i would imagine a length of airline hose could be used to suck out any leftover small airbubblesthe article nursie posted said:How do you get the water up there?
This is a question that I was always asked by first time visitors. I often said " I place my head under water and suck on the one end." And it makes them even more inquisitive.
Getting the water up there is very simple. You turn the water bridge upside down so that the openings are facing upwards. Preferably outside, and fill the bridge, until there is no air in the tunnel or in the elbows or extensions. Do not forget the anti-chlorine. You then screw on the end caps allowing as little air as possible to be trapped in the extension pipes and tunnel. When both caps are secure, you can go inside and at the very last minute, flip the bridge around that both of the entrances are under water. Unscrew the caps that are now under water.
What happens if the water level drops below the entrance of the tunnel?
The obvious. Water runs out of the water-bridge in both directions and floods your lounge with the content of the water-bridge. I have never allowed the water level to drop to lower than 1 inch from the threaded opening of the bridge.
