Hi Panos, here's a hose drill using the 4821 fire engine and the 4825 hydrant set. I'm assuming that you have a crew of eight, a driver (who is also the pump operator and usually, too, looks after communications with control), an officer-in-charge (he sits next to the driver) and six firefighters. (Six is good because it allows you to have two BA (breathing apparatus) crews of two each and still have two crew spare for for other duties. I always have the driver wearing a green over-jacket:

Here's drill 1:
1. Two crew take the standpipe and hydrant key and hurry to the hydrant.
2. At the same time, two crew unhitch the hose reel from the rear of the fire engine and start running towards the hydrant plate, having handed the loose end of the hose to the driver/pump operator at the rear of the fire engine.
3. The hydrant crew, open up the hydrant, insert the standpipe and when the crew with the hose reel reach them, one of the hydrant crew connects the end of the hose to one side of the standpipe while the other inserts the hydrant key and prepares to turn the water on.
4. By now, the driver has connected the other end of the hose to the inlet point in the centre of the pump.
5. Another crew member has, meanwhile, unrolled the hose reel hose and connected it to one of the pump outlets and is now ready to use the hose. (You can have two crew holding the hose, one holding the nozzle [strictly speaking, it's called the branch] and the other the hose just behind the first one.) At this point the driver signals to the hydrant crew to turn the water on.
6. The crew member holding the branch signals by raising his arm that they are ready and the driver then starts the pump.
Using the water pump provided with the 4825 set, you can connect this to the other side of the hydrant and pump water through the hydrant to the pump on the fire engine and through the hose held by the firemen.
Hope this makes sense as it was done in a rush.
Tomorrow, I'll try and do a drill for pumping water from a pond or stream.
(I hope you've got spare lengths of hose, btw.)
