The drainage pipe is too long. What details need to be paid attention to when draining liquid? Can I help?

I encountered a very interesting problem at work recently. Our bucket was draining to the outside, and the outlet valve was at the bottom, so we connected a long pipe. I thought everything was fine, but it turned out that the drainage speed was super slow. When I looked carefully, the liquid in the pipe was barely moving. I think of gas. The gas will be on the pipe due to buoyancy. How can I explain why it does not flow? Ask for methods and analysis.
The main reason is that the position difference (pressure) is small and the resistance is large due to the long pipe. And whether the plastic bucket is empty.
Is the difference in height a matter of height? The barrel must be left open when it is emptying, otherwise there will be a vacuum, which is understandable. How do you understand tube resistance? ? ?
The height of a bucket, especially after half a bucket of water, and whether the height of the ground is consistent,
Oh, thank you Clover, is there anything else? If water cannot be photographed, is it the gas in the pipe, or is the position difference too small?
