PROBLEM TO BE SOLVED: To switch the water discharge in three stages, i.e., discharge of generated water such as purified water or ionized water which is generated in a water treatment system, straight discharge of raw water, and shower discharge of raw water by one lever operation by providing a valve body comprising a valve operation body and a valve switching body, and fitting a spool valve in the valve switching body. SOLUTION: An approximately cup-shaped valve operation body 30 and an approximately hollow and columnar valve switching body 40 are separately formed, and both bodies 30, 40 are coupled with each other by a connection ring 21 to constitute a valve body 20, and the whole system is surrounded by a case 12. A branch port 32 capable of connecting hoses to feed raw water to a water treatment system from the valve switching body 40 is provided on a back surface part of the valve operation body 30, a relief valve to flow out a part of raw water flowing through a water flow port 41 outside when the water pressure reaches or exceeds a specified value is provided, and a lever 34 turnable within a range of a specified angular range is provided on a right side surface part of the valve operation body 30. A spool valve 80 is provided on an inner circumferential surface of the valve body 20, and the valve 80 is connected to the lever 34 through a guide shaft 83 provided thereon.
