In this article, we’ll talk about pipe relining as opposed to. pipe replacement, and find out which one suits your requirements more.

The term "pipe relining" is used to describe the process of repairing pipes.

Pipe relining or Cured-In-Place Pipe (CIPP) Lining is a state-of-the-art repair process that provides a cost-effective, fast solution for repairing damaged pipelines.

Here’s how it works:

  1. A technician cleans the pipeline with high-pressure jetting or mechanical cleaning.
  2. They then apply epoxy resin made of polyester or fiberglass liner inside the pipeline.
  3. The liner is cured by forming a new lining in the old pipeline that’s just as strong as a brand new one.

Advantages Pipe Relining

  • Time-efficient – It typically takes only 2 to three hours for the entire process compared with excavating for many days using traditional pipe replacement methods.
  • Cost-effective because there is no excavation or removal needed in the pipe relining process It can save you nearly 50% of the cost you’d have to pay for repairs that are traditional.
  • Durability – The new liner made by pipe relining could last up to 50 years!

The cons of Pipe Relining

  • Not suitable for very damaged pipes. If you have significant damage such as cracks, collapses or joints that are misaligned in your sewer line then pipe relining may not be possible.

What exactly is Pipe Replacement?

Pipe replacement involves digging up portions of the yard/sidewalk/driveway where underground pipes are located. The areas may contain broken pipes, or very damaged ones due to lack of maintenance or age.

The following steps make up the majority of traditional replacements for pipes:

  1. A team of excavation workers digs access to the deteriorated underground pipe.
  2. The pipeline was ripped off and dug out producing much debris that must be cleared away.
  3. Then, they construct a new pipeline in place of the one they had previously installed.

Benefits of Pipe Replacement

  • Suitable for severely damaged pipes In the event that you need to replace pipes that have significant corrosion or damage, pipe replacement is the most effective option.
  • Long-lasting – The latest pipeline replaced with pipe has a lengthy lifespan (75 to 100 years) which makes it a great choice for homeowners in search of the best solution for their home.

Cons of Pipe Replacement

  • The work of excavation required to replace pipes can be costly and time-consuming.
  • The process is time-consuming. Traditional pipe replacements could take several weeks, based on the scope of work and depth of excavations required.

Which option should you pick?

The decision of replacement or relining your pipes is largely based on the degree of damage caused. If your pipes suffer from minor damages like cracks or leaks of a minor size, it is likely that relining is the better option since it’s less costly and also quicker than conventional replacements.

However, if there are serious injuries, like breaks or collapses and breaks, you must consider traditional pipe replacement although it could be more costly and takes longer.

Frequently Asked Questions

What is pipe relining?

Relining a pipe is a process that involves creating a new pipe within the existing damaged pipe. It is accomplished by inserting a flexible liner in the old pipe and then the process of curing it. Once it is cured, the new pipe has no joints or seams, which enhances the structural integrity of the pipe.

What does traditional pipe replacement differ from pipe relining?

Traditional pipe replacement involves digging and physically removing old pipes, and then replacing them with brand new ones. However, pipe relining doesn’t require excavation; instead it’s accomplished with the help of technology, which allows pipeline repair without digging up large portions of land.

Which option is less expensive: liner relining or conventional pipe replacement?

Pipe relining generally costs less than traditional methods of pipeline repair as there is no cost related to excavation or other procedures needed for removing and replacing old pipes.

All kinds of pipes can be changed?

Not all types of pipes are relined effectively. The plumber will need to examine the situation to determine if it is feasible to line the particular kind of pipes. But, the majority of contemporary pipes are lined with this method.

How long will the process of pipe relining take?

The exact time required for the process depends on different variables like location, environmental conditions, and type of damage. However the average Pipe Relining job usually takes 2-3 days, depending on how many meters need to be lined..
