Do I need to cover the pond liner, and how does this affect the warranty?

The Premium RPE Liner includes a 20-year warranty, even when left uncovered and exposed to direct sunlight, because of its high UV resistance. However, it is still recommended to cover the liner to protect it from long-term exposure to sunlight. This can help to extend the life of the liner and prevent any potential damage or degradation over time. The Classic RPE Liners do require covering at all times in order for the warranty to remain valid for 20 years. Additionally, covering the liner can also help to make the pond look more natural and aesthetically pleasing. Some common options for covering the liner include using rocks, soil, or other fill materials to create a more natural-looking shoreline.
