Supply hose? Our pumper has 14 lengths of 64mm (2.5 inch) - each length being a nominal 30 metres (about 100 feet). So about 420 metres (1400 feet). These are used for feed lines from hydrants and too other pumpers, and as attack lines if we see any need for other than our normal 38 mm (1.5 inch) attack lines. That amount of hose fits nearly all of our needs, if we need for a greater volume of water, or have a greater than normal distance from a hydrant, we call for a hose-layer that carries about 3 kilometres of 90 metre hose.
Yup, all we carry is 1.5" and 2.5" as well. Being rural, we have no hydrants. We either call in tankers through mutual aid or draft out of standing water supplies. We carry 30 feet of hard suction for drafting and have about 1100-1200 feet of 2.5" to supply water to the pumper. 800 feet of 1.5" for attack.
We have 4" L.D.H. here and we carry about 1000' on Engine 1, 1000' on Tanker 5, and about 1000' (I think) of 3" on Ladder 6. Our Mini-Pumper also carries 4" but I am not sure of the exact amount. We also have about 200' reverse lay 2.5" on the Engine as well.
We carry 1000' of 5" w/Storz couplings,100' lengths, and 500' of 3"hose w/2 1/2" couplings,50' lengths, on each of our 3 pumpers. The tower carries 500' of 5".
The fire department i am on, we use the common 5" rubber supply hose,1,000 and we also carry 3" supply hose too, and that is 1,000 foot of that too. we also use it as a attack line too. but it takes 3 or 4 firefighter to move tha t heavy hose around.
