Studies show that pipe relining using epoxy barrier coatings is generally considered a safe method for rehabilitating drinking water pipes when using approved, non-toxic materials that meet health standards. However, proper safety precautions should still be taken during the relining process.
Pipe relining is a trenchless technology for repairing pipes often damaged by obstructions such as tree roots, without the need for excavation. It involves applying an epoxy coating within the damaged pipe to form a new, stable 'pipe within a pipe’ structure.
The key steps in the pipe relining process are:
Trenchless pipe relining offers an efficient, non-invasive alternative, minimising disturbance to your property and plumbing system.
Pipe relining uses specially formulated composite resin materials for internal pipe safety that are drinking water safe and meet health standards. The key properties that make these materials suitable for potable water lines include:
Solid epoxy, often used in relining, cures without leaving toxic residue. Antimicrobial technology within some linings deters bacterial growth, while fibreglass provides added structural strength. These modern materials are designed to maintain water quality and safety.
Epoxy resin is one of the most widely used and trusted materials for pipe relining applications involving drinking water. It offers unparalleled durability, safety, and resistance to corrosion and chemicals.
Epoxy resin linings are certified to NSF/ANSI Standard 61, ensuring safety for potable water systems even with copper pipe. This guarantees that the water system remains uncontaminated as the cured epoxy won’t leach any toxic substances into the water supply. Epoxy also provides an ultra-smooth finish that prevents build-up and optimises water flow.
Epoxy used in relining is void of volatile compounds, thus not leaving any toxic residues post-curing. It forms a durable, seamless barrier against corrosion, significantly extending the lifespan of pipes, often by over 50 years.
Pipe relining with epoxy resin offers rapid installation and absence of excavation, streamlining the repair process, saving costs, and using time efficiently compared to traditional replacement. It’s suitable for both pressurised and non-pressurised drinking water pipes across residential and municipal settings.
Pipe relining in Australia must adhere to strict standards and regulations to ensure safety, quality and reliability, especially when used for drinking water supply.
The critical standards adopted are as follows:
Accredited contractors follow best practice guidelines on cleaning, resin impregnation, and curing, in line with disease control standards, to deliver optimal results.
Certified trenchless relining specialists, dedicated to upholding your home’s plumbing integrity, possess formal qualifications and are audited regularly to confirm their expertise. They conduct relining in compliance with all relevant Australian standards and regulations.
Certified specialists ensure that repairs meet Australian standards for materials, workmanship, and safety, contributing to safe, long-lasting results.
The Australian Drinking Water Guidelines set by the National Health and Medical Research Council govern drinking water safety, outlining health-based targets to protect public health.
Key requirements in the Australian Drinking Water Guidelines relevant to pipe relining include:
To meet these guidelines, accredited relining contractors follow strict protocols on cleaning, resin impregnation, curing and testing. Only WaterMark certified products are used and samples are collected post-relining to validate drinking water safety.
So while any pipe repairs or modifications can affect water quality, when one does pipe relining with certified, drinking water-safe epoxies, compliance with Australian health standards is ensured. This guarantees the ongoing delivery of safe, high quality drinking water to properties.
It’s crucial to choose a qualified local plumber who is certified in pipe relining to ensure repairs are performed properly and safely, with technicians adept in trenchless pipe repair and pipe lining methods.
Certified trenchless relining specialists, trusted for repeat service, must have qualifications such as a Certificate III in Trenchless Technology and be licenced plumbers, guaranteeing adherence to industry best practices and standards for quality, compliant results.
At Blacktown Plumbing, our qualified technicians, well-versed in pipe inspections, cleaning and epoxy relining, tackle tasks efficiently. Continuous education ensures our team’s proficiency in the latest relining techniques and materials, enabling us to perform professional, safe repairs.
When selecting any pipe relining company, check their credentials, licences, insurance coverage and guarantees for pipes without. Reputable providers will be transparent about their capabilities and processes when you need them. Though relining is non-invasive, selecting technicians who can help gain proper qualifications ensures the health and safety of your pipe infrastructure.
The benefits pipe relining offers are remarkably vast, particularly in the context of ageing cast iron systems, in safeguarding and improving drinking water quality and safety.
The seamless pipe coating with epoxy preserves pipe integrity, preventing corrosion and build-up of sediment and bacteria within leaking pipes. This removes a major source of water contamination and debris that can enter water pipes. By restoring pipe integrity, relining enables optimal water flow and water pressure as well.
Certified potable water-safe epoxies along with proper curing methods make sure the lining materials themselves don’t leach any toxic chemicals either. This maintains water quality even with aged pipes that have had epoxy lining inserted into them.
As a trenchless technology, relining ensures there no excavation that could expose pipes to contaminants. The pipe fully remains enclosed preserving sterility, ensuring there’s no disruption to surrounding soil and infrastructure that could release pollutants near your water line.
Properly relined pipes are estimated to function reliably for more than 50 years, maintaining water safety and quality, with continual testing affirming adherence to health standards.
Relining serves as a long-term solution that enhances drinking water quality for years to come. Although materials and methods may differ, certifications ensure that safety is paramount, for all pipe types including copper.
There are minimal health risks associated with properly relined drinking water pipes. The NSF/ANSI 61 certified epoxy materials are rigorously tested to validate they won’t leach any hazardous chemicals post-curing that could pose a health concern.
In fact, relining removes corrosion and contamination sources to improve water quality. The materials are more inert than degrading pipe substrates. Studies by water authorities have verified relined pipes uphold key health standards for over 50 years.
Comparatively, traditional pipe repairs on a broken pipe frequently use glues, solders, and sealants, some of which have components that may leach into the water supply. They also require digging, which can introduce contaminants. Relining avoids this without compromising integrity or quality.
Certified contractors mitigate risks by adhering to best practices for preparation, installation, and post-relining testing, underpinning all work with precision. Measures such as CCTV inspections and NATA-approved water sampling assure relining as a safe, long-term solution.
Trenchless relining offers considerable advantages over traditional 'dig and replace’ pipe repair methods. As a no-dig technology, it ensures there is no digging up or disruption to landscaping, concrete, or infrastructure. There’s no contamination risk from exposing pipes or digging near the waterline network.
Relining extends the life of water mains, sewer lines, and stormwater systems quickly, sustainably, and cost-effectively. Epoxy barrier linings provide over 50 years of reliable service at a reasonable cost.
Property owners benefit from the convenience, value, and performance of relining:
