    Default Does anyone have .................

    something like this ? I was out driving by our Meijer's store that is being built and when I found the FDC it was 5 " Stortz vs the 2 two andd halfs we normally see. The closest hydrant is about 100' feeet away and I thought this would be a much better and easier way to feed the sprinkler system. So like I said anyone else got an LDH sprinkler intake ?

    Default LDH sprinkler intake

    We were just out this morning doing a pre plan on the new NAMSA building and discovered the same thing 5" locking storz connection with a (private) hydrant within about 100'.

    We still have 3" conections for standpipes and sprinklers, but since we went to 4" hose, all new construction with sprinklers and standpipes will have 4" LDH connections for same! We use 4" to 2 1/2" adapters to feed sprinklers and standpipes.

    All our FDCs are 3", but our SOPs state that we supply them with 5"hose via a 21/2x5" adaptor. We keep the adaptor and 50' of hose together in a comp. for this purpose. I really dont understand this. Maybe ya'll do?? Also, rode by one of our new apartment complexes the other day and found they had 1 1/2" intakes on each building for the residential sprinkler systems. Also, the complex had dry hydrants (in addition to standard hydrants) and we dont have a piece of hard suction hose on the whole dept....lol

    We make all new construction that require sprinkler to have 4" LDH couplings.

    I've seen them, I like them, but I don't have any in my jurisdiction.

    The Storz on the steamer connection of a hydrant is a trick setup, too. I don't have any of those either.

    Haven't seen any yet. All of everything in Maryland (well, almost) has 2.5 NFH Couplings because many years ago, the Maryland Fire Service got together and had a law passed that REQUIRED all Fire Hose Couplings to be National Standard Fire Hose Thread. Since Storz doesn't have threads.......... There is LDH in Maryland, but I have no idea how they got past the law. Stay Safe....

    Like 159 said, we got one at the new NAMSA building, and I believe we may have them at 1 or 2 of the other newer buildings, but I'll have to check........

    In my first due and from what I have seen driving around, most new buildings have 5" storz connection at the FDC. I do not know if this is required by code or not, but I am assuming that it is. I am also seeing a lot of hydrants being placed approx. 100' from the connection. Hope this helps.

    We are getting more and more connections with 5in inlets around here. We don't require it, but its nice.

    At least in Ohio hydrant need to be within 75 feet.

    Cheers,

    All the building around here that have FDC are of the 2-1/2" inlets. My department supplies them via 4" LDH with a 4" storz X 2-1/2" adapter.

    This works well. We try to make sure the lay out is short. I am still under belief that suppling FDC's with LDH is wrong and using the 2 2-1/2" hose lines or 2 3" hose lines to supply a FDC is far better.

    The 2-1/2 and 3 inch hose can withstand higher pressures than the LDH, but the LDH can flow more water with less friction loss.

    I know that I am opening a can of worms here, but hoses being used that are the smaller line are constructed to handle the higher pressure.

    I have seen pressures as high as 250 to 300 pounds or better going into FDC's to get the correct pressure up on higher floors or to supply the system correctly.

    I am also in favor of NOT having any hose intakes or discharges on the pump operator side of the apparatus for safety. Have them all on the right side or rear of the apparatus. Another BIG can of worms here. :-)





    Stay Safe & Well out there.....

    Having a 5 inch stortz FDC intake for a single story warehouse or commerical occupancy sounds like a great idea. But I would be a little skeptical using it on any mid or high rise building because of the pressures needed for the upper floors.

    The Little Twp. only has two occupancies with FDCs (grocery store & nursing home).

    Both are double 2 1/2" connections and our SOG is to connect two 3" lines to them.

    Our code requires a 5" storz connection.

    LDH is available in supply and attack pressure ratings. Make sure you have the right stuff and you have all of the advantages of LDH with none of the drawbacks. (Except weight!)

    We went thru about 3 years ago and had all properties with a FDC change over to a single 4" Storz connection.

    Default Storz vs Stortz

    Ok, in my original reply to weruj, I spelled it Stortz also, then I noticed several other people had it spelled Storz, so I edited my post and changed the spelling. Now I googled it and found sites with it spelled both ways. Lets just say the connections for the BFH.

    We have a city ordinance and building code that if you have a sprinkler, you must have a 4" STORTZ coupling for the sprinkler connection. That was enacted a long time ago, not sure when. Buildings that had the 2 2 1/2" fittings were to be retrofitted to match the 4" Stortz within a certain time limit. Used it once, was much better working with one big hose with an easy connection vs. 2 smaller hoses with threads. Just makes things a little quicker.

    Keep your head down and your powder dry.

    All of our new construction commercial, assisted living, nursing homes, Apts. and the like have 5" storz intakes.

    Fortunately, we haven't had to use them for real, yet.
