Introduction to Pipe Relining Warranties

When it comes to maintaining and protecting your property’s plumbing infrastructure, having a product warranty for pipe relining work provides an extra level of assurance. Pipe relining is the process of restoring damaged pipes by coating them internally with epoxy resin to create a smooth, sealed flowpath.

This trenchless method is considerably less invasive, requiring no excavation of your property compared to traditional pipe replacement.

Reputable pipe relining companies usually provide warranties ranging from 5 to 10 years, underscoring the durability of epoxy resin linings when expertly installed. Such warranties enable Drummoyne residents and businesses to confidently undertake pipe relining, enjoying benefits akin to new piping without the upheaval caused by excavation.

We’ll explore common warranty terms, including what factors can void a claim, and why hiring an experienced, licenced plumber is key to maximising the lifespan of your relined pipes.

Typical Warranty Periods for Relined Pipes

When it comes to warranties for pipe relining, most established companies offer 5-10 year guarantees on materials and labour. This reflects the long-term durability of quality epoxy resin linings when properly installed in relining your pipes.

Certain enhanced warranty options can last over 25 years, with APR Supply providing a standout 50-year limited material warranty on their products when applied by a qualified technician.

The warranty length is influenced by variables such as:

  • The quality and formulation of epoxy resins used
  • The skill and experience of the relining technician
  • Compliance with surface preparation and application guidelines
  • Ongoing maintenance and proper use conditions

DIY epoxy linings may appear cost-effective but often lack any warranty, presenting risks compared to professional relining services. Hiring a licenced plumber like Drummoyne Plumbing ensures your relining job is done to the highest standard, maximising durability and warranty coverage.

25-50 Year Warranties

When it comes to the longevity of pipe relining, some of the most confidence-inspiring warranties extend 25, 30, or even 50 years. For example, APR Supply offers up to a 50 year limited material warranty when their products are applied by certified professionals.

These exceptional 25+ year warranties speak to the long lifespan of quality epoxy resin solutions we carry out for restoring pipes. It also shows the provider’s faith that their relining will endure decades of use if properly installed.

Qualifying for 25-50 year coverage necessitates rigorous adherence to surface preparation, application of suitable lining materials, ensuring adequate cure times, and a uniformly finished product. Proper maintenance and usage conditions also apply.

The availability of warranties lasting up to half a century highlights the remarkable durability of pipe relining. Even standard 10 year warranties far exceed the lifespan of other pipe repair methods in terms of longevity.

At Drummoyne Plumbing, our in-house expertise allows us to offer extended 15 year warranties on labour when we handle your complete pipe relining. We only use top-tier lining products installed to the highest standards, giving you peace of mind for years to come.

Factors Impacting Relined Pipe Warranties

When it comes to relined pipe warranties, there are several key factors that can influence the coverage period and validity of the guarantee:

Installation Environment

The environment where relined pipes are installed is crucial. Factors like soil acidity, groundwater levels, and potential chemical exposure can accelerate wear. Professional plumbers employ liner materials tailored to the local environmental conditions.

Pipe Usage and Flow

Most warranties specify limits on usage, pressures, and temperatures. Commercial kitchen drainage sees far more extreme flows than a residential sewer line. Your plumber will select an appropriate liner and advise on operating conditions to avoid voiding coverage.

Workmanship and Materials

Thorough training and professional execution of surface preparation, application, and curing are essential for a durable relined pipe. Failure to follow guidelines can greatly shorten warranty terms.

At Drummoyne Plumbing, our expert team handles your pipe relining to the highest standards using top-tier materials. This allows us to stand behind our work with extended 15 year labour warranties, giving you lasting peace of mind.

Proper Installation and Inspections

To maximise the longevity of your pipe relining and maintain the validity of warranties, proper installation by a licenced professional is crucial. This includes strict adherence to preparation, application, curing, and testing procedures for the epoxy materials used.

Ongoing inspections are crucial for early identification of issues, optimising the advantages of pipe warranties. At Drummoyne Plumbing, we offer CCTV drain inspections to keep track of your relined pipes’ condition and help catch problems before they become major headaches.

Drummoyne Plumbing’s expertise and timely service ensure local home and business owners benefit from expert pipe relining and our extended 15-year labour warranties, backed by quality work and superior epoxy products.

Following Recommended Maintenance

For efficient operation of relined pipes and to maintain valid warranties, adhering to the manufacturer’s maintenance recommendations is critical. This boils down to 3 key areas:

Appropriate Usage

Ensuring relined pipes are used under normal conditions is vital for warranty validity. Exceeding suggested pressure, temperature, chemical exposure or flow limits can accelerate wear. Adhering to operating guidelines preserves liner integrity.

Regular Inspections

Drummoyne Plumbing offers professional drain inspections to identify problems before they become costly headaches down the track while under warranty.

Addressing Problems Promptly

If problems do occur within the warranty period, have them assessed and repaired immediately by the original installer. Catching issues quickly improves outcomes and helps uphold warranty protections.

Adhering to the proper use, routine inspections, and timely repairs is paramount to ensuring relined pipes reach their full lifespan and warranty conditions are upheld.

Using Quality Materials

When it comes to pipe relining warranties, the quality of materials used is crucial. Top-tier epoxy resins, proper reinforcement fabrics, and compatible accessory components all impact durability and longevity.

Leading relining companies utilise premium-grade resins designed for safe potable water contact and robust chemical resistance. The resin’s mechanical properties, temperature tolerances, and expected service life are all factors.

