A circulation type water purifier prevents production of bacteria and microbes by periodically circulating water and also increases pump life and reduces pump costs by varying circulation times depending on an amount of water used. The purifier includes a filter 100; a purified water storage tank 200; a cold/hot water supply tank 300 having respective outlets for hot and cold water and drain outlets; a sterilizer 900; and a pump 400. Under control of a microcomputer, the pump periodically circulates water through various circulation piping. |
