Abstract Today in residential buildings, cold & hot water supply system is composed of boiler, pipe, and faucet and so on. That is the equipment function with one system. Specially, high-rise residential buildings bring on discomfortable use and unexpected conditions on account of faucet outlet pressure rise and the difference of water supply pressure between top and bottom floor. Cold & hot water manifold system introduces positively for supplying cold & hot water more stably from residential buildings. But, the plan data is insufficient for manifold system. If water pressure is not appropriate, it loses the function of water supply system. The researches became accomplished which solve the problems about difference of water pressure between top and bottom floor and unbalance of flow rates with introduction of many water supply system and vertical zoning methods. But, the researches leave something to be desired about decrease of water pressure and flow rate or change of hot water supply because of simultaneous waste flow rate in a household. Thus, the purpose of this study is to present flow balancing plan data for performance improvement of cold & hot water manifold system through evaluating performance of alternative plans with mock-up test.
