These potable water expansion tanks feature a 100% butyl diaphragm combined with a copolymer lower water chamber for maximum water and air separation. There is no better way to separate the system water from the tank's air precharge. The system connection has a stainless steel elbow to prevent corrosion, and the tanks are finished with appliance-quality paint to help prevent external corrosion. Not to mention, every WHV tank is comprehensively tested and backed by Flexcon's five-year limited warranty.
