Water flows from the top of the fountain face and down to the basin where the water will recirculate with the help of the submersible electric pump. No plumbing is required simply plug the fountain into a standard indoor electrical outlet after you assemble and fill it. *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 Curved Stream 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.
