A three-way valve includes a body, a chamber formed in the body, a valve positioned in the chamber and having a shaft formed to extend upward from the valve and connected with a lateral grip at an outside of the body. The grip is rotated to open and close easily the three-way valve. The valve is placed in advance in a mold in which the body is to be formed, and positioned in the chamber after the body is formed by injecting process. O-shaped rings used in conventional three-way valves are not necessary.
