    Split your bed for at least dual LDH lines. This will allow for true high-flow forward lays.

    For large beds, have a maximum of 1,000-1,500 feet per bed (e.g., a 6,000 foot supply bed would have 4-6 divisions). This makes it easier to rotate the hose, even through single company drills.

    ~100' lengths work well in the rural setting, unless you have a system to pick up your hose, making lengths up to 200' feasible.

    Loading your hose with the couplings at the front of the bed is neater and generally saves hosebed space. Consider buying the hose in custom lengths to fit in your bed loaded with couplings at the front without the need for dutchmans.

    For example, you have a bed just over 15' in length (perhaps ~16 feet). Buy your LDH in 90' lengths. The hose will fold up and down the bed six times per length, and the couplings will always end up at the front, without a single extra fold.


    Reel vs. Bed: Use a reel if you want to build a water supply-only truck with an ultra-short wheelbase. Otherwise a bed is the ONLY way to go. Systems like the Angus FETCH or LiquidTrans don't hurt either (with a bed, that is).


    And don't even think about buying LDH with threaded couplings. You're on the right track with your permanent stortz fittings idea.

    all of our units have LDH in 100 ft increment besides the first section which is 50 feet. They are all Stortz fitings. We cary btwn 1000-1100 ft per truck plus another approx 1000 ft of 2.5 supply also. All pumping units cary another separate 25 ft of LDH in a compartment on the engine as a "cheater" piece, in the event you are a wee bit short you dont have to pull another whole 100 footer or if you are close you dont need to pull any at all and can use the "cheater" piece to connect directly to the hydrant. I would also like to say we are all hydranted here, but we have some older residential sections that have ony 4-6 " mains, and an industrial park with only 2.5 yard hydrant connections with a city hydrant easily 1100 + feet away.Hope this helps.

    LDH planning and usage - longlay

    For those using long lay of LDH.

    We are putting together a plan for our rural area. Planning is going on for installation of a rural water system (with hydrants). Hydrants will likely be only located in vicinity of houses/farms clusters. Goal is to have a hydrant within 3500ft (road) of each. Lay from nearest hydrant range from 200 to 3500ft.

    How are you configuring your load of LDH?
    1. One hose bed with entire load preconnected. What length/lengths of individual hose section? Using Storz?
    or
    2. Divided hosebed with varing length or combination of preconnected hose in each hosebed. How organize? What length/lengths of hose? Using Storz

    Hose on reel or flaked? What is working well?

    LDH is expensive but 5" Storz fittings are very expensive. Long lenghts of hose (500 or 1000 ft)will save $ but reduce flexiblity. Hose lay must be clearly plan out so you don't have an "extra" 300ft of LDH charged when get to fire scene.
