Abstract: A water circulation system for hospitals and other facilities with large water circulating systems. A pressure and/or flow sensitive valve directs low pressure, high temperature water in the outlet head to a return pipe, while directing high pressure water to water outlet openings. The system allows a constant flow of heated water above 55° C. past water outlet heads even when the water system is not in use, thus avoiding static water in pipe lines and the growth of microorganisms.
Abstract: A water circulating system for reducing the growth and accumulation of micro-organisms for hospitals and other facilities with large water circulating systems. The system allows a constant flow of heated water above 55° C. past water outlet heads even when the water outlet head is not in use, thus avoiding static water in the pipe lines and the growth or accumulation of micro-organisms.
