In any dredge, you will have 2 types of suction devices; either a suction nozzle or a power jet. A suction nozzle only works with higher pressure pumps. The recommendation is a minimum of 140-foot head lift for a suction nozzle. A power jet can run at a slightly lower head lift at a 130 foot, however it does require higher volumes.

06/12/2012 My idea is to set it next to a small creek and suck out from underneath the big boulders. I have a 2" Briggs and Stratton 3.5 HP pump which delivers 150 GPM. It appears to be supplying more than enough pressure and flow. Now to the problem my DIY suction nozzle. I made it out of 2" PVC and the water supply at 1 1/4".
