From series 1 to 4 they used traditional hoses from the 1980's such as a hosereel with a garden hose style nozzle and a layflat jet with a valveless nozzle which means the flow of water is constant and cannot be closed
From series 5 to 8 they used dark red fabric hoses with old fashioned brass nozzles
From series 8 onwards they have yellow hoses for sticky foam.
From Heroes of the Storm onwards they use bright red Rubber hoses with a more modern and traditional pistol style nozzle
In Deep Trouble for Sam, a special hard suction hose, known as a "Ejection Pipe" was used by Penny Morris to remove the soil which was trapping Sam in the hole in her garden. This is a special type of hard suction hose because it can remove soft debris as well as water unlike most conventional hard suction fire hoses. It also has a mini electric motor pump built into the inlet coupling which means it doesn't require suction from the main fire pump.
