This is a method and means for maintaining a constant supply of a fluid with specific characteristics within a fluid supply conduit from a supply source of the fluid with specific characteristics at a point of service of the fluid with specific characteristics in which a first open end of a recirculation conduit is located within the fluid with specific characteristics supply conduit adjacent the point of service. A second end of the recirculation conduit is connected to pump means in such manner that a portion of the fluid with specific characteristics within the fluid with specific characteristics supply conduit adjacent the point of service is constantly circulated back. In an alternate embodiment a similar recirculation conduit is utilized in a manner to prevent freezing of conduits in a total fluid supply line which includes portions in relatively warm areas and in areas subject to freezing.
