As mechanical equipment is staged for use on the rigs, nozzles on pre-connected hose lines can also be readied for action. For the smooth-bore nozzles, nothing needs to be set except for the correct tip size.
For combination nozzles, make sure the correct pattern is set — straight stream should always be selected. If there is an option for the amount of water to flow on the nozzle, it needs to be set to the right gallons per minute.
