Level dependant

Level dependant is in reference to some fountain nozzles, allow these pictures to show you. The nozzle shown is a cascade 90T

	Both of these pictures the nozzle set up is wrong. It may look correct, until you realise what it should look like.

	Both of these pictures the nozzle set up is correct. The picture on the left is what it should look like when working, as you can see there is quite a difference.

Spot the difference?

In the wrong pictures the nozzle base is mounted just on the surface of the water so the water jut shoots through the nozzle orifice.

When it is below the water level it sucks in air, giving a foaming effect. consideration should also be taken as to the dimensions of the pool as to the nozzle mounting height.

When the pump is running, if the pump pumps too much water into the air is is possible to reduce the height of the pool, making the nozzles not work, since the water level has dropped.

* You cant see the nozzle that well when its working correctly
