Thanks guys.
Mick you may be right there is no check valve in there but I am hoping the 45 degree angle on the Y piece will be enough to grab the heavies with the yabby pump action providing sufficient pressure to drive it into the bucket. Only time will tell I will let you know how it goes.
Bunnings does sell those check valves I saw them yesterday.
its a great build mate and good use of another tool which barely gets used (yabby pump) I made a similar setup my best adize i can give you is drill a
very small whole inside your pickup tube abd place a nail small screw though because the flat rocks can get rally jammed in there when your poking around. goog luck on the colour mate
