Attaching a nozzle

Attaching a nozzle, in most situations the nozzle  is screwed into a coupler,  as shown in the pictures below.

The N pump in these pictures has a one inch outlet, and most of the nozzles have a one inch thread.

By doing it this way, it saves on pipework and time, it also means the sump / pool can be shallower

If the nozzle is not water level dependant the water level need only be deep enough to cover the pump, typically 24-26cm in depth

If using a level dependant nozzle the water depth should typically be 40-44cm in depth.
