[0006] However, when water is injected into the drain container using an externally provided water injection pipe, the water injection pipe is placed behind the ceiling after the installation work is completed, and water cannot be easily injected.

[0007] Therefore, the water injection into the drain container must be performed from the outside while the ceiling is always opened, that is, the decorative panel is not attached. For this reason, drainage can not be checked after the installation work is completed after the ceiling is closed and the decorative panels are assembled, so the installation contractor must perform it during the installation work. The operation of the drain pump could not be checked. Also, if the piping work of the external drainage pipe is delayed, the drainage drainage cannot be confirmed, so that the ceiling cannot be closed, and the installation work cannot be further advanced.

The present invention has been made in view of such a point, and an object of the present invention is to make it possible to inject water for checking drain drainage from inside the apparatus.
