Disclosed is an expansion tank having an internal cavity separated by a flexible diaphragm to form an upper pressurized gas portion and a lower pressurized fluid portion, and an indicator positioned at an upper part of the expansion tank in communication with the contents of the upper pressurized gas portion. The indicator is configured so as to display a first color if the operating conditions are normal in the pressurized gas portion, and a second color if the amount of moisture detected in the pressurized gas portion greater than or equal to a predetermined amount. Further disclosed is a method for detecting whether there is an excessive amount of moisture in a pressurized gas portion of an expansion tank by allowing pressurized gas from the pressurized gas portion to come into contact with the indicator, and viewing the color displayed by the indicator. As such, the tank can be simply visually inspected to determine whether there is a potential failure in the tank.

Disclosed is a device for causing turbulent flow in a tank assembly that has an internal fluid cell and a fitting for allowing fluid to enter and exit the fluid cell from the exterior of the tank assembly. The device includes a main body portion and first and second retaining arms. The first and second retaining arms extend from the main body portion of the device and are adapted and configured for supporting the device substantially within the fitting of the tank assembly. A plurality of curved vane elements extend from the main body portion which cause turbulent flow in the fluid cell of the tank assembly by redirecting fluid entering the tank assembly axially through the fitting in a non-axial direction into the fluid cell.
