The Vecto is made from TPU, which is a porous material that can degrade over time depending on exposure to high or low temperatures, UV rays, and abrasion. All the parts in the Vecto are made from TPU and are welded together, so no bonding (glue) is needed. Because of this, manufacturing faults in the Vecto show themselves in the first use or couple of uses, not gradually over time. Vectos are covered by a 1 year warranty.
Pinholes can develop from a host of reasons, including exposure to UV rays, colder temperatures, abrasion, etc. They are not covered by warranty unless they occur new from the box. The Vecto is made from porous TPU that balances weight and durability, and is reliable and repairable in many conditions while staying light and easy to use. While pinholes are annoying, they are not catastrophic and can usually be fixed with a small (round) patch of Tear-Aid Type A or a drop of superglue on the outside of the pinhole.
Sliders are made of standard stiff plastic (ABS) and breakage can occur for a host of reasons (increase in weight and/or torque, hanging at an angle). A broken loop on a slider is not covered by warranty as breakage can happen from a host of reasons. The loop in the slider is designed to be used to hang the Vecto for a gravity feed and can hold up to 20 lbs. of weight if hung with a carabiner or GearTie that hangs vertically, and isn't pushing or pulling the loop. Any increased weight or twisting can cause breaking.
Additional parts for your Vecto can be found here (scroll down for Replacement Sliders and Caps).
Discoloring of TPU products can occur as we do not use BPA, BPF or BPS in our TPU, which are the main chemicals used to keep plastics clear. This means that with the right combination of UV exposure and water chemicals our products can turn yellow, green or even orange. If the TPU changes color it is safe to use and not faulty.
Temperature: Your Vecto is reactive to temperature change: in high temperatures, it becomes softer and in low temperatures, it is stiffer. The Vecto is limited to 50 degrees C/120 degrees F. If you use water higher than this, it will damage the welds and ruin the Vecto and will void any warranty.
