31 March 2023 Blocked Drains

As a homeowner, dealing with damaged pipes can be a daunting task. You’re faced with important decisions, such as whether to opt for pipe relining or pipe replacement. This comprehensive guide is designed to help you make the right choice by exploring the pros and cons of each method, along with other factors to consider when addressing your plumbing needs.

Pipe Relining

Pipe relining, also known as trenchless pipe repair, is a modern method of repairing damaged pipes. It involves inserting a flexible, resin-impregnated liner into the existing pipe, which is then inflated and cured to create a new pipe within the old one.

Pros of Pipe Relining

Trenchless technology: One of the main advantages of pipe relining is that it requires little to no excavation, which means minimal damage to your landscaping and property.

Time-efficient: Pipe relining is typically faster than traditional pipe replacement methods, reducing downtime and inconvenience for homeowners.

Cost-effective: With less excavation and labour required, pipe relining is often more cost-effective than pipe replacement.

Environmental impact: As pipe relining generates less waste and has a lower environmental footprint than traditional methods, it is considered a more eco-friendly option.

Durability: The new lining created during the relining process is highly resistant to corrosion and tree root intrusion, potentially extending the life of your pipes.

Cons of Pipe Relining

Limited applicability: Pipe relining may not be suitable for pipes with severe damage or collapsed sections.

Slight reduction in pipe diameter: The relining process can result in a minor reduction in the diameter of the repaired pipe, which may affect flow rates.

Material concerns: Some homeowners may have concerns about the chemicals used in the relining process and their potential impact on water quality.

Pipe Replacement

Pipe replacement involves the complete removal and replacement of the damaged pipe. This traditional method often requires extensive excavation and may cause significant disruption to your property.

Pros of Pipe Replacement

Comprehensive solution: Pipe replacement completely removes the damaged pipe, ensuring that the problem is fully addressed.

Versatility: This method is suitable for addressing all levels of pipe damage and various pipe materials.
Improved water flow: Replacing the damaged pipe with a new one can result in better water flow and pressure.

Cons of Pipe Replacement

Disruption: Pipe replacement often requires significant excavation, which can lead to damage to your landscaping and property.

Time-consuming: The process of pipe replacement can be lengthy, causing inconvenience to homeowners.

Higher costs: Due to the extensive labour and materials involved, pipe replacement can be more expensive than pipe relining.
Environmental impact: Pipe replacement generates more waste and has a higher environmental footprint than trenchless methods.

Factors to consider when choosing between Pipe Relining and Pipe Replacement

Several factors come into play when deciding whether to opt for pipe relining or pipe replacement. Some important aspects to consider include:

Extent of pipe damage: Assess the severity of the damage and whether it can be effectively addressed through relining or if replacement is necessary.

Budget constraints: Consider the costs of both methods and determine which option is more financially viable for your situation.

Property disruption: Evaluate your tolerance for potential damage to your landscaping and property during the repair process.

Environmental concerns: Consider the environmental impact of each method, especially if you prioritise eco-friendly solutions.

Pipe material and age: The type and age of your pipes may influence the most suitable repair method.

When faced with the decision between pipe relining and pipe replacement, homeowners must consider various factors, such as the extent of pipe damage, budget constraints, property disruption, and environmental impact. By understanding the pros and cons of each method, you can make an informed decision that best suits your specific situation. Always consult with a professional plumber or pipe repair specialist to assess your pipes’ condition and recommend the most appropriate solution.

Frequently asked questions – Pipe Relining v Pipe Replacement

Q: How do i know if my pipes need relining or replacement?

A: A professional plumber or pipe inspection service can assess the condition of your pipes using specialised equipment such as cameras. They will then recommend the most appropriate repair method based on the extent and nature of the damage.


Q: Can all types of pipes be relined?

A: While pipe relining is suitable for various pipe materials, including cast iron, PVC, and clay, it may not be appropriate for pipes with severe damage or collapsed sections. In such cases, pipe replacement might be the only viable option.

Q: How long does pipe relining last?

A: The lifespan of a relined pipe depends on various factors, such as the quality of materials used and the installation process. Generally, relined pipes can last up to 50 years or more, making them a durable and long-lasting solution.

Q: Does pipe relining affect water pressure?

A: Although pipe relining can result in a slight reduction in the diameter of the repaired pipe, this typically does not significantly affect water flow or pressure. In many cases, the improved structural integrity of the relined pipe can even enhance water flow and pressure.

Q: How much does pipe relining cost compared to pipe replacement?

A: The cost of pipe relining and pipe replacement depends on factors such as the length and diameter of the pipe, the complexity of the repair, and your location. Generally, pipe relining tends to be more cost-effective than pipe replacement due to the reduced labour and excavation involved. However, it’s essential to obtain quotes from multiple service providers to compare prices and choose the best option for your needs.
