Large Diameter Hose (LDH)-Do You Have It?
How many of you are currently carrying large diameter hose? I am talking about 5 inch diameter or larger.
How much of it are you carrying on your units?
We have 800 feet on our Engine 3. It takes up alot of room, but is well worth it.
Also, is it set up for quick couple or are your connections threaded?

large diameter to my company is also 4". in most areas we simply do not have the water supply to run that, shuttling tankers back and forth just trying to keep up, the bordering towns however run 5 inch line, 0ur 4 inch is cuppled for 5 inch incase we need to hook into their line which has happened on occasion

Standard thread is the more common in the fire service. Bigger thread, easier to connect and go. Gaskets are a problem reguardless of the hose size. They dry rot (lack of use, or overuse) from water then drying (I think its a bacterial thing) plus when you have Lou Ferrigno tightening the couplings (a little too hard) you compress the gasket much more than needed. Gaskets are like any other tool we have, subject to abuse and wear and tear

I assume split as two 1250 lays? 2500' would be hard to maintain being 5" LDH for volume or pressure into the engine without a inline Engine

2500' in one lay on the hose bed. When we test this, we have to use a hydrant just to fill it all. We have never had any trouble maintaining pressures or volumes once the system is completely up and running.

We carry what the NFPA requires for engines both in 4" LDH and 2.5" hose. Most engines have at least 600 to 800 of the 4" LDH.

Both of our engines have 1,800' of 5" on them our first due engine has two piston intake valves on it. We carry 5" to 4" storz adapters for neighbering companies.
We have two 1,000' lays of three inch with national standard couplings, we also have to carry alot of adapters for it because a few stations still have pipe and pittsburgh 6 threads on their supply lines.

We currently have 1000' of 4'' with storz 1200' of 3''NST, and 2 cross-lays of 1 3/4 that are 300' NST, we also carry fittings on this truck.
the reason for so much hose on our trucks is 60% of our area doesnt have hydrants....

Our base pumper carries 4000' of 5" our two attack engines and tanker carry 1000' each of 5" and each rig has at least one 25' and one 50' pony length all storz connections. We are a very rural department without any wet hydrants, our supply is always maintained by drafting from a pond down the road, or hitting a dry hydrant that we have been strategically locating throughout our district as have neighboring districts.
