Once in the basin the water will recirculate with help from a submersible electric pump. No plumbing is required simply assemble and fill the fountain and plug it into a standard indoor electrical outlet. *Color can vary slightly on each fountain. Lighting can be different indoors and out as well as differences in computer monitor lighting. Some fountains may appear darker because of the lighting in the room. Therefore slight color variation is not a cause for return. Features of the Cascading Wandering Leaves Tabletop Fountain w/LED Lights: Soft/no water sounds are perfect for those that enjoy the beauty of a fountain but don't want the pronounced water sounds.
