Since we manufacture our own tanks, we remain in complete control of the process. Pods are rotomolded, so there are no seams, joints, or glues required. Each pod is formed as a whole. In our factory, we pressure test each pod to 20 Pa and try to make them ‘pop’; at a far greater rate than there is likely to be any air in the product.
Then we measure each to make sure the thickness is at least 5mm. Each pod has its own serial number, which can be tracked throughout the entire manufacturing process. On installation, pods are pressure tested again once they reach site. When steel is attached to the pods, they are pressure tested again, and then again once concrete is poured (only in Auckland). Afterwards, the installer will issue a PS3.
Multiple tests are carried out during production and installation to ensure that the product is fit for its intended purpose. All pressure tests are recorded. You don’t have to worry about slow leaks, because you will hear them! The sound is so loud it’s been likened to a freight train.
