Prior to transporting or moving any Berkey system, the Black Berkey Purification Elements must first be removed. Failure to remove the elements from the system can result in broken stems. Place the elements in secure and water-tight packaging. The top and bottom of the stainless steel systems nest within each other for easy transport (remove spigot from the lower chamber). Please note: Failure to remove the elements from the system can result in broken stems. This is not covered under the manufacturer’s warranty.
