ABSTRACT:
A hot water system in which a damped, gravity operated, check valve is interposed between the hot water heater and the hot water delivery pipe network. The valve opens when a tap is opened allowing hot water to pass into the pipes and to the tap. The valve is prevented from closing abruptly when the tap is closed by a close fitting cylinder which surrounds the valve piston and restricts fluid flow necessary for valve closure.
