The nagging worry of eliminating system pressure has all but been eliminated. Falcon Stainless E.T. potable water expansion tanks are designed to maintain safe pressure in domestic water systems that utilize a backflow preventer or check valve.
E.T tanks feature a 100 percent butyl diaphragm and plastic liner to separate the system water from the tanks’ air precharge. The system connection has a stainless steel sleeve to prevent corrosion, making it even more reliable. And, the tanks are finished with appliance-quality paint, which helps prevent external corrosion. In addition, every tank is comprehensively tested and backed by Falcon’s five-year limited warranty.
