How Does Trenchless Water Main Replacement Work?

Replacing your main water line can be expensive as well as time-consuming and destructive to your property. Thoroughly digging up your water main can destroy much of your landscaping, including some hardscaping elements. But you may not have to go through this unpleasant process. Some experienced plumbers can perform trenchless water main replacement instead. What does this mean, and how does it work? Keep reading to find out.

What Is Trenchless Replacement?

As the name implies, trenchless water line replacement involves replacing the waterline—without the trench. But how can you replace a water line without digging it up, you ask? The process is complex and incredibly precise, so it has to be performed by a very experienced and skilled plumber. The basic steps of the process are as follows:

  1. Holes are dug at the beginning and end of the waterline. Any piping that needs to be removed to provide better access to the pipe will be removed through these holes.
  2. A tracer rod is sent through the pipe to ensure that the new piping will follow the same route
  3. A flexible poly pipe is pulled through the existing, damaged pipe.
  4. Water service is connected, and the holes are filled in.

Despite what many believe, trenchless water line replacement is not a patch job; the poly piping used in the old, metal pipes is just as reliable as the original pipework.

What Are the Benefits?

While many plumbers out there can do water main replacements, far fewer can do trenchless work. So why should you bother with finding someone who can do this type of replacement instead? Here are just some of the benefits:

  • Eliminates property damage – No digging up your lawn or flowerbeds or breaking up your concrete driveway or patio.
  • Shorter turnaround time – Standard water line replacements take between 3 and 5 days, while trenchless services can typically be done in less than 24 hours.
  • More affordable – Despite being a more specialized service, trenchless line replacement is cheaper. This is because it requires fewer labor hours (due to less excavation), fewer materials, and fewer workers.

The trenchless repair doesn’t have any drawbacks to note, as it’s the fastest, cheapest, most effective option for replacing your water mainline. However, it is worth noting that not every water main can be replaced in this way. If the terrain doesn’t allow for it or if the water main is more than 100 feet long, trenchless technology might not be an option.
