Need some advice on 4" dredge sluice

It only includes what is in the picture. I am watching your 5 inch build also. What is the foot valve? Never mind, I went to Keenes site and downloaded the pdf that shows how they build their dredges. It is 4 inch dredge instructions, and shows the sluice setup.

Problem solved. gave up on the 6 inch build since gpaa and wegm both limit to 5 inches. Sold my 4" and bought a new looking 5" Keene. Been to WEGM property in Cleveland Ga. $90 down and $20 a month, best money I ever spent. Beautiful river in places. I cant brag on the gold since first trip when the current was slow and the water was clear my belt wore out. Second trip water was very stained and current was ripping. Using the 4" on the second trip got a little over a gram in 3 hours but that was better than any Alabama trip so far and there was a definite upgrade in size.
