What is a Trenchless Sewer Line?

If you’ve ever wondered "what is a trenchless sewer line?", you’re not alone, but it truly is simple. It’s a type of sewer line replacement that does not require digging a trench. Also known as pipe relining, it’s commonly offered by most plumbing companies and prevents homeowners landscaping from being disrupted or even destroyed.


How Does Trenchless Sewer Line Replacement Work?


If there’s no digging needed, how does trenchless sewer line replacement work? Basically, the pipe is not being replaced but relined from the inside, sealing all leaks in the old pipe. There are primarily two types of trenchless sewer line replacements called Cured in Place Pipe (CIPP) and Spray in Pipe Liners.

CIPP or Cured in Place Pipe is a process in which a felt lining soaked in epoxy is pulled through the damaged sewer pipe and hardens in place. It takes approximately 24 hours for cured in place pipes to fully cure before a unique cutting tool is used to open any connections within the area being repaired. Once completed, a video inspection must be made to ensure the pipe relining fits properly. This type of trenchless sewer repair typically lasts longer than a traditional pipe replacement.

Spray in Pipe Liners are a newer version of trenchless sewer repair that plumbing companies have the option to use so long as the length of pipe being repaired is less than 20 feet. A special pressurized nozzle is fed through the damaged sewer line spraying the new pipe liner. The spray in pipe liner dries quickly and does not require the additional cutting of connections.


How Much Does Trenchless Sewer Line Repair Cost?


Plumbing companies usually price trenchless sewer repairs based on the length of the damaged pipe and the type of trenchless repair they perform. The average trenchless sewer repair in Houston from Nick’s Plumbing can cost between $1800 - $5000.
