Using this trainer the function of a normal expansion vessel is examined and a pressure-volume characteristic recorded. The expansion vessel is filled with water from a supply tank.
The pressure is generated using a small compressor and adjusted using a pressure regulating valve. The amount of water taken up by the expansion vessel is read on a scale on the supply tank.
