A heat trap assembly includes a housing adapted for interconnection between a hot water tank and a water line with the housing including an interior flow chamber. A one-way valve is disposed within the chamber for enabling unrestricted water flow only in one direction through the chamber. The valve includes a valve seat fixed within a chamber along one direction and movable in an opposite direction along with a movable sealing member. A spring is provided for urging the sealing member against the valve seat to prevent flow though the chamber in the opposite direction. Water flow in the one direction compresses the spring and dislodges the sealing member from the valve seat. A pressure relief disk is provided and disposed between the valve seat and the end of the chamber. The pressure relief disk compresses under a selected water pressure exerted in the opposite direction for enabling flow in the opposite direction at pressures greater than a selected water pressure within a hot water tank.
