Used Iplex Pro-fit or Buteline? WaterLink is your next step.
If you've previously worked with Iplex Pro-fit or Buteline polybutylene systems in Australia, you're in the right place. Those systems are no longer available locally, and LEAP is now the only Australian distributor of PB-1 plumbing systems. Our PB-1 pipes and fittings are made with the same trusted PB-1 polymer from LydonBassell.
Leap WaterLink PB Crimp offers full compatibility with legacy installs, updated fittings, and a 25-year warranty, which are all supported by national distribution and compliant with AS/NZS 2642.
FAQs
-
PB-1 is flexible, lightweight, and corrosion-free, making it easier and faster to install than copper or PEX. It’s quiet in operation, resists freezing, and delivers proven long-term performance with fewer call-backs.
-
Yes. The pipes are made from the same high-quality PB-1 resin. The fittings differ slightly: Hep2O fittings use Grab-Wedge technology; WaterLink PB Push Fit fittings use Grab-Ring technology. Both are effective, interchangeble and compliant with AS/NZS 2642. This applies to other pipe brands that are AS/NZS 2642 compliant.
-
LEAP replaced Hep2O with WaterLink in Australia to simplify product identification.
The Hep2O tradename belongs to Wavin who phased out the Hep2O grab-wedge push-fit fittings.
WaterLink push-fit fittings use Grab-Ring technology.
WaterLink crimp fittings are manufactured using LF/DR brass with copper crimp rings.
-
Available through major plumbing merchants across Australia. Contact us to find your nearest stockist.
-
Yes. WaterLink pipes are actively stocked and sold nationally and backed by a 25-year warranty.
-
LEAP has distributed Hep2O in Australasia since 2002, with WaterLink introduced under its new name in 2019.
-
No. The Iplex class action involved a different PB resin from another supplier. LEAP products are made with LyondellBasell PB-1—a globally trusted material, compliant with AS/NZS 2642.
-
No. WaterLink and Hep2O systems are not involved in any legal or class action claims. They have a strong track record and are supported with compliance, warranty, and technical guidance.
-
PB-1 piping systems have demonstrated exceptional long-life performance in demanding applications and are recognised for their low environmental impact. They offer efficient and reliable assembly, pipe flexibility, on-site handling, and best-in- class energy efficiency. Reference: PBSA
