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.

-
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.
