Amtrol invented the pre-pressurized water storage tank over 50 years ago and they are still considered the standard of the industry. These tanks feature a polypropylene liner and butyl diaphragm to prevent water from making contact with the metal tank for cleaner, fresher, better tasting water. All Amtrol RO tanks are manufactured in the USA at our ISO 9001:2008 registered facilities.
