Thermal expansion definition

Thermal expansion means the pressure increase due to a rise in water temperature that occurs in water piping systems when such systems become "closed" by the installation of a backflow prevention assembly or other means, and will not allow for expansion beyond that point of installation.
Thermal expansion means the pressure created by the expansion of heated water.
Thermal expansion means volumetric increase of water due to heating resulting in increased pressure in a closed system.
