[0007] Furthermore, the stainless steel casing is a stainless steel casing with a bellows.

[0008] Furthermore, the stainless steel casing has a turning point, and a bellows is provided at the turning point for turning the casing, which makes the connection of the casing more convenient. The completed casing has continuity and can discharge leaking water to an outdoor finished leak detection well.

[0009] Furthermore, the pipe support is composed of stainless steel round steel with a size larger than the inner pipe and support legs. The diameter of the support legs is smaller than the diameter of the inner pipe. The pipe can be fastened by pushing it in the installation direction. Different contact surfaces are set according to the different materials of the inner pipe. The steel pipe uses a stainless steel contact surface, and the plastic pipe uses a plastic protective sleeve contact surface.

[0010] Furthermore, water leakage detectors are installed in sections in the pipeline or in leak detection wells according to needs.
