Fire Water Pump Hose... NPT and Industrial Pipe Thread the same? and NST?

[zeuspaul]

I don't think I will get 100 gpm out of the Honda WH20 as I indicated before. I pulled some numbers off a pump graph. 100 gpm *feels* too high. I picked up the pump yesterday. Ill run some discharge tests to see what my real life gpm is. The chart shows about 25 gpm at 60 psi which is near the top end of the graph. There are losses in the hose and nozzle so maybe I'll get 20 gpm?

I paid about $645 for the pump. (it is difficult to find Honda pricing online....the main reason I post the price I paid) The list was somewhere around $730.

I paid $180 for the hose kit. I wanted something I could use right away. The 20 ft suction hose with strainer will be usefull. I am not impressed with 50 ft of cheap *blue* 2 inch discharge. I am going with the recs on this thread and will opt for 1.5 in forestry hose. If the losses aren't too big I may go for 1 inch forestry hose but I don't know how to find out? or a combo 1.5 inch and then 1 inch ala Hotwheels. 1.5 inch seems to be more standard.

I have been looking at nozzles. Schmism..who makes the nozzle you pictured? The handle might be nice to have if your at it for hours at a time.

Hotwheels may cost me some money. Now I am also looking at the Daveys pumps. A sprinkling system on one pump and a more powerful second fire hose pump sounds like a good idea. The second pump will have to be for next year assuming I survive this fire season. It's hard to tell when the fire season starts as it is almost all year.

I think I'll look at increasing the size of my water supply

zeuspaul,

Try the pump with 1" or 1 1/2" forestry hose before you spend any more money. I have a feeling that what you have will be adequate.
We commonly use pumps like the one I have listed below for our homemade "skid" units in brush trucks. They are adequate for these applications.

As far as nozzles go we buy from Darley.com - Fire Apparatus / Fire Equipment / Fire Pumps / Fire Truck . Here is a forestry nozzle http://www.darley.com/Account/_files/_246/112-123Nozzles.pdf . Notice the flow rating is 10 - 30 gpm.

You can also find this one in plastic which is much cheaper: Fire Nozzles (Brass, Fog, Thermoplastic, Aluminum, POK, Dixon Powhatan, United Fire Safety and more)

Just a thought, fwiw:

When the brush fire comes you may be running frantically everywhere dousing embers that fall randomly within your perimeter. It seems to me you need a hose light enough to drag all over the place quickly, so maybe 1.5 inch is too large to manage in this application.

I'll let the people who actually know something, tell us if this makes sense!

That's why we use a 1 1/2" NST to 3/4"GHT adapter and run 3/4" heavy duty garden hose as I stated earlier in this thread. We buy that black hose from Sams Club that comes in 150' sections. Easier to pull around and hit the hot spots. We actually us a Y adapter so we can run a 1 1/2" hose and the 3/4" hose off the same outlet.

To add even MORE sources (confusion?), I recently noticed that Baileys has begun to distribute lightweight forestry hose and nozzles.

personally, if it's a good working fire, i wouldn't want to be caught with my pants down, using a 3/4" garden hose. DNR supplies all the FD's with 1 1/2" forrestry hose, and nozzles here.

the garden hose, works great for clean-up, hitting hot spots, and using a peircing nozzle, to get into the subsoil levels for stubborn fires.

structural firefighting, we run 1 3/4" hose, and flow 90-100gpm @ 100psi at the nozzle. one man can work with that without a big struggle, but he needs a backup, to move the hose, and keep hime on his feet at times.

personally, i've had 120gpm, and 180psi, on a 1 1/2" handline, and held it, but, @ 280 lbs, 6'3", i didn't try and move with it

as for heating the pump, with the line shut off, just crack the nozzle enough to let a little bit of water flow ( kinda like a kitchen faucet). that is what we have to do in freezing weather to keep lines from freezing, and it will move enough water to keep the pump from cavitating, and getting hot.

lastly, i'm all for protecting your property, but please try and get a little bit of fomal training. there's millions of ways to die playing with fire, and i don't want it to happen to anyone who's reading this

Thanks Tallyho for the fitting. It came a few days ago.

I had a chance to play with the Honda WH20 gasoline powered water pump. A crude estimate of the output through 50 ft of 2 inch hose and a cheap plastic nozzle and no elevation head is fifty gallons per minute. (it took about thirty seconds to almost drain a 32 gallon trash can).

The flow seemed adequate for what I think I need. I would want more not less. It does reach the roof of my two story house. However fire season brings a lot of wind. I may have trouble reaching what I want with a lot of wind. I'll keep this one for this year but may consider a higher pressure pump for next year.

I doubt I will be dragging the hose much. I will probably station myself in one position and move back and forth about twenty five feet. I'll be dealing with falling embers for 45 minutes before and after the fire goes by. The fire front could reach to 100 ft of the house. If that happens I will be in the house to protect myself from the radiant heat. I'll have a second position but will set up a separate hose for that.

Mostly I'll be drenching the house with water. I feel more comfortable with more water and more reach. I am limited by the water supply. I am working on it now. It will be between eight and ten thousand gallons. 70 GPM and 10000 gallons gives me a little over two hours of drenching capability. 50 gpm could go to the hose and 20 gpm could go to a roof mounted sprinkler system.

I am looking at weeping 1.5 inch forestry hose. I assume weeping means the hose stays wet and is somewhat protected from fire.

I am a little confused on dual gallonage nozzles. 20 to 60 GPM seems about right for my pump capabilities. Does the nozzle work at 20 or 60 GPM, or is there a complete range of output between 20 and 60 GPM. I assume 20 is *idle* mode and I crank in 60 GPM when I need to turn it up a notch?? The rating is at 100 psi. Will I be ok at 50 psi or do I need a different nozzle?

I 100% totally agree. Protect your property, but put your safety 1st.

Your most effective water stream will be at 100 psi AT THE NOZZLE, depending upon which nozzle you use.

You could pick up a used proximity fire suit (aluminized), I'd give you my old crash fire rescue one, but I turned it in when I transferred out. They work great in radiant heat situations. The biggest obstical aside from that is air. A mask does you NO GOOD in low oxygen situations. Keep that in mind. All the filtration in the world won't help you when there is not enough oxugen to breath properly.

Good luck, stay safe.

DUAL RANGE NOZ 1.5"NH 20/60GPM

that nozzle has a variable pattern to it. stream vs fog/flood (a very wide disperse pattern)

for a given pressure, that nozzle will flow between 20gp at the stream setting to 60gpm at the fog setting.

likely the 20-60 is at max pressure (100psi) if you had a pump that would put out 100psi @60gpm you would get 60 gpm when in fog mode. with less pressure you cant move as much water per time.

with less pressure, as you increase the flow rate, the effective distance goes down.

think of it this way. turn you garden hose on (no nozzel) and fill a 5 gallon bucket. the water kinda pours out the end in a nice arc, but doesnt travel far, but fills it up fast. As you put your thumb over the end of the hose and start to close it off, you develop more pressure so the stream of water flies farther now. but it takes much longer to fill the bucket.
