Quad Roll Hose Lay

[@codylokan2375]

Try pulling that inch and a half up steep slopes. Realistically need like 5 people to effectively do this on and kind of terrain. And quarter turn is a better option.

Why throw the hose into green brush where it can get caught on branches slowing progress instead of back along the hose lay? What are the advantages and other disadvantages?

I have a couple of questions. What size of hose is being used? How does the engineer/driver know when to adjust the pump discharge pressure? What is the gpm being flowed?.

[@RespectableRSYt]

In forestry proper nozzle pressure isn't as paramount, when they get far enough they should call back for more pressure.

@Lee H
Really good questions.

Sorry, this is an older thread, but it's new to me.
Standard trunk line will be a 1-1/2" specifically wildland fire designed for weight, pressures, and unusually adverse conditions-not heavy structural hose. In our progressive hose lays we will also include 1" laterals every 200' and 100' of 3/4" mop-up line per lateral.
To your next question- A good operator will have established multiple avenues of comms. prior to engagement. If the radio fails, there will be some sort of relay set up to provide information from the nozzle to the pump operator. It may be a crew member in good view of the engine and nozzle using hand, voice, or radio comms (lookouts at higher elevations are good for this purpose) to relay pressure and status info back to the operator. In extreme cases where all comms may be sketchy- you don't need to be there.
I will-however- continually watch and feel my supply and work lines for rigidity. This will help me know if my head pressures are meeting the terrain and demand dynamics.

How many gpm is the nozzle flowing?

[@KosukiFire]

Depends if it is a 1" or 1.5" hose. My dept has 1" hoses with variable GPM nozzles. Ours ranges from 10 gpm to 60 gpm @ 100psi. On mop up Ill keep it around 20 gpm and on attacks im 40+, we have a 1800 gal pumper tanker with a 1250 certified waterous pump. So ill run it at 60 gpm if we ave a secured water source.
We are a smaller volunteer department with little budget, so we use 1" hoses which the county supplies, however, having grown up in California(im in MT now), id prefer a 1.5" hose,with nozzles that range from 30-150 gpm.
With the higher flow variable and changeable nozzles, Ill use a 1.5" smooth bore wit ha 1" tip all day. I like the forestry combo nozzles for the 1" hose, but for a 1.5" I was maximum flow and a tight stream.
If you use a 1.5" line or bigger with smooth bore it is worth getting a stream shaper. Due to our budget, I paid for one out of my own pocket for us to use. It will not only improve stream quality on a smooth bore , but it will decrease your turbulence, and that tighter less turbulent stream will shoot further and have less air to fuel fire.
