Common Causes of Sewer Line Damage

Common Causes of Sewer Line Damage

Sewer line damage is a significant concern for homeowners and businesses alike, causing not only inconvenience but also potential health hazards and costly repairs. Your home's sewer lines may be out of sight, but they shouldn't be out of mind or else you might end up with more pressing problems.

Understanding the common causes of sewer line damage is essential for every homeowner. From tree roots to aging pipes, this blog will delve into the factors that can lead to sewer line issues. By gaining insight into these causes, you can take proactive steps to protect your plumbing system and prevent costly repairs!

1. Aging and Corrosion

A key factor contributing to sewer line damage is the natural process of aging and corrosion. The longevity of sewer lines is largely determined by the type and quality of the materials used in the pipes. For instance, cast iron pipes, typically found in older homes, can last anywhere from 75 to 100 years. On the other hand, PVC pipes, which are commonly used in modern installations, have the potential to last indefinitely under ideal conditions.

As pipes age, they gradually deteriorate due to constant exposure to water and waste flow, leading to internal corrosion. This corrosion can slowly compromise the structure of the pipe, diminishing its capacity and potentially causing leaks or complete pipe failures.

Furthermore, if the water flowing through the pipes is highly acidic or alkaline, it can accelerate corrosion, particularly in metal pipes. The damage caused by corrosion not only weakens the structural integrity of the sewer lines but can also cause blockages due to the build-up of corroded pipe materials. As a result, it's essential to carry out regular inspections and maintenance of sewer lines, especially in older properties, to detect and address any damage in its early stages.

2. Blockages and Inappropriate Items

Sewer line damage often results from the accumulation of non-degradable or slow-degrading items, leading to stubborn blockages that hinder the seamless flow of sewage. These items, which are not designed to break down as efficiently as toilet paper and human waste, can cause significant blockages in the sewer system.

Take, for instance, disposable wipes. Despite some being labeled as flushable, they can contribute to the formation of substantial blockages. Other culprits include sanitary products, baby diapers, paper towels, and fats, oils, and greases.

Blockages can put excessive pressure on the pipe walls, potentially causing them to weaken, crack, or break. This can lead to expensive repair or replacement costs. Therefore, it's crucial for property owners to be mindful of what goes down their drains and toilets.

Moreover, severe blockages can lead to a backflow, a distressing scenario where sewage reverses direction and flows back into homes or businesses. Regular inspections and clean-ups can help avoid such situations. Proper trash disposal is key to maintaining a functional and long-lasting sewer system.

3. Tree Root Invasion

Another prevalent cause of sewer line damage is the invasion of tree roots. In their quest for moisture and nutrients, roots can infiltrate sewer lines through any available cracks, joints, or openings, leading to blockages or significant damage.

Consider the scenario where roots gain access to your sewer lines. They can multiply and expand swiftly, causing substantial damage to your sewage system. This can result in slow drainage, frequent sewer backups, and, in extreme cases, total system failure if not addressed in a timely manner.

While temporary relief can be achieved by cleaning the blockage, a long-term solution often requires either root remediation or sewer line replacement. Installing root barriers can also help deter roots from encroaching on sewer lines.

Planning is key when planting trees near sewer lines. Some tree species, due to their aggressive root systems, pose a greater threat to sewer lines. Therefore, it's essential to select trees and plants with less invasive root systems or plant them at a safe distance from your sewer lines. This foresight can help mitigate potential root invasions and save you from costly repairs.

4. Ground and Temperature-Related Changes

Environmental factors such as ground movements and temperature fluctuations can significantly contribute to sewer line damage. These elements can compromise the structural integrity of sewer lines, leading to potential leaks or even total collapse.

Ground movements, including landslides and earthquakes, exert immense pressure on sewer lines. This pressure can result in cracks, breaks, or in severe cases, complete collapse. This issue is particularly prevalent in areas with unstable soil conditions or regions undergoing extensive construction work.

Temperature fluctuations also pose a threat to sewer lines. In colder climates, the freeze-thaw cycle causes the ground to expand and contract, potentially leading to sewer line rupture or buckling. Conversely, excessively high temperatures can dry out the ground, causing it to shift and potentially damage the sewer lines. Extreme heat can also deform plastic PVC pipes.

Preventive measures such as insulating sewer pipes in colder climates, monitoring soil stability in areas prone to ground shifts, and conducting regular inspections can mitigate these risks. However, professional services are often necessary to accurately diagnose and repair such damages.

