The universal waterfall diffuser is a fast and easy way to create professional looking waterfalls. Waterfall spillways are the perfect choice for Just-A-Falls (pondless) systems, signs, swimming pool features and other installations where a cascade of water is desired and filtration is not needed.

Made to last and faster to install than any other spillway on the market.

This ia  how they work: water enters the diffuser and is depressurized. Water then flows over and under the vertical dividers resulting in an even flow of water at the source point.
 

• Inlets: (2) 2" FPT Spinweld
• Ideal for use at beginning of streams and in block walls, pools and formal fountains.
• Super strong vertical rib design creates a nearly indestructible diffuser.
• Low profile design of 3 1/2" makes them easy to conceal

• Can be used in multiples for wider applications.
• Dual inlets - Easy to cap one off if only one needed
• Made in the USA
