Before use, make sure to tighten the top nut tightly to prevent air leakage. The straight tube is the inlet, and the corrugated tube is the outlet. When using the pump, insert the straight tube into the liquid to be drawn. Squeeze and release the pump ball with your hand, and the liquid will naturally flow out. When drawing liquid from a high to a low level, stop squeezing and releasing when the liquid is full and flows out of the tube. Use the siphon effect to let it flow by itself. When not drawing the liquid, you can loosen the top nut or detach the inlet tube from the liquid surface. If you want to draw liquid from a low to a high level, you must continuously squeeze and release the pump ball!
