EVERFLOW® HYDRONIC EXPANSION TANK

  • Tanks absorb the expansion of hot water, keeping system pressures below relief valve settings and avoiding added stress to system components.
  • Protects safety valves from failing, avoids valve stem and ball seal leaks, prevents wasted BTUs, and vastly extends water heater life.
  • Available in 2.1 & 4.7 Gallon
EVERFLOW® THERMAL EXPANSION TANK
  • ETX Series thermal expansion tanks are diaphragm type pre-charged tanks designed to protect residential potable hot water systems.
  • Tank is designed for installation between the backflow preventer and the water heater to accept expanded hot water, keeping system pressure below relief valve settings and avoiding added stress to system components.
  • Water is contained in a food grade polypropylene reservoir with rubber diaphragm separating the expanded water from the air cushion.
  • Protects safety valves from failing, avoids valve stem and ball seal leaks, prevents wasted BTUs, and vastly extends water heater life.
