The sound of a babbling brook livens up a pool setting. This waterfall is molded from rocks of the Blue Ridge Mountains and looks great with even a small water flow. Base piece has a 3-inch notch for a built-in look. The filter pump can be used as a water supply in most cases. Rounded boulders and a wide ledge piece come with several small cast pieces to hide mortar joints. Side boulders can be placed as needed.
