Eco-Series Waterfall Diffuser – Dual UWD23 spillway set up, 46″ wide

The UWD46 ECO‑Series® Waterfall Diffuser is a professional‑grade spillway designed to create wide, clean, and visually striking waterfalls with minimal installation effort. Its low‑profile body makes it easy to conceal within rockwork or block walls, while the reinforced vertical rib structure provides exceptional strength for supporting large stones above the unit. This diffuser can be positioned to produce either a smooth sheet of water or a more natural, textured flow simply by flipping the unit. Engineered for high performance in ponds, streams, pools, and formal water features, the UWD46 delivers reliable, even water distribution across its full 46‑inch width. Dual 2‑inch inlets allow flexible plumbing options, and the diffuser handles flow rates from 3,000 to 12,000 gph, making it suitable for both residential and commercial installations.
