ABSTRACT:
A water faucet includes a lower upright pipe integrally formed by a working process, and an upper upright pipe mounted on an upper portion of the lower upright pipe and formed by cutting a hollow pipe. Thus, the upper upright pipe is formed directly by cutting a hollow pipe, so that the upper upright pipe is made easily and rapidly, thereby decreasing the costs of fabrication, shortening the manufacturing time, simplifying the working process, and enhancing the working efficiency.
