Not sure if I missed it, But the hose would need to have a 'Y' connection. The Y creates the suction. The bottom of the Y goes to the sluice box, A large hose from the top of the Y goes up stream for flow, a slightly smaller hose comes off the other Y for suction. The gravity of water weight creates a suction in the small hose.
@amylou59102 This is true if that were the type of dredge I set up. This is just a straight 1 line suction dredge. I have a pump and jet for the other type. In reality it would just be more pipe I would have to carry to the stream and I was trying to avoid that. I can get 100 GPM+ with this setup, It all depends on length and drop. I haven't found many areas that the Y set up would be effective because of the lack of drop.
Search for "" Gravity Dredge plans, schematics and tons of information for more advanced/semi-permanent operations."" This is where I got the information to build this dredge.
The flex tube is standard suction hose no ribs. I was told after showing this to another prospector friend that I should empty all the PVC sections into a bucket because Gold will settle and stay in the pipe.

Great job man. I agree that it is nicer just listening to the creek.

Thanks, I have turned the sluice into a 2 stage and will try it again as soon as dredging season opens again here in WA.

Interesting set up. Does the gold not stay in the ribs inside the flexible tube?
