Thermal Expansion Tank

(Mandatory for any city that requires a check valve or has a closed water system- including Carrollton and Addison)
Thermal expansion tanks are plumbed to the water heater. They are designed to hold the extra volume of water that can be produced when cold water is heated in the tank. Certain cities in the Dallas Metro area require a thermal expansion tank with the water heater. A thermal expansion tank has a sealed-in compressible air cushion, which will compress as thermal expansion occurs in the water heater. The thermal expansion tank provides a space to hold and store the additional water volume.
