels are easy to install and maintain, making them a practical choice for homeowners.
Proper grading of your property is also crucial to ensure that rainwater flows away from your foundation. Poor grading can lead to water pooling around your home, increasing the risk of basement flooding or sewer overload. Regrading or installing French drains can help direct water away from your home.
Permeable pavements are another solution, allowing water to pass through and be absorbed into the ground, reducing runoff. Additionally, maintaining gutters and downspouts to direct water away from your property is essential.
Finally, installing a sump pump in your basement adds an extra layer of protection. It automatically removes water that accumulates and prevents flooding or sewer backups
