Water resistance test? What do you want to do with it?
First of all, it depends on whether your squatting toilet is now buried in the floor of the toilet or has been raised, if it is currently flat, take out the squatting and destroy the luggage, connect the drainage pipe, and install the toilet after the squatting pit is filled. If it has been raised, remove the raised one, and then install a toilet. It depends on whether the toilet you are going to buy has front or back drainage, and then determine the size of the drainage pipe from the wall.
If you want to change the toilet to the east, then at least there must be a sewer pipe, otherwise how to flush the toilet when you change to the east, if you put a shed, it will not be good at that time, so I think you should think about it before installation.
It is also possible to be 1 cm above the floor tile surface, and the bottom of the toilet is flat as a whole.
Related, downstairs blocked your toilet and the water is not fast.
Depending on personal needs, if you are not sure for the time being, it is enough to leave a power outlet to facilitate the installation when you want it later.
