    We use 5" LDH on all apparatus but still have the option of using 2 1/2" for little stuff if needed.

    Default LDH

    We use a 4 inch line off the steamer connection of the hydrant but also put gates on the 2 1/2 inch hydrant outlets just incase we might need more water. This has been adequate enough for us.

    Primarily 5", usually reverse lay to draft or hydrant.

    Our main attack truck will sometimes lay it's 4" up a driveway to be supplied either by tankers or for a split-lay with 5" going from the driveway entrance to a water source.

    We use 5", but also gate a 2 1/2" just in case.

    We also have to use 2 1/2" whenever we do automatic or mutual aid with two of our neighboring departments, as that's all they have. We also bought a couple adapters so we can use the steamer connection of our closest auto/mutual aid city, even though they don't use them. (They use strictly 2 1/2" supply)

    Default 4" LDH ??

    Just pretty surprised that nobody has noted they use 6", even though it is pretty rare. Actually I expected to see more user's of 4" ldh than there has been.

    Ok, 911WACKER, just so you you're not surprised anymore....

    We use 4" now, but that should change to 6" as we start replacing rigs.

    There are actually more 6" users out there than you might think, particularly in the south-west. Many of them use 5" as their primary supply line with 6" reserved for the Big Ones.

    We use both 5" and 3" as our supply.. Depending upon the situation determines which size line is laid...

    Right now we have 900 feet of 3 inch, and 900 feet of 2 1/2 on each of our engines. That setup has always worked fine for us, but the other 5 departments here have all gone to 5 inch, and we`ve finnaly realized that LDH is really the way to go now, so we`ve gotten prices and should be switching over soon.

    While I don't work for the departmnet i know Las Vegas Fire & Rescue uses 5 inch supply line and also a 2 1/2 inch supply line.

    Each pumper carrys 1000 feet of 5 inch suppy line.Each pumper also carrys 1200 feet of 2 1/2 inch supply line.

    Some units carry 600psi 3 inch supply lines for the Standpipe system at the Stratosphere Tower Hotel & Casino.

    So alot of supply line sizes are used in Las Vegas Fire & Rescue.

    Angry 2.5" Yes, for supply

    Yip... 2.5" supply line. I am currently trying to get the Town to purchase 5" and that is like pulling teeth...They don't want to understand the benefits.

    5" is the only way to go. we used dual 3" until we upgraded if you like to roll hose or have more manpower than you can use stay with the small stuff.

    Between our Engine and our HT we carry about a half a mile of 5" supply lines. Standard for the dept.'s around the area.

    My dept. uses dual 3" hose we have 1500 ft. We also carry 300ft of 2 1/2 hose in a reverse lay. I would like to go with 5" but it may be a couple of more years. Our area is primarily single family dwellings less than 2000 square ft.

    All our "domestic" hydrants have 3" outlets- so we use 3" hose. Each engine carries 500 feet (some more) in each side of the bed, one is a forward lay with a shutoff and wye so it can be used as an attack line as well, and the other reverse (we use it for standpipe leads or sometimes to "get your own supply" if you know the other companies are going to be a while.

    Generally the first due engine pulls in front of the fire bldg and the second engine backs down and leaves two lines for supply and then heads for the hydrant where it "relay" pumps to the first engine.

    Understand, typically we are only a minute or two away from each other so the second engine arrives pretty quick. And some of our hydrants may only have 40 psi. in them and some of our streets have more than 60 feet of rise in one block.

    My department has four engines. Two of the engines run only 3" supply line. You have a choice of one long supply line from both beds or split the beds for a double lay. The other two engines carry both 3" and 5" supply lines. All engines have 5" intakes, but only two have 5" discharges.

    Default Type of Hydrant hose

    We are using 4" hose with 3 1/2 couplings (a brilliant decision by a clueless Chief). Some members are pushing for total 5" hose on all rigs. With our very good hydrant pressure the current size is just fine and is not as heavy as the 5" will be.

    "... some of our hydrants may only have 40 psi. in them ..."

    When will we learn that it's not pressure that puts out fires but the volume of water. That's why we spend thousands of dollars on LDH ... to move higher volumes of water. That's why we spend hundreds of thousands of dollars on pumpers ... to develop pressure to move higher volumes of water.

    How many departments spend big bucks on 2000gpm pumpers and feed them with 3 1/2-inch supply lines ... or buy LDH and don't even know what their hydrant system is capable of supplying!

    Water puts out fires. Know what you have and how to move it. If you don't, everything else you do is meaningless.
    How much water do you have?

    Our area is completely hydranted, half high pressure, half "low" pressure. We use 5" supply on the wagon with a hydrasist preattached sitting on the tailboard.
