Placing a PicoPica10 in a waterway will cause the water wheel to rotate while the water is flowing. Therefore, the “lower bearing” and “generator (bearing inside the generator)”, which are the components that support the rotation, are consumable parts that continue to rotate, so maintenance (replacement) is required. Lower bearings and generators can be purchased from our inquiry form.
