Suction flow over the lower blades turns the upper blades, which in turn pulls air and water through them, till the hose is primed . . . at least, that's what it looks like to me.

Yes, but I would think that the vacuum needed to pull all the air out of the hose could not be created in this manner. I understand HOW it's SUPPOSED to work. I just don't see it actually working.

My guess is, to actually make it work, the flow paths would have to be somewhat different than shown.

From the description, I believe the doo-dad pushes water into the vaccum hose instead of trying to suck the air out. However, as drawn the doo dad would pull on the hose.

I have something that looks almost exactly like your drawing. It's orange, with 2 white fan blades inside. They seem to be attached by a shaft running through the middle of the device, and when I turn the blades of one, the other turns too. The diameter of the ends are different sizes though, unlike your drawing. One end is about 1 1/2 inches in diameter, the other is close to 1 3/4 inches. It's been in my shed forever, and I may have used it once, although I really don't remember. You can have it if you want it. Maybe a moderator can help us facilitate me sending it to you. Not sure what shipping would would be, I'm on Long Island, in NY. Worth a shot I would guess. The price is right, free, lol.

Did you fix that picture?
Anyway, I take it back, as drawn the Doo-Dad will fill the hose.
I want one - how clever!
BTW - Nice drawing!

That's fine with me Ben, thanks. Always glad to try and help a forum member, as this forum has helped me so much! JCG, shoot me an email with your name and address and I'll get it out to you this week.

That would be fantastic! And yes the diameters on the ends are different given the one end goes into the skimmer and the other into the end of the hose, I had just neglected to consider that in the drawing.

Many thanks,
Jim

Many, Many thanks Tom !!!
Also changed the drawing to reflect your observations (although can't promise the proportions).
Thanks Again,
Jim
