Cascade
Fountain Nozzle
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 voume
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,
ehibiting a very "ahrd" 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.
- This type of nozzle can set up a resonant wave
action in certain pools. If an undesired wave action
occurs, it can be eliminated by adding a copper surge
tube around the nozzle locations. This is a copper
tube, about 6" in diameter, mounted from water
level to about 1" above the pool floor.
- All Cascade nozzles are NPT thread.
