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 måste alltså täppa till ändarna sedan tar man bort locken under vattnet
