Damaged and deteriorating pipes can cause a range of plumbing issues in any home. From bothersome leaks and bursts to more serious structural damage, it’s crucial to address pipe problems before they worsen.
When faced with damaged pipes, you have two main options—pipe relining or traditional pipe repair. Understanding the differences between these methods will help you choose the most suitable and cost-effective solution for your needs and budget.
Understanding Your Pipes
The most common pipe materials used in homes are copper, PVC, concrete and cast iron. Each material has weaknesses. For instance, copper is prone to pinholes, while concrete pipes crack easily. Cast iron and steel also corrode over time.
Typical problems include leaks, cracks, blockages from buildups or debris, and root intrusions in sewer pipes. Such damage can impede water flow, reduce water pressure, and lead to backups if left unchecked. Integrating pipe relining or repairing early on can preserve most pipe types well, avoiding complete replacements.
Pipe Relining
Pipe relining involves coating the inside of pipes with a thin epoxy resin to form a smooth, lasting barrier. Cameras inspect and measure the pipes before a flexible tube coated with resin is fed through the pipe system. A UV light then cures and hardens the resin. Digging is rarely needed as access points like vents or taps provide entry.
Notable perks of pipe relining include:
-
Minimal invasion: With this option, most of your yard stays in place.
-
Cost savings: Pipe relining often costs a fraction of full pipe replacements.
-
Improved water flow: You could expect a smoother interior for better water flow.
-
Applicable for varied damage: Relining is ideal even for cracks and chips, depending on the size and location.
Two main methods exist—epoxy resins cured in place or inserting a flexible pipe liner inside the host pipe. If pipes are structurally sound, relining can restore most metal and concrete pipes for 15-50 years.
Pipe Repair
For severely damaged or blocked pipes, repairs involving pipe replacement may be necessary. Common methods are patching or sealing small leaks and holes. Larger sections may need removing and replacing through digging out or ‘trenching’. Burst pipes can also be repaired by using a new pipe to replace the damaged portion. Root-cutting equipment is used as needed.
Repair suits extensive corrosion, large cracks exceeding relining capacity, incompatible or outdated pipe types without liners available or updating failing sewers. However, the drawbacks include:
-
Major digging and yard disruption
-
Higher labour and material costs
-
Invasive disturbances to home access
While sometimes unavoidable, the extent of property damage and costs associated with pipe repairs mean relining should be your first consideration. For households wanting to minimize invasion and restore pipe function cost-effectively, epoxy barriers provide an excellent solution.
Cost Comparison
On average, epoxy pipe relining in Australia could cost between AUD$250 and AUD$350 per linear metre, while replacing pipes can range from AUD$400 to AUD$700 per metre. This means that, for a 100-metre pipe, relining could save between 28% and 57% compared to replacement.
Precise costs vary on pipe size, materials, access issues and project complexity—hence, the need for upfront quotes. Ultimately, relining provides substantial cost savings except when complete pipe replacement is unavoidable.
Making The Right Choice
Now that you have a better understanding of each method and the potential costs involved, the next step is to decide. Crucial considerations for pipe relining versus repair include:
-
Pipe age and condition: Pipes over 50 years old may still be relined if the damage isn’t too severe.
-
Pipe size and material: Larger diameter pipes and certain materials like concrete can be more expensive to reline or replace.
-
Damage severity: More severe damage may require additional preparation or techniques.
-
Accessibility: Pipes buried deep under concrete or requiring extensive excavation will be more expensive to access and repair.
-
Budget: Relining suits moderate pipe damage, whereas replacement may be unavoidable for completely deteriorated pipes.
-
Timelines: Pipe relining may take just one to three days with minimal disturbance to usage.
-
Personal preferences: If you don’t mind yard digging or home usage disruptions, repairs could be a good option for your pipes.
Another critical factor to consider is where you live. Pipes in regional homes might be more challenging to reline or repair due to property laws in the area. Speaking with local contractors could help you find the best solution.
While relining handles surface damage across pipe materials well, severe corrosion or ruptures in water pipes may require replacement. Consulting qualified plumbers is necessary in these situations. They can assess damage through camera scopes and recommend the most suitable fix based on your budget and the condition of your pipes.
Conclusion
Both pipe relining and targeted repairs have merit depending on the existing pipe state and type of damage. In many cases, relining can cost-effectively prolong life for most pipe types with moderate issues. However, severely corroded pipes with substantial cracking or blockages should be replaced as needed alongside relining intact sections.
Professional inspection and quotes are invaluable for determining the ideal pipe solution for your home’s needs and constraints. Take proactive steps today to prevent minor pipe issues from turning into plumbing nightmares tomorrow!
