[QUOTE="HeadsUp, post: 28044, member: 414"] i think the hose is too long and put a restrictor on the end of the hose so if the hose is 20 mm ID , put a 16 mm tip on the end of the hose which could be a bit of 20 mm steel tube an inch long and bur the ends of that tube inwards by peening it with a hammer i think you also have the Y piece facing the wrong way , you want the incoming jet of gravel to drop down into the collector tube the hose on the left of the photo , is that the one you're sucking with ? i would cut it down to 2 metres or less " here is a nozzle i made earlier " except mine is aluminium which is easier to peen over [img]https://www.prospectingaustralia.com/forum/img/member-images/414/1378467811_nozzle.jpg[/img] ps . where did you get your pump and how much ?
