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.

  • 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. Both are effective and compliant with AS/NZS 2642.

  • The product hasn’t changed, just the branding. LEAP renamed Hep2O to WaterLink in Australia to simplify product identification and reinforce our ownership of the PB system range. Same PB-1 pipe. Same fittings. Same performance.

  • 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
