Fountain Nozzle

which fountain nozzle should you use?

Your pump  came with a fountain nozzle or two. But you now want a change, what can you get? How high or wide will its effect be?

For different fountain nozzles see  Exclusive fountains As for how high or how wide that depends on the pump capacity. It is true to say that the bigger the pump capacity the higher the water will go, but there are different types.

SPRAY 

These usually have a disc of some description with an arrangement of holes to give a pattern. they do not need a particularly big pump for them to operate. You must be careful that the pump feeding them has a pre filter otherwise debris can get pumped up and block the holes. They can be mounted at the water surface. Due to the fineness of the spray they are susceptible to wind.

FOAM

These are basically a pipe with a venturi on the end. By forcing the water to go through a constriction it increases velocity and by some clever engineering Air is also sucked in, producing a "foam" The do need a powerful pump in order to work properly, rarely do they get blocked, but they must be mounted above water level to allow air intake.

PATTERN

These are basically a pipe with a shaped insert cleverly installed. The shape and direction of the insert determines what the pattern will be. But they emit a sheet of water, as opposed to the previously mentioned. Depending on size of pump determines pattern size and if it can be mounted at water level or not.

ROTATING

These have a series of "arms" which rotate about a central axis giving a very pleasing "swirling" effect. They are rotated by the pressure of the incoming water and by varying the angle of the "arms" the speed of rotation can be slightly adjusted. These can be mounted at water level but are not suitable for small pumps.

SMOOTH BORE

These are also known as "swivel nozzles" since they can be "swivelled" to point in a specific direction. They are used in leapfrog fountains. They produce an almost clear stream of water but are best used in multiples.

IN GENERAL

Water will fall as far as it is high. So for example if you have water which goes 50 cm high it will fall 50 cm. and there for if it is to be part of a feature the pool should be at least 100 cm across, since water can fall in any direction. you may also want to read the JW Rule
