Introduction to Pipe Relining

Pipe relining efficiently repairs damaged pipes without the need for excavation.

It involves inserting a resin-saturated liner into the existing plumbing pipe and curing it to form a new, jointless pipe within the old one, enhancing Sydney water systems. This method restores water pressure and flow, effectively preventing leaks and damage from cracks, corrosion, or root intrusion.

Relining can repair various water systems, like water mains, sewer pipes, and stormwater drains. Even your piping, including those under buildings and slabs, can often be accessed at an entry or access point for relining through cleanouts.

The non-destructive nature of our advanced relining technology makes it well-suited for a wide range of applications, all safely carried out. A common concern is whether relining affects the safety and quality of drinking water. This article explores that issue in depth, providing homeowners with the information they need to evaluate pipe relining solutions.

How Pipe Relining Works

The relining procedure for lead pipe systems comprises several key stages:

  1. Initial drain camera inspection. A camera is inserted into your damaged pipes to assess their condition and determine if relining is the suitable repair approach.
  2. Pipe work cleaning. The existing pipe is thoroughly cleaned to remove debris, rust and scale.
  3. During the resin wet-out stage, the liner is saturated with a thermosetting epoxy resin.
  4. During the pipe relining process, the resin-saturated liner is inverted or pulled inside the old pipe.
  5. Curing. The liner material cures under heat or UV light, bonding to the host pipe.

Once cured, the epoxy resin forms a tight seal within the host pipe, transforming it into smooth, jointless, corrosion-resistant drainage pipes. This restores hydraulic capacity, stops leaks, and prevents further deterioration.

Sewer line relining can be used in repair on various materials including concrete, clay, PVC, steel, and even cast iron pipes. PET felt liners are often chosen for hot and drinking water, while vinyl ester and polyester suit sewer applications.

Unlike traditional pipe replacement, relining provides a trenchless repair that keeps surrounding infrastructure intact. The relining procedure is executed swiftly, usually in a matter of hours, which is significantly less than the days or weeks required for excavation. This results in major cost and disruption savings.

Relined systems often exceed a 50-year design lifespan, even for sewer pipes. They are engineered to withstand pressure fluctuations, ground movements, water leaks, abrasion, chemical exposure and other stresses. Relining results in a code-compliant upgrade equivalent to installing new pipes, minus the mess and cost of excavation.

Pipe Materials Used in Relining

Pipe relining utilises specially engineered liner materials that are safe, durable and reliable for your plumbing system, ensuring clean drinking water after installation. The most common liner types used are:

PET Liners

Polyethylene terephthalate (PET) felt liners are commonly used for relining water pipe that carry your water. PET is a safe, inert plastic that meets health standards for direct contact with drinking water. It provides a smooth, non-porous, corrosion-proof flow surface that will not affect water quality or leach contaminants.

PET liners are flexible, allowing installation around bends. They can also restore flow capacity as PET has a very low friction coefficient. Studies suggest PET pipe liners can be more durable than other materials, with a typical lifespan of 50-100 years.

Epoxy Resin

An epoxy resin saturates the PET liner, providing a protective coating. Epoxy creates a durable chemical and abrasion-resistant barrier. It also bonds the liner to the existing pipe for structural strength.

Modern epoxy resins used in potable water relining are 100% solids, containing no volatile organic compounds (VOCs) that could taint drinking water. They are certified to NSF/ANSI Standard 61 for materials contacting drinking water.

Overall, the benefits pipe relining provides with an inert PET liner and protective epoxy coatings include a safe, long-lasting surface for drinking water contact after relining.

Pipe Relining and Drinking Water Safety Standards

In most countries, materials that contact potable water must comply with NSF/ANSI Standard 61 or similar regulations.

These standards ensure that no substances are leaching into water sources from plumbing materials, adhering to maximum contaminant levels.

Quality composite resin systems used in pipe relining are formulated to pass these strict drinking water standards. For example, Nuflow’s Nu Line EPX epoxy compound is NSF/ANSI Standard 61 certified for potable water contact in drain pipe applications.

Studies by water authorities have verified the long-term safety of properly installed composite liner systems. With quality controls and proper curing, Relining your pipes incorporates a dependable barrier protecting the water passing through your water meter.

Overall, certified resin products combined with expert installation ensures pipe relining meets the highest standards for safe drinking water contact.

Testing Water Safety Before and After Relining

Comparing pipe relining vs traditional methods, it’s crucial to test drinking water quality both before and after pipe relining to ensure the procedure doesn?ss, chlorine, turbidity and contaminants.

During relining, samples in contact with the resin system are tested to ensure compliance with strict health standards. We adhere to best practice protocols during installation and curing to prevent any risk of leaching or tainting. Throughout the process, your drinking water remains completely isolated from the liner.