Likewise, reinforcement fabrics are chosen based on the operating environment. Heavy-duty microfiber fleeces reinforce the epoxy barrier while allowing flexibility. This reduces strain over time.

Using inferior materials compromises integrity, shortening a lining’s lifespan and diminishing warranty protections. At Drummoyne Plumbing, our 15 year labour warranty reflects our meticulous standards and use of only the best trenchless pipe restoration products.

Understanding Warranty Terms

Understanding the terms and conditions is crucial when dealing with pipe relining warranties. Reputable companies should provide clear documentation covering drain pipe:

  • The duration of coverage (typically 5-10 years)
  • What aspects are covered (materials, labour, etc.)
  • Exclusions where the warranty would be voided
  • Usage, environmental, and maintenance conditions
  • Procedures for inspections and addressing warranty claims

Reviewing the details with our specialists guarantees you fully avail the benefits of warranty coverage and prevent invalidation. Exceeding temperature or pressure limits, using unapproved cleaners, or neglecting regular inspections could void the warranty.

Drummoyne Plumbing’s expert team is ready to answer queries about our comprehensive 15-year labour warranty. Our friendly team helps homeowners understand the relining process and associated warranty details for your drains, delivering complete peace of mind.

Coverage Duration and Conditions

When it comes to relined pipe warranties, the duration of coverage typically ranges from 5 to 50 years depending on the quality of materials and workmanship.

Most warranties cover defects in the epoxy liner material itself as well as any associated labour for repairs during the warranty period. This offers protection against issues such as cracks, leaks, or blockages that arise from liner failure, not external causes.

However, warranties usually specify certain usage conditions for your drain - such as flow rates, pressures, temperatures, and exposure to chemicals or abrasive flows - that must be adhered to. Exceeding these limits could void the warranty. Regular inspections are key to preventing complications such as tree root invasion and swiftly addressing any minor concerns.

Fully understanding your relined pipe warranty provides clear insight into your protections. Our team at Drummoyne Plumbing ensures you understand the details of your drain relining warranty for complete transparency.

Exclusions and Voiding the Warranty

While relined pipe warranties provide assurance, there are important exclusions and actions that can void coverage:

  • Pre-existing defects or damage not caused by the installed liner
  • Exceeding specified temperature, pressure, chemical exposure or abrasive flow limits
  • Failure to conduct maintenance inspections at required intervals
  • Damage from external factors like ground shifts, lightning strikes, etc.
  • Unapproved modifications, repairs, or attachments to relined pipes

Dependable plumbers like us provide thorough explanations of warranty particulars, fostering trust and clarity for future services. At Drummoyne Plumbing, we welcome any questions about our 15 year labour warranty and the specifics of what it covers.

The Warranty Claims Process

If issues arise with relined pipes within the warranty coverage period, there is a defined process for assessing the problem and determining next steps:

  1. Contact the original installer who turned up on time (ensuring timely service with Drummoyne Plumbing) for an initial inspection. Provide documentation like invoices or warranties.
  2. A skilled plumber utilises CCTV and diagnostic tests to pinpoint issues, assessing whether they stem from the epoxy liner’s faults.
  3. If the problem does stem from liner defects, the installer will advise on remedy options covered under warranty, such as repairs or relining affected sections.
  4. Any repairs carried out will aim to restore functionality and warranty protections, ensuring the site reflects a completed job, cleaned up and tidy afterwards. Terms may stipulate use of original installer.
  5. If the issue is not deemed a warrantied defect, still address promptly as leaving damage unchecked voids most warranties over time.

Following warranty claim protocols and maintaining all installation records are essential for a streamlined claims experience. Drummoyne Plumbing’s 15 year labour warranty makes potential repairs smooth and hassle-free for local properties.

Information Needed for Claims

When submitting a warranty claim for relined pipes, having the following information on hand helps speed up processing and resolution:

  • A copy of the original invoice or warranty documentation
  • Details of the company and technicians who performed the relining
  • The exact date the relining work was completed
  • Video footage and photos showing the current state of damage
  • Written description of problems noted, including leaks, cracks, blockages etc.
  • Notes on when issues first started occurring
  • Overview of operating conditions - pressures, temperatures, exposure to chemicals
  • Documentation of any recent inspections or maintenance performed

Providing this information enables our technicians to promptly assess warranty claims, ascertain the damage root cause, and undertake repairs as warranted.

Evidence Required

When submitting a warranty claim for relined pipes, providing clear evidence of damage or defects is crucial. Photos, videos, and CCTV footage showing cracks, leaks, blockages or other issues can validate warranty coverage when liner failures are at fault.

Thorough visual documentation makes it easier to identify covered manufacturer defects as the cause rather than pre-existing conditions or external factors. Slow-motion footage can uncover minor faults that might be overlooked.

In addition, having a detailed installation report with before and after images from the original job provides a baseline for assessing connector points, transitions, or high wear areas where new damage emerges over time.

At Drummoyne Plumbing, we retain thorough documentation of all our professional relining projects. This allows for seamless warranty claims supported by evidence pinpointing the root cause of any damage to your restored pipes.


Warranties are fundamental in providing peace of mind to individuals choosing trenchless pipe relining solutions. with reputable providers like Drummoyne Plumbing, Sydney residents can secure 10-15 year coverage against defects in materials and labour for your pipes.

Although warranty terms differ, typical durations of 10 to 20 years demonstrate the superior longevity of pipe relining over conventional pipe repairs. Compliance with operating conditions along with proper maintenance preserves protections. In the unlikely event issues emerge from installation flaws or epoxy failures, clearly documenting the problem was very instrumental in accelerating claim resolutions.
