The Cascade Nozzle is the single most popular effect used in commercial and architectural fountains through modern times. They can be used in a wide variety of ways to achieve spectacular effects. Whatever your plan or inspiration calls for, the Cascade can probably fill the bill. A water entraining venturi type nozzle, the Cascade augments its spout effect by adding water volume from the pool. In doing so, a very heavy, powerful effect is achieved with little aeration.
Cascade nozzles are used widely in architectural fountains, due to their high visibility and good wind resistance, exhibiting a very “hard” visual and audible impact suitable for large pools and outdoor applications where noise masking water effects are desired. The Cascade is water level dependent, and requires a controlled water level. In addition, opaque water walls are easily achieved when several nozzles are placed in close proximity.
- All Cascade nozzles are water level dependent venturi types. The surrounding pool water is drawn by venturi effect through the bottom of the nozzle.
- These nozzles can be submerged in water, but maximum efficiency is achieved if the water level is held to the dimensions given.
- If placed in fountains of more than one water level, check valves should be installed inline with the nozzle. (The discharge orifice of the Cascade nozzle is actually under water, and if installed in an upper pool of multi-level fountains, can cause the water of the upper level to drain back through the display pump to the lower level.
