WATER PURIFIER HAVING BYPASS PIPE FOR SWITCHING WATER CHANNEL

PROBLEM TO BE SOLVED: To provide a water purifier having a bypass pipe for switching a water channel, capable of allowing tap water to flow toward the bypass pipe to perform work for replacing a cartridge or a main body using a three-way valve and the bypass pipe and capable of reducing the number of the three-way valves minimally to reduce the attaching space of the three-way valve and the bypass pipe. SOLUTION: This water purifier is equipped with a water purifier main body 1 for purifying tap water, left and right guide pipes 3 and 5 separately connected to the water inlet and outlet of the water purifier main body 1 on one end sides thereof, the left and right three-way valves 6 and 6 respectively connected to the other end sides of the left and right guide pipes 3 and 5, and the bypass pipe 9 for allowing the left and right three-way valves 6 and 6 to communicate with each other to form the side channel of the water purifier main body 1.
