As you are probably aware, traditional pipe replacement involves digging and removing old pipes. But what if we told you there's no longer a need for all the mess? Pipe relining reinforces existing pipes from the inside, eliminating the need to dig. Think of traditional as working from the outside in, and relining as working from the inside, out.
Both options have pros and cons, depending on various factors which we will look at. We’ll break down the key differences between pipe relining and pipe replacement, helping you make an informed decision when deciding which option best suits your needs.
Pipe relining is a modern, trenchless repair method, meaning there's no need to dig up your yard, garden or driveway. Instead of replacing the entire pipe, a flexible resin-coated liner is inserted into the existing pipe, then inflated and cured to create a durable, seamless new pipe within the old one.
Pipe replacement is the traditional approach to fixing severely damaged or deteriorating pipes. It involves the plumbers digging a trench to reach the full length of your pipe, removing it, placing a new pipe in, and filling back up the trench with dirt. Very labour-intensive.
Here’s a side-by-side overview comparison of pipe relining vs pipe replacement to help you determine the best option for your situation:
As you can see from the table above, pipe relining is typically more affordable. However, costs depend on pipe length and the amount of damage. If there is a significant amount of damaged or broken pipes, there is a type of relining called pipe bursting, which costs more in line with full replacement.
Pipe replacement is more expensive due to the labour involved with accessing your pipe. And the harder it is to access, the more it will cost. For this reason, some customers dig the trench themselves to save money. The other factor that affects the cost is the price of new materials.
Choosing between both pipe relining and pipe replacement depends on several factors. As such, asking yourself the right questions can help you determine the best option for your situation.
Consider the following:
Let's dive further into each for your pipe relining project.
The severity of damage to your pipes is one of the biggest factors in deciding whether to reline or replace them.
Assessing the level of damage is the first step to help you choose the most effective and cost-efficient repair method.
The condition of your pipes plays a big role in deciding whether to reline or replace them. If they are newer pipes with minor issues, relining is your quick and cost-effective fix.
For older, worn-out pipes that are heavily cracked, corroded, or leaking in multiple places, full drainpipe replacement may be the smarter long-term investment.
We understand you may not be able to tell whether you have old or new pipes or the extent of the damage as they could be buried. In this case, call in a plumber who has specialised equipment, such as a CCTV camera to insert and inspect the condition of your pipes. They can then advise you on your next move.
If you're environmentally conscious and looking for a solution that’s easier on both your property and the environment, then pipe relining job is the way to go.
There is no need to dig up your yard, driveway, or garden. since relining repairs pipes from the inside.
Moreover, the old pipes stay in place, reducing landfill waste and the need for new materials.
Conversely, traditional pipe replacement methods involve heavy excavation, which can disturb landscaping, driveways, and nearby structures. The traditional method is much more a disruptive and resource-intensive process.
Before committing to a repair method, consider checking local regulations and permit requirements. However, it's mainly pipe replacement that often requires permits and compliance. Because of the noninvasive nature of pipe relining, it typically faces fewer regulatory hurdles.
Pipe relining solutions are typically a five-step process:
1. Inspection and Assessment – A CCTV camera is used to inspect the damaged pipe and determine if relining is the best solution.
2. Pipe Cleaning – High-pressure water jets or mechanical tools remove debris, roots, and blockages to ensure a smooth surface for relining.
3. Liner Insertion – A flexible liner impregnated with a two-part epoxy resin is inserted into the damaged pipe.
4. Expansion and Curing – The liner is expanded and left to cure, hardening to form a new, durable newly relined pipe inside the old pipe's interior surface.
5. Final Inspection – Another CCTV check ensures the relining was successful and the pipe is fully restored.
It's important to note that different plumbers may have slightly different pipe relining techniques.
While it appears pipe relining is the clear winner in a lot of areas, there are still some benefits of pipe replacement to consider. A full replacement removes severely damaged pipes instead of just reinforcing them and avoids frequent pipe repairs by fully replacing broken pipe sections. Furthermore, new pipes ensure pipes meet current building codes and regulations. Finally, regular plumbing maintenance can ensure the longevity of your new pipe.
