If your going to build another, I might offer this suggestion. The way your water enters the eductor now causes it to change direction twice, thus increasing friction and reducing efficiency. I would introduce the water from the top and cut out one 90 degree direction change. Think of looking at it from the down stream end as shaped like the letter "d" or "b". That way the water flow wrap's around the suction tube and enters the jets with equal pressure to each jet. You may find that this allows you to either have more suction or reduce the rpm on the pump to have the same suction. Remember friction cost money. Dickb
It works great. This is my old one. I'm working a larger one. Regular jets mix everything up while pushing it into the sluice. This tri-jet drags the gold along the bottom and drops it out first.

Nice build. I hope it works great. Dickb
is it as simple as it looks or is there some secret workings inside?
Also how does it compare to a regular jet?
Yes..it's 16 gauge stainless steel.
Did you make this tri jet?
