FIELD OF THE INVENTION

The present invention relates to a corporation stop, and more particularly relates to a fluid diverting device.

BACKGROUND OF THE INVENTION

A corporation stop is a kind of water dividing unit, which is usually installed in a branch position between the main water pipe and the branch water pipe to allow tap water, supplied by a tap water corporation, to distribute to an end-user. One end of the corporation stop is connected to the water supplying pipe, and the other end of the corporation stop is connected to the water pipe of the end-user such that the tap water can be diverted to end-users.

The corporation stop is usually mounted on a saddle to attach to the water pipe. However, because a conventional corporation stop is with its mounting structure poor to be fixed between the corporation stop and the saddle, it causes drawbacks such as sewage and impurities permeating from the environment through the poor mounting structure between the conventional corporation stop and the saddle. It thus pollutes the tap water. Therefore, an improvement to the conventional corporation stop is required.
