What is WaterMark accreditation and why is it important?
The WaterMark Certification Scheme has regulated the use of plumbing and drainage products in Australia since 1988, with only authorised products deemed legally fit for use in plumbing and drainage installations. Until recently, relining products sat outside of the WaterMark scheme, with no accreditation required or regulating authority managing the materials or the manner in which they are utilised in Australia.
As of November 2018, it has been a legal requirement for pipe reliners to use WaterMark approved products, installed as per the Plumbing Standard of Australia AS3500. Products and techniques that sit outside of these guidelines are now deemed unsuitable for use within Australia.
At Sydney Relining, the quality of the products and systems we utilise has been of high priority throughout our 30 years looking after Sydney’s plumbing, always ensuring they are of the highest standard and deliver great value for money for our customers. It, therefore, goes without saying that Sydney Relining happily guarantees that all of our products and systems are approved within the WaterMark Certification Scheme.
With many systems and products available, developed, and distributed by brands across the globe (check out – Key things to consider when choosing your product), we’re only too glad that our niche industry is being more strictly regulated moving forwards.
However, as the consumer, you must be aware that the scheme is enforced by the state and territory plumbing administrations at the point of installation, not sale. Therefore products without WaterMark certification can be purchased openly, without any penalty to the supplier. This makes it imperative that you ask your plumber or reliner to ensure the products they’re using are certified.
You can find out more about what products and specifications require certification in the WaterMark Schedule of Specifications and if you have any questions or queries, give one of our relining experts a call anytime.

Pipe Relining
How does pipe relining work?
Think of relining as feeding an inner tube into the current pipe, then hardening and sealing that tube until it’s stronger than any clay, terracotta, or plastic pipe.
Rather than excavating and replacing the damaged pipe, causing mess and disruption to your property (and your bank balance) – we reline from the surface.
Using the best available Watermark accredited tech and using ultra-strong, impenetrable EPOXY resin, we cause a minimal fuss, often maintaining services and completing most projects within a single day.
The process
- Investigate – Using CC.TV technology, we investigate the problems and provide you with an itemised quote for the work that needs to be done, taking the time to explain where the budget is being spent and why arming you with the information you need.
- Prepare – We take time to prepare above and below ground to ensure we cause minimal disturbance by establishing safe work zones and diverting any plumbing systems where possible, avoiding service disruptions.
- Reline – Only then do we cure and install our impenetrable EPOXY resin using state-of-the-art relining techniques that allow us to accurately pinpoint the damaged section of the pipe, drain or sewer and navigate any bends or junctions.
We create and install a guaranteed 50-year solution with our superior relining products & materials coming with a life expectancy of 50 years and up.
