Unscrupulous plumbing contractors in NYC tout trenchless sewer repair as a less invasive solution than other methods. With this process, the plumber inserts a flexible lining material coated with resin into the damaged pipe and inflates it to conform to the pipe’s interior. Then, the resin hardens, forming a new pipe within the old one.
Supposedly, this non-invasive method rehabilitates pipes. So, why is it illegal in NYC? Find out four reasons why trenchless plumbing is not permitted in NYC.
Fails To Address Root Causes
Trenchless plumbing does not resolve the underlying issues that often lead to sewer line problems. For example, it won’t fix back-pitched pipes, root infestations, or separated pipes. Instead, the plastic liner merely covers them up. This can give homeowners a false sense of security, thinking the issues have been resolved.
Because the trenchless method doesn’t address common problems, it’s ultimately ineffective. It’s only a matter of time before the initial problem presents itself again, which can lead to more severe and costly repairs down the line.
Presents a Risk of the Liner Becoming Stuck
Another reason trenchless plumbing is not permitted in NYC is that the liner can get stuck rather than extend to form a new pipe. Damaged pipes often have irregularities or obstructions that can snag the liner during insertion. Getting the liner stuck can also exacerbate existing sewer line issues.
When this happens, it can cause thousands of dollars in damage and require extensive repairs to remove the stuck liner. Licensed sewer contractors must use techniques that reliably restore the system’s functionality and do not cause further deterioration.
Reduces Pipe Diameter
One of the major drawbacks of trenchless plumbing is that it decreases the diameter of the sewer line. Pipes naturally accumulate debris over time, which already reduces their internal diameter. Adding a liner further constricts the pipe.
This reduction in diameter significantly increases the likelihood of future clogs. The reduced space makes it easier for debris to accumulate and harder for waste to flow freely, defeating the purpose of the repair. Consequently, homeowners may find themselves dealing with frequent blockages.
Cuts Off Connected Lines
A trenchless plumbing liner does not account for other drain connections that may link to your sewer line. The liner can run the length of the pipe it is inserted into and cut off connections to leader lines, driveway drains, and storm sewer connections.
This oversight can lead to serious complications. For instance, imagine discovering that your driveway drain no longer works after the liner has been installed. The inconvenience and additional repair costs this would incur can be significant.
Trenchless plumbing methods, often promoted as less invasive solutions, fail to address underlying issues like root infestations and back-pitched pipes, offering only a temporary fix. Not to mention, the liner could get stuck and cause extensive damage that requires costly repairs. Additionally, trenchless plumbing reduces the pipe’s diameter, which significantly increases the likelihood of clogs and future blockages. Finally, it can cut off vital connections to other drain lines, leading to further complications and additional repair costs.
