EASYPRO Waterfall Diffuser 23" Universal Spillway — Low-Profile, Reversible Smooth or Natural Cascade

The EASYPRO UWD23 ECO-Series 23" Universal Waterfall Diffuser is a robust, low-profile spillway that creates smooth professional waterfalls and can support rock or block veneers.

The UWD23 is engineered to make waterfall installation fast and reliable. Its 23-inch width and reinforced vertical rib design deliver an even sheet or natural cascade of water while remaining easy to hide behind stonework. Built for streams, pools, block walls and formal features, this diffuser accepts high flows and can be joined to a second unit for wider spillways.

How does the UWD23 produce a consistent waterfall look?

The diffuser uses a precision-cut lip and evenly spaced internal channels that distribute water across the full 23-inch opening. Flip the unit to choose between a smooth sheet or a more textured, natural flow without additional parts.

• 23" wide opening for full-width water distribution
• Even flow recommended for 1,500–6,000 gph
• Flip design allows smooth or natural cascade options
• Second 2" inlet available to join another diffuser

What makes this diffuser durable and easy to hide?

The UWD23 features a low 3½" profile and a heavy-duty vertical rib structure that bears load from stacked rock or block. Its compact height simplifies concealment behind stone veneers or in tight ledges, while the rib design prevents deformation under pressure.

• 3½" low profile for discreet installation
• Vertical ribs support rocks and blocks directly on the unit
• Reinforced polymer construction resists warping and impact

How do I connect and size this diffuser for my project?

The UWD23 includes a primary inlet and an extra 2" inlet that can remain capped or used to feed another diffuser for wider spillways. It performs well across a broad flow range, so match pump output to achieve the sheet thickness and sound you want.

• Primary inlet sized for common plumbing fittings
• Optional second 2" inlet for multiple units or alternate feed
• Best performance between 1,500 and 6,000 gph
• Easily integrates into streams, pools, and formal features

How fast and simple is installation?

Designed for quick installs, the diffuser mounts flush where you want the drop to appear and hides behind rockwork with minimal shaping. No specialized tools are required—set plumbing, position the unit, and backfill with stone or blocks to achieve a finished look.

• Low-profile makes for straightforward concealment
• Place and stack stone directly on the unit thanks to ribbed support
• Fits into block walls, beginning of streams, pools, and formal features

Who is this for: The EASYPRO UWD23 ECO-Series is ideal for pond builders, landscapers, and homeowners who want a durable, easy-to-install spillway that produces a professional waterfall. Choose this model if you need a compact, load-bearing diffuser that handles wide flow ranges and blends cleanly behind stone, block, or pool ledges.
