catchment tank overflowing the top

[birdmove]

A hose won't do it, because you have to get ALL the air out of the tube. You have to submerge the entire assembly in the tank, and then turn it over (like a summersault), which will let the air escape. I tried filling the tube with water. No go. It won't force the air bubbles out any other way.
As I described above, once I loosened the cover and pulled it back a bit, so I had some room, it took me all of a minute to bleed the air bubbles out and get the tube full. Tim had told me sometimes it doesn't go so easy, but now I know how to do it.
