Low-level installation: If you install it in a relatively short place such as under the window sill, you may need to purchase a dwarf tank.

Conventional installation: If it is installed on a normal wall surface, in order to ensure greater momentum due to the water level difference, in addition to the relatively high water tank, a thinner water tank can be selected under the same conditions to save more space.

Lightweight wall (gypsum board wall) installation: If the wall is a light body wall, such as a plasterboard wall, it is strongly recommended to use a self-standing water tank.
