Actually, we didn't use a helmet to keep anything out of the muck, we didn't have any muck. But if we did, I'm sure our chief would have gladly donated his lid to the cause, as he wasn't using it for anything else.

I'm the rookie and I'll quote you on that when needed. Should work, right? TCSS

My first department was an unhydranted district, and we relied on water supply operations much like are described above. The device we used was called a transfer device, but was only good for moving water from one dump tank to another. As long as we kept the tankers moving, we could flow at 750 GPM indefinitely.<br />

<br />
Notice in the photo below that the tanker is set up with two dump tanks and the transfer device is set up to move water into the tank that is drafted from. At the same time the engineer is drafting, he is running a discharge solely for the transfer device which is using Venturi to move water from tank 2 to tank 1. He has also cracked open his tank refill and recirculate to allow the tank to refill so he can leave the scene fully in service.<br />

Ok I get it. The smaller hose is only inserted part way towards the discharge end of the larger hose so the siphon is created inside the larger hose, right?<br />

Who's helmet do you use? The Chief's or the rookie's?<br />

It is basically like a jet siphon when operating two dump tanks, in that the smaller hose is placed inside the larger hose. Tank water is pumped through the 1 1/2" causing the same siphon (or venturi) effect pulling in water around the smaller hose into the larger hose. The helmet was strapped on upside down to the assembly at the fittings, in an attempt to keep the hose out of the muck. We only practiced this a couple of times but it was effective in getting water.

It is basically like a jet siphon when operating two dump tanks, in that the smaller hose is placed inside the larger hose.

The helmet was strapped on upside down to the assembly at the fittings, in an attempt to keep the hose out of the muck. We only practiced this a couple of times but it was effective in getting water. Back then, we never worried about flow rate so I cannot tell you how much it flowed. Maybe one of these days I'll round a crew up, deploy it and figure it out.
