Product Details

WATER EXPANSION TANK: With a 2.1 gallon volume, the Watts Potable Water Expansion Tank is designed for use in commercial and residential closed loop hydronic heating system piping to control the thermal expansion of hot water and maintain system pressure below the relief setting of the relief valve.
DURABLE CONSTRUCTION: This water tank is constructed from high-quality carbon steel with an epoxy finish, ensuring long-lasting performance. It is also equipped with a durable expansion membrane that minimizes the loss of the air charge.
VERSATILE MOUNTING: This potable water expansion tank is designed for easy installation, mounting directly to the supply piping whether standing on top of a pipe or hanging from one. Tank features a 3/4-inch male connection and a stainless steel inlet.
HIGH PRESSURE CAPACITY: This pre-pressurized steel tank is built to withstand the demands of hydronic heating systems. It works in tandem with hot water heaters to absorb increased water volume, preventing system overpressure and ensuring the longevity and efficiency of the heating system.
