Hi there Stricky, Mate....you wouldnt share how your valve works on your pump/sucker? I have a few spots where I want to be able to do just what you said about pumping the material directly from bed rock & through a sluice box. Here is some bed rock I have dug down to & put through my sluice box. I then used a 2" crevice sucker/pump to clean up the bed rock. I was classifying the material to 10mm before pttuing through the box. If I could use the pump to directly clean the bed rock & put it directly into the box it would be a lot quicker.
White pipe is my 2" crevice sucker/pump & the white buckets my 10mm classifyer buckets sitting on top of the material that I am digging down to the bed rock & processing through the box.
Sieve buckets
Some of the gold I am getting