5. Improper Installation and Lack of Maintenance

Another significant cause of sewer line damage is improper installation and inadequate maintenance. These factors can lead to frequent issues and costly repairs.

Improper installation of sewer lines can create a host of problems. These can include the use of unsuitable materials for the specific soil or landscape, faulty pipe joints, incorrect line slopes, or insufficient pipe supports.

Even a well-installed sewer line system can deteriorate without regular inspections and maintenance. Neglecting maintenance can allow minor issues, such as small blockages or leaks, to escalate into major problems like sewage backups or pipe collapses.

Regular inspections and timely maintenance can help identify potential problems early, saving significant repair costs in the long run. For example, routine sewer line cleaning can prevent the build-up of solids that could lead to clogs.

It is highly recommended to engage qualified professionals during the installation process to ensure the sewer system is set up correctly. This can significantly reduce the likelihood of future sewer line damage. Similarly, routine maintenance by professionals can help detect and resolve issues before they become major problems, ensuring the longevity and functionality of your sewer lines.

6. Heavy Vehicle Traffic Over Ground

The impact of heavy vehicles traversing the ground above sewer lines can lead to significant damage. These pipelines, not designed to bear excessive weight, can fracture or even collapse under the constant stress of such traffic. The soil surrounding the pipes may compact due to this pressure, causing additional strain on the sewer lines. This can deform the pipes, restricting the internal flow. The extent of the damage is often proportional to the weight and frequency of the traffic above.

This issue is particularly prevalent in urban environments where the underground infrastructure is dense, and the overlying traffic is heavy. In such cases, frequent repairs or replacements may be necessary if the heavy traffic isn't diverted from the sewer lines.

To prevent this, sewer lines should ideally not be placed under areas of heavy traffic such as driveways, parking lots, or roads. If such placement is unavoidable, consider rerouting the line or reducing the weight bearing on these spots. A professional plumber can provide a comprehensive plan to mitigate the effects of heavy traffic on sewer lines.

7. Pipe Bellies

Pipe bellies, or sagging sections in sewer lines, are a frequent source of sewer line damage. These occur when a section of the pipe slopes downward, creating a dip or low spot due to soil conditions, ground shifts, or improper installation.

These sagging sections can lead to significant issues as they become collection points for wastewater and solids, causing repeated blockages. The accumulated waste and water exert additional pressure on the sagging section, increasing the likelihood of a pipe rupture. Over time, these blockages can cause extensive damage and may even result in a complete system failure.

Identifying a pipe belly can be a challenge. Often, signs such as recurring sewer backups or slow drainage are indicative of this problem. If these symptoms persist despite efforts to clear blockages, it may suggest the presence of a pipe belly.

A professional inspection, typically involving a sewer camera, is the most effective method to confirm and locate a pipe belly. The usual remedy involves excavating the area and repairing or replacing the sagging section of the sewer line. Awareness of risk factors and ensuring professional installation can help prevent the formation of pipe bellies.

8. Water Hammer Phenomenon

Often underestimated, the Water Hammer Phenomenon, or hydraulic shock, is a significant contributor to sewer line damage. This event transpires when the water flow within a pipe is abruptly stopped, generating a shockwave that applies intense pressure on the entire system.

Imagine turning off your faucet suddenly and hearing a loud thump or bang. That's the water hammer phenomenon in action. This abrupt halt in water flow creates a shockwave, much like a sonic boom, that can wreak havoc on your sewer lines over time.

The persistent onslaught of these hydraulic shockwaves can instigate a series of problems for your sewer lines. They can cause cracks or fractures, trigger leaks at the joints, and in more extreme cases, lead to pipe bursts. The relentless pressure can also displace pipes, causing 'loose joints' that allow wastewater to seep out, potentially leading to soil erosion or even sinkholes.

Key indicators of water hammer include a distinct banging or thumping sound when a faucet or appliance is abruptly turned off, unusual vibrations in the piping system, or observable pipe damage.

Fortunately, the damaging effects of water hammer can be mitigated. Installing air chambers or pressure-reducing valves can absorb the shockwave, lessening its impact on the pipes. Regular maintenance and inspections can also help identify early signs of water hammer, allowing for preventative action.

Given the severe damage that can result from hydraulic shock, it's essential to monitor for such occurrences, particularly in systems with high usage or pressure. If you suspect that water hammer is affecting your piping system, it's advisable to seek the expertise of a professional plumber for a thorough examination and appropriate intervention.
