Abstract
A water purifying system having a bypass path supplies raw water to an outlet when a filter assembly is separated from a valve assembly. The water purifying system includes a valve assembly having a valve cover with an inlet and an outlet, and a head member moved up and down within the valve cover to form an inflow path and an outflow path, and a filter assembly removably connected to the valve assembly and mounted with a filter. When the filter assembly is connected to the valve assembly through a linear motion, the filter assembly advances the head member so that a fluid flown in through the inlet is guided to the outlet passing through the filter. When the filter assembly is separated from the valve assembly, the head member is retreated so that the fluid flown through the inlet is guided to the outlet bypassing the filter.
