Abstract: The herein described apparatus is a novel expansion tank and method for use with a water system. The housing of the expansion tank contains a spring biased piston. When the water pressure of the system is sufficient to overcome the spring's resistance, the piston will be compressed against the spring allowing water to flow into the expansion chamber. As the water pressure of the system decreases, the spring will bias the piston towards its rest position and force water from the expansion tank. By using a piston in place of the prior art rubber diaphragm a more robust mechanism to contain water resulting from thermal expansion is provided.
