18 l Lead-Free Potable Water Thermal Expansion Tank Value:each 0 Charger Included Charger NotThe 4. 8 gallon XT 18 Thermal Expansion Tank is utilized on potable water lines between the backflow preventer or pressure reducing valve and the water heater for protection against water thermal expansion in residential applications.
