Abstract: A self-contained module installed in the side walls or deck of a pool or spa is connected to the pool or spa plumbing system, and converts the turbulent water supply of the system to a laminar sheet of water which free falls into the pool or spa in a manner pleasing in sight and sound. Narrow, elongated spouts prevalent in the prior art have been reduced to a short, compact, economical and structurally stronger emitter owing to the provision of components including an apertured conduit, or "flute", traversing a relatively large manifold chamber open along an element.
