Trenchless sewer repair offers homeowners a less invasive alternative to traditional methods using excavation. However, despite its growing popularity, numerous myths and misconceptions surround this innovative technology. Let’s talk about nine common myths we regularly hear about trenchless pipe repair, debunk them, and help you make an informed decision if you are faced with a sewer lateral that needs repair or replacement.
Myth #1: Trenchless Sewer Repair is a New Technology
One of the most prevalent misconceptions about trenchless sewer repair is that it’s a new and, therefore, unproven technology. But in fact, trenchless methods have been in use since the 1970s and have steadily evolved and improved, with countless successful applications in both residential and commercial settings.
Trenchless pipe bursting actually pulls an entirely new, seamless pipe through the space occupied by the old pipe, and is therefore extremely reliable.
And CIPP (cured-in-place-pipe) trenchless pipe lining can now be done using UV epoxy curing (this is the method we choose at Service Force Plumbing), which means that the repair can be done more quickly and with guaranteed results versus the older heat-cured methods that still have some innate weaknesses. CIPP can also often be completed without any excavation at all.
Myth #2: It is More Expensive than Traditional Methods
Another common misconception is that trenchless pipe repair is significantly more expensive than traditional excavation methods. when, in fact, the actual trenchless process costs a similar amount. On top of that, traditional pipe replacement often requires extensive excavation, which can lead to additional costs for landscaping restoration, driveway repairs, and potential damage to other underground utilities.
If traditional trench excavation would damage more than just the grass in your yard, you would almost certainly save money – and hassle – by using a trenchless method if it is otherwise suited to your project.
Myth #3: It is Less Expensive than Traditional Methods
Many people believe that rather than being more expensive, trenchless pipe repair should always be cheaper than traditional sewer line lateral excavation because labor costs and time costs are reduced. However, the cost of the technology, the cost of materials, and the cost of highly trained technicians mean that the price difference can be insignificant, and once again, your individual underground situation will determine the best course of action.
It’s important for homeowners to get accurate assessments and quotes from reputable plumbing professionals before making a decision. Each situation is unique, and the most cost-effective solution will depend on the specific circumstances of your sewer line problem. A thorough inspection and evaluation by a qualified technician can help determine whether trenchless repair or traditional methods are more suitable and economical for your particular case.
Myth #4: Trenchless Pipe Repair is Only a Temporary Fix
As we mentioned above, trenchless pipe bursting pulls a new HDPE seamless pipe through the path of the existing, damaged pipe, resulting in a fix that is nearly as durable as an excavated PVC sewer pipe installation.
Trenchless pipe relining with CIPP is also – when installed correctly by expert technicians – extremely durable and long-lasting.
As long as you have chosen the correct method for your individual situation and have proven professionals do the work, trenchless sewer repairs provide a reliable, permanent solution to pipe damage.
Myth #5: Trenchless Pipe Lining is Only for Spot Repairs
A common misconception is that trenchless solutions are limited to small, localized repairs. While trenchless methods are indeed excellent for addressing specific problem areas, they are also capable of rehabilitating entire sewer lines. Trenchless pipe lining can be used to repair long sections of pipe, sometimes spanning hundreds of feet. This versatility makes trenchless technology suitable for both minor repairs and comprehensive sewer line rehabilitation projects.
Trenchless pipe replacement methods, such as pipe bursting, can even be used to replace entire sewer lines without extensive excavation. These techniques allow for the installation of new pipes with minimal surface disruption, making them ideal for properties where traditional excavation would be impractical or costly. The flexibility of trenchless solutions enables plumbing professionals to address a wide range of pipe repair and replacement needs efficiently and effectively.
Myth #6: It Doesn’t Work on Dirty or Obstructed Sewer Lines
Modern trenchless technology includes sophisticated cleaning and preparation techniques that can address even heavily soiled pipes. Before any repair or lining process begins, thorough cleaning is performed using high-pressure water jetting and mechanical cleaning tools. These methods effectively remove debris, scale, and even tree roots from the pipe interior.
Advanced inspection cameras are then used to ensure the pipe is clean and ready for repair. In cases where traditional cleaning methods are insufficient, specialized techniques like robotic cutting can be employed to remove stubborn obstructions. Once properly cleaned and prepared, even pipes that were once considered too dirty for trenchless repair can be successfully rehabilitated using methods like CIPP lining.
Myth #7: Trenchless Methods Can’t Repair Severe Damage
Another prevalent myth is that trenchless methods are only suitable for minor pipe damage. In reality, trenchless technologies can address a wide range of severe pipe issues, including significant cracks, breaks, and even collapsed sections. Advanced trenchless repair techniques, such as sectional point repairs and pipe bursting, can effectively restore or replace severely damaged pipes without the need for extensive excavation.
For instance, CIPP lining can bridge gaps and seal large cracks, effectively creating a new, structurally sound pipe within the damaged one. Similarly, trenchless pipe bursting techniques can be used as long as a cable can be pulled through the path of the previous sewer line.
There are, however, instances where damage to the line is, in fact, too severe to repair using trenchless solutions. If a significant length of the sewer lateral is collapsed, or if it is full of hard-packed debris, it may be impractical or impossible to clear the path of the old line effectively enough – or economically enough – to allow the use of a trenchless solution.
Myth #8: Trenchless Methods Don’t Work On Old Pipes
There’s a misconception that trenchless repair methods are incompatible with older sanitary sewer pipe materials or deteriorated pipes. However, trenchless technologies have been successfully applied to a wide variety of pipe materials, including clay, cast iron, concrete, and PVC, regardless of their age. In fact, trenchless methods are often ideal for rehabilitating aging infrastructure without the need for disruptive and costly excavation.
Trenchless pipe lining can effectively restore old pipes by creating a new, smooth surface within the existing pipe, improving flow and preventing future corrosion or root intrusion. For severely deteriorated pipes, trenchless pipe bursting can replace the old pipe entirely while minimizing surface disturbance. The versatility of trenchless methods makes them suitable for addressing pipe issues in both modern and historic properties, offering a valuable solution for maintaining and upgrading aging sewer systems.
Myth #9: Trenchless Repair is Always the Best Option
While trenchless sewer repair offers numerous benefits, it’s important to recognize that it’s not always the best solution for every situation. Factors such as pipe condition, location, and specific damage types can influence the most appropriate repair method. In some cases, traditional excavation might be necessary or more cost-effective, particularly for pipes located in easily accessible areas or when multiple repairs are needed along the pipe’s length.
In most cases, if the above-ground landscape is not a concern, traditional excavation for sewer line repair is still the best choice. It allows you to lay a new bed of gravel support for the pipe at just the right angle, it allows physical inspection of the exterior of the pipe before it is covered, and it allows correct and complete compaction of the surrounding soil.
