Have you heard about pipe relining? Are you currently weighing the options between relining and repiping your plumbing system?

We have all the answers you need to assist you in making the best choice for your home's plumbing, focusing on pipe relining in fresh water lines entering your home.

In this article, we will delve into the process of pipe relining, defining what it is, highlighting the main differences between pipe relining and repiping, and explaining why repiping consistently stands out as the superior choice for your home's plumbing system.

What Is Pipe Relining?

Pipe relining is a plumbing technique designed to address issues within existing pipelines without the need for extensive replacements.

During the pipe relining process, a flexible and durable resin-coated liner is inserted into the damaged or deteriorating pipe, creating a new pipe within the original one.

Once the damaged section is identified, it is cleaned, and the resin-coated liner is introduced into the pipe through methods such as inversion or pulling through:

  • Inversion Method: This involves inserting a resin-coated liner turned inside out into a damaged pipe, flipping it right-side-out as it progresses, and curing the resin for reinforcement.
  • Pulling Through Method: In this approach, a resin-coated liner is pulled through a damaged pipe, coating its interior and conforming to its shape, with the resin undergoing curing for durability.

The resin undergoes a curing process, typically facilitated by steam, heat, or UV light, transforming it into a solid lining.

Pipe relining is particularly common in situations where traditional pipe replacement would be excessively disruptive and costly, such as in drainage systems and sewer lines.


What Is The Difference Between Pipe Relining and Repiping?

Despite providing similar services, pipe relining and repiping are inherently different.

Pipe relining is a targeted and sometimes less disruptive alternative to repiping, making it a strong choice for pipes that may cause significant disruptions if they are repiped, such as sewer lines and drainage systems.

Repiping is a comprehensive solution that involves the complete replacement of existing pipes, providing an entirely new plumbing infrastructure. This method is particularly advantageous in situations where widespread issues, such as corrosion, leaks, or deteriorating materials, are prevalent. We have a detailed article on the most frequently asked questions about repiping.

Pipe Relining vs. Repiping: Why You Should Choose Repiping

Although pipe relining is a useful plumbing technique, when it comes to the fresh water lines entering your home, you should always choose a full home repipe over pipe relining.

Repiping addresses not only immediate concerns but also mitigates potential future issues that might arise with aging or deteriorating pipes.

While pipe relining may fix temporary problems in your plumbing, it won't address the effects of systemic plumbing issues in your home. Other plumbing issues such as outdated CPVC pipingold polybutylene pipesleaks under slabspinhole copper leaks, or failing galvanized plumbing will require repiping in order to permanently solve the problem.

Here at Repipe Specialists, our full home repipes are designed for efficiency, ensuring a smoother repiping process. We have perfected our One-Stop Repipe™ process and can typically complete a full home repipe in just one or two days.
