Pipe Relining vs Replacement: Which Is Better for BC Leaking Pipes?
Compare pipe relining (epoxy lining, CIPP) with traditional pipe replacement for repairing leaking pipes in BC properties.
Pipe Relining / CIPP
A liner coated with epoxy resin is inserted into the existing pipe and cured in place, creating a new pipe within the old one. No excavation required for access.
Pros
- No trenching or excavation needed
- Faster completion (1-2 days vs 1-2 weeks)
- Less disruptive to building finishes
- Cost-effective for long pipe sections
- Extends pipe life by 50+ years
Cons
- Cannot repair collapsed or severely damaged pipes
- Reduces pipe diameter slightly
- Requires clean pipe interior to bond properly
- Not suitable for all pipe materials
- Specialized contractor required
Traditional Pipe Replacement
The damaged pipe section is physically removed and replaced with new pipe. Requires access to the pipe location through excavation or opening walls.
Pros
- Complete replacement with new materials
- Restores full pipe diameter and flow capacity
- Can address any pipe condition issue
- No risk of liner failure
- Standard plumbing contractor can perform
Cons
- Requires excavation or wall opening
- More disruptive and time-consuming
- Higher labor cost for access and restoration
- Landscape and finish restoration adds cost
- Longer completion timeline
The Verdict
Pipe relining is ideal for accessible pipes that are structurally sound but have pinhole leaks or corrosion. Traditional replacement is necessary for collapsed pipes or where excavation access is practical. LeakInspections.ca can assess your pipe condition and recommend the best approach. Call 604-239-9934.
